Innovating the multi-stakeholder collaborative governance model is essential for addressing the China's urban renewal and developmental obstacles. It would also assist in promoting high-quality urban development. This study analyzes the practical pathways and internal mechanisms of collaborative governance in urban renewal. With Hangzhou as an example, the study adopts a case study and inductive analysis methods to explore these dynamics. The results indicate that: (1) Hangzhou's urban renewal has developed four governance paths. The first path is building a governance environment through an integrated management system and diverse policy tools. The second path is establishing a governance structure that coordinates the efforts of government, market, residents, and society. The third path is applying governance tools that combine knowledge-based discourse and physical technology. Finally, the fourth path is achieving governance outcomes that balance development, livelihood, and preservation. (2) Multi-stakeholder collaborative governance of urban renewal should encompass an integrated framework of 'synergistic environment-structure-means-outcomes.' This includes an environmental synergy through self-consistent management and coordinated policy innovation, a structural synergy via diversified interest coordination and differentiated power allocation, a means synergy through normative procedures and incentive controls, and a results synergy focused on balancing conflicting goals with universal sharing. These integrated mechanisms are designed to facilitate high-quality urban renewal through coordinated development strategies. Therefore, this study offers four key governance insights. Firstly, it highlights the principles of responsibility-rights coordination and dynamic adjustment to innovate management systems and policy tools. Secondly, it calls for allocating stakeholder power based on roles to build an inclusive urban renewal governance community. Thirdly, it proposes combining regulation and incentives for flexible yet effective governance approaches. Finally, it stresses balancing efficiency and equity to achieve coordinated economic, social, and environmental development. These insights provide valuable lessons for advancing urban renewal governance in the New Era.

Intangible cultural heritage (ICH) is a crucial cultural resource and an integral part of China's excellent traditional culture. Protecting, inheriting, and promoting ICH is significant for preserving historical context, strengthening cultural confidence, fostering civilizational exchanges, and building a socialist cultural power. After over two decades of efforts, China has achieved remarkable progress in ICH protection and accumulated valuable experience. Currently, ICH preservation is transitioning from "rescue-oriented protection" to "systematic protection", marked by new characteristics. This special discussion invites experts and scholars from ICH and related fields to explore topics such as ICH protection system construction, innovative protection models, and inheritance pathways. Based on their insights, the following priorities emerge for innovative protection and inheritance in the New Era: (1) Promote systematic ICH protection by emphasizing the relationship between ICH and its environment, implementing regional holistic conservation through cultural ecological reserves, and building a people-centered protection system. (2) As a crystallization of ethnic wisdom and a key bond for consolidating the Chinese national community, ICH must connect with contemporary life. Multi-stakeholder collaboration should facilitate its integration into modern society to achieve creative transformation and innovative development. (3) Technology and tourism can empower ICH protection and inheritance across multiple dimensions. However, the core objective of heritage preservation must remain paramount. Strategic integration of technological tools can deepen ICH-tourism synergies, improve heritage experience infrastructure, facilitate ICH preservation and adaptive reuse, and effectively support both rural revitalization and urban renewal initiatives.

China has currently entered a stock era of comprehensive renewal, while urban renewal has become the primary task and form of urban development. Japan, a developed adjacent country, has similar geographical and cultural backgrounds to China. As such, understanding its urban renewal can help to formulate and develop sustainable strategies for urban renewal in contemporary China. In doing so, this study aims to compare and discuss the differences in the characteristics of stages of urban renewal between China and Japan by analyzing the case of the process of urban renewal at Shibuya, Tokyo. It is found that urban renewal in Japan has gone through five stages since the Meiji Restoration, and there are significant differences in terms of time dimension, driving factors, location, and scale compared to urban renewal in China. However, from the dynamic development process, urban renewal in China gradually converged with the development characteristics of Japan in the later stages. Therefore, based on the inspiration from Japan's experience, this study summarizes the path and countermeasures for the future development of urban renewal in China: first, building a more refined and perfect urban renewal policy system; second, exploring the autonomous creation model under government led coordination; and third, using Japan's pioneering experience for reference and considering in advance the response to social issues.

Based on the unique geographical and historical background, red brick has become a distinctive urban characteristic in the Fujian-Taiwan region, with its complex cultural background endowing it with rich potential value. However, the current inheritance and continuation of red brick cultural genes face significant challenges. In this study, we apply scene theory to Quanzhou West Street historical and cultural district, which is the most representative red brick area in Quanzhou. This study adopts the framework of the five elements of a scene to analyze the evaluation process of carrier characteristics, behavioral perception, and amenity value. Through a combination of field research, in-depth interviews, surveys, and big data statistical analysis, we investigate the evaluation indicator system for scene amenities at two levels: the macro-level of the entire district and the micro-level of red brick buildings. Our research findings reveal: (1) The scene elements of the red brick historical district include spatial environment, functional medium, diverse groups, activity combinations, and value attraction. (2) The scene functions of the overall district environment include: historical artifacts, cultural displays, and consumption experiences. These three aspects are interrelated, but the overall satisfaction of Quanzhou West Street still needs improvement. (3) The amenities of red brick architecture can be categorized into four types: color aesthetics, texture, decorative details, and regional characteristics. These categories include 12 traditional architectural features such as red bricks, white stones, wood, windows, balconies, external structures, beam decorations, columns, bricklaying methods, internal spaces, main structures, and roofs. Finally, we propose principles for protection and renewal, specific measures, and strategies for controlling the architectural style of red brick buildings. Our research extends the empirical application of scene theory in China, and provides effective approaches for the protection and renewal of historical and cultural districts.

As an important bridge connecting the natural ecosystem and human society, the improvement of the value realization efficiency of forest ecological products significantly impacts the realization of sustainable development goals. This paper aimed to explore how the new quality productive forces can empower the value realization efficiency of forest ecological products and promote the sustainable and efficient utilization of forest resources. Based on the dynamic qualitative comparative analysis method, using the panel data of 30 provinces (autonomous regions and municipalities) from 2011 to 2022, this paper analyzed the multi-factor synergistic linkage effect of new quality productive forces in the process of improving the value realization efficiency of forest ecological products. The study found that: (1) A single factor couldn't constitute a necessary condition for the high value realization efficiency of forest ecological products, but the necessity of innovative productivity, technological productivity, resource productivity, environmental productivity, digital industry productivity and industrial digital productivity was gradually increasing. (2) The high value realization efficiency of forest ecological products had four driving paths: "innovation+environment", "technology+environment+industrial digit", "resources +digit" and "innovation+resources". The low value realization efficiency of forest ecological products had three restrictive paths: "green+industrial digit", "technology+green" and "innovation+environment". (3) All the four driving paths of high value realization efficiency of forest ecological products had spatial heterogeneity, and the "innovation+environment" driving path has significant time effect. The research results provided not only theoretical support for understanding the empowering effect of new quality productive forces on the value realization efficiency of forest ecological products, but also practical guidance for optimizing the management of forest ecological products and enhancing the value of ecological services.

Reconstruction of regional land use/land cover changes not only provides scientific data for climate change and ecological effect simulations but also enriches and improves global datasets with regional references. By examining and analyzing historical records on manor cropland from 800 to 1583, cropland measurements from 1583 to 1872, cropland surveys from 1872 to 2000, and population estimations and surveys from 800 to 2000 in Japan, this study reconstructs the national and regional cropland area in Japan over the past millennium and at eight representative time points, respectively. Then the temporal and spatial variations of cropland in Japan were analyzed. The results are shown as follows: (1) During the manor system period (800-1583), per capita cropland area of Japan was approximately 0.31 hm², with agricultural population constituting about 80% of the total population. In the period of the Kokudaka-based feudal system (1583-1872), paddy and dry fields accounted for approximately 60% and 40% of the total cropland areas, respectively. And the standard yield of rice per 0.1 hm² was 1.2 koku for paddy fields and 0.8 koku for dry fields, respectively. The unit "koku" is a traditional Japanese measure of rice, with 1 koku equivalent to approximately 30 kg of rice. (2) Over the past millennium, the total cropland area of the whole study area experienced four phases: slow increase (800-1338), gradual decrease (1338-1598), rapid growth (1598-1940), and sharp decline (1940-2000). At the regional scale, the overall trend in cropland area of the study area was similar, though there were significant regional differences. Spatial distribution patterns show that, over the past millennium, cropland in Japan was primarily concentrated in the Kinki, Kanto, and Chubu regions, with a trend of gradual expansion from the central region to the south and northeast. (3) The relative discrepancy rates of the total cropland area from the HYDE 3.2 and PJ datasets for 1200-1880 compared to the reconstruction results of this study are -37% to -70% and -69% to -90%, respectively. The study shows that per capita cropland area of Japan declined from 0.31 hm² to 0.12 hm² during the study period, while the HYDE 3.2 and PJ datasets report per capita cropland areas of approximately 0.06 hm² and 0.03 hm², respectively.

Floor area is vital influencing factor of urban regeneration development gains. The article, based on Shenzhen experience analyzing the rule of floor area determination in urban regeneration, presents the evidence for the strong conflict between market-oriented and planning technology-oriented floor area determination, which brings the unequal development right among the subjects, the huge profit gap among different projects, the higher floor area ratio, and the subordinate functional type of urban construction, etc. The conflict has been proved not good for improving the quality and efficiency of floor area allocation. Therefore, this article analyzes the cooperative transformation mode of urban renewal,and uses an economic benefit analysis model based on four indicators: demolition and construction ratio, demolition and compensation ratio, saleable housing price unit price, and profit margin. It analyzes the mathematical relationship between various indicators in different types of renovation projects and examines the economic relationship between the government, market entities, and original rights holders in urban renewal. As a result of these investigations, suggestions, for instance, separating the market-oriented floor area and planning technology-oriented floor area, developing the demolition and construction ratio-based rule of floor area determination, enhancing the guidance of the demolition and compensation negotiation, are identified for improving the rule of floor area determination in urban regeneration at the end of this article.

The integration of culture and tourism is becoming a new engine for boosting domestic demand in China, and the assessment of the potential for cultural and tourism development can help to reuse the built heritage of the city and renew it with high quality. Under the heritage conservation policy of integrated management, how to quickly identify and categorize built heritage with potential for enhancement, and how to gather multiple heritage resources to build a cultural and tourism network has become a key issue in cultural heritage renewal. Taking built heritage in the main urban area of Dalian as the object of study, combining field research scoring, geospatial, socio-economic, demographic and streetscape image data, we constructed an evaluation system of built heritage regeneration potential from three levels, namely supply potential, demand potential and regional security power, and further refined it with six elements, namely environmental value, ontological value, market demand, cultural renewal demand, regional resource conditions and tourism resource extensibility. Through the collection and sorting of heritage lists, the existing built heritage with development value was screened and identified, and the improved CRITIC and TOPSIS integrated evaluation models were used to comprehensively evaluate the development potential of built heritage sites, and the data of each element and criterion layer were visualized and analyzed. Based on the kernel density analysis, the joint heritage renewal areas were divided and the renewal priority of each area was determined. The results show that: (1) The differences in the development value of each built heritage are concentrated in the two aspects of supply potential and regional security power. (2) The demand potential, especially the demand for cultural renewal, is less different from region to region. (3) The higher comprehensive development value is observed in the urban core area. Based on the evaluation results of each element and the comprehensive analysis, we put forward the renewal mechanisms for the heritage development models in various regions. Finally, we select the most representative heritage sites with priority for renewal in each region, providing references for the protection and development practices of existing urban built heritage.

The imbalance between urban and rural development is a prominent contradiction in China's economic and social development. To fundamentally resolve this problem, it is necessary to take the path of urban-rural integrated development. The county is a crucial support for urban-rural integration. Accurately grasping the multidimensional spatiotemporal characteristics of urban-rural integration within the county domain and clarifying the mechanism by which element flow impacts urban-rural integrated development is of great significance for enriching the theoretical system of common prosperity in the New Era. Based on flow space theory, this study analyzed the theoretical mechanism of element flow on urban-rural integrated development and constructed an evaluation index system for integration at the county scale from eight elements: population, land, ecological environment, capital, industry, technology, management, and data. An empirical analysis was conducted on 64 counties in the Wuling Mountain Area, Central China. The research results showed that: (1) During the sample period, the level of urban-rural integrated development in the study area showed a continuous upward trend. (2) The number of low-level urban-rural integrated areas in this region was decreasing, while that of high-level areas was increasing, generally presenting a spatial distribution pattern of "hotspots in the south, and coldspots in the west," with the standard deviation ellipse showing a trend of moving from southeast to northwest. (3) The overall disparity in the level of urban-rural integrated development was decreasing, with intra-regional differences being the main source. (4) Fiscal decentralization and industrial structure had significant inhibitory effects on the integration of urban and rural areas, while fiscal expenditure and financial efficiency had significant promoting effects on the integrated development. The impact of these factors on urban-rural integration varied depending on altitude and whether the area was an ethnic minority autonomous county. To achieve high-quality urban-rural integrated development, it was necessary to focus on the spatial and temporal characteristics of urban-rural integration development, make full use of resource endowments and locational advantages to achieve differentiated development, and pay attention to specific factors affecting urban-rural integration. The research results can provide a scientific basis for the implementation of urban-rural integrated development in mountainous county regions.

The development of characteristic agriculture is an important approach to achieving rural revitalization and promoting county-level economic development by stimulating industrial vitality. How to combine resource advantages and transform them into industrial strengths is the key to build a high-quality characteristic agriculture industry. This paper selects 31 county-level characteristic agriculture cases as research objects, constructs a TOE and dual-dimensional theoretical indicator system, and uses fuzzy-set qualitative comparative analysis (QCA) to extract element combinations and examine the influencing factors and differentiated paths of characteristic agricultural development in China's county-level areas. The study shows that: (1) "organizational resources" and "crop varieties" are the core factors for achieving high-quality development in county-level characteristic agriculture. (2) The high-quality development of county-level characteristic agriculture presents mixed development models, including market-oriented, organization-oriented, and technology-oriented models, as well as outward development models embedded in elements and inward development models relying on endowments. (3) Non-high-quality development of county-level characteristic agriculture exists in outward deficiency models constrained by organizations and mixed deficiency models constrained by organizations-environment and technology-environment. (4) The integration of multiple resource paths from both internal and external drivers is more effective than relying on a single internal or external driver in constructing action mechanisms for high-quality characteristic agriculture development. Based on the above research results, this paper proposes diversified, complementary, and integrated development path suggestions for county-level characteristic agriculture in China, providing a reference for achieving agricultural and rural modernization.

Mammals hold crucial significance in the realm of biodiversity conservation. Nature reserves serve as vital zones that effectively mitigate the loss of species diversity. Based on equal-area grid, this study evaluates the abundance patterns of terrestrial mammals across different levels of threats, analyzes regions and species under protection gaps, considering both the broad scale of nature reserves and the finer scale of protective patches. However, there are limited traditional gap analyses that fully take into account the diversity of species and their spatial requirements. We integrate the concept of Minimum Area Requirement (MAR) of species populations as a new supplementary assessment metric to assess the sufficiency of nature reserve patches, and species with poorer compliance are considered as the candidate species under conservation gaps, replacing the single threshold division approach with a multispecies threshold estimation method. The results show that: (1) The richness of threatened terrestrial mammals decreases progressively from the biodiversity-rich southwest to the north, highlighting the importance of Southwest China, particularly Yunnan province, as a critical biodiversity hotspot. Additionally, seven key regions are identified as conservation gap areas, where nature reserves fail to provide sufficient coverage for the protection of threatened species. (2) The distribution ranges of a total of 92.06% of the threatened species overlap with existing nature reserves, however, the presence of the overlaps does not ensure the provision of sufficient conservation, as evidenced by the fact that seven mammal species classified as endangered and three mammal species categorized as vulnerable are subject to absence of protection coverage. (3) Half of the protected patches for each of twenty-two nationally important threatened species face area limitations under different population growth rate levels. The results hold significant implications for identifying priority conservation areas and optimizing the planning of nature reserves to safeguard mammalian biodiversity.

In the era of digital economy, rural E-commerce development is an important initiative to promote the construction of digital countryside. Based on the urban and rural data of 151 counties in the Yangtze River Delta, this study explores the impact and mechanism of digital rural construction on urban-rural integrated development through the spatial Markov method, the Dagum Gini coefficient method, and the multi-period DID, etc. It is found that: (1) The level of urban-rural integrated development of counties in the Yangtze River Delta as a whole has significantly increased during the study period, but it is characterized by unbalanced development and the formation of a "core-edge" hierarchical spatial layout. Against the backdrop of regional integration in the Yangtze River Delta, the overall disparity in county-level urban-rural integration shows a fluctuating yet generally declining trend. Notably, after 2019, regional disparities in urban-rural integration narrow markedly. (2) The comprehensive demonstration policy of E-commerce into rural areas significantly improves the level of urban-rural integration and development of counties, and the areas that have not been included in the Taobao village construction, especially residents in remote and less developed areas are more likely to profit from E-commerce construction. (3) Heterogeneity analysis shows that the rural demonstration county policy contributes to "pro-poor growth", and has a stronger role in promoting urban-rural integrated development in less developed areas in terms of educational attainment, remote areas, and economically underdeveloped areas. (4) Mechanism analysis reveals that the demostration county policy in the Yangtze River Delta region facilitates urban-rural integration primarily by breaking down information barriers and enhancing entrepreneurial vitality. This effect is particularly pronounced in areas with less developed digital living environments, where such interventions contribute more significantly to integration efforts.

The construction of nature reserve system with national parks as the main body is a major initiative to implement the idea of ecological civilization, and an important practice area for Chinese modernization of harmonious coexistence between human beings and nature, and thus has received multidisciplinary attention from ecology, geography, economics, law, sociology and other disciplines. In order to coordinate the human-land relationship and garden-land relationship of the nature reserve system, and to promote the theoretical innovation, governance optimization and upgrading of the legal system guarantee in the construction of China's nature reserve system, we have invited eight experts in the nature reserve related fields to carry out interviews. The interviews focused on four aspects, namely, Chinese modernization, innovation of theoretical system and methods, legal system guarantee and international compliance, with the theoretical understanding and practical innovation of the governance of China's nature reserve system as the core, and explored several aspects of the construction of the nature reserve system with national parks as the main body: the understanding of the complex human-land and garden-land relations and its complexity coping strategy; the management efficiency of the nature reserve system; the strategy of improving the management efficiency of the nature reserve system; how the construction of China's nature reserve system can demonstrate the advantages of Chinese modernization by linking it with the implementation tasks of important international conventions; and the innovative role of the legal system in coordinating the relationship between people and land, and the relationship between parks and the land. Summarizing the main views of the experts, we can draw the main conclusions: (1) The construction of the nature reserve system, with national parks as the main body, needs to respond to the governance requirements of the Chinese modernization of the interaction between human beings and nature, which is a harmonious coexistence of human beings and nature, in the aspects of maintaining national ecological security, guaranteeing the supply of high-quality ecological products, as well as coordinating the relationship between the reserves and their surroundings, in order to achieve the unity of "ecological protection, green development and improvement of people's livelihoods". (2) Coordinating the relationship between people and land is the key to promoting the modernization of the governance of national parks, focusing on the three core issues of the relationship between people and land, the relationship between parks and land and the synergy of the inter-provincial level, and defining China's national parks governance model as "integrated governance based on the synergy between the central government and the local governments", and through the design of effective mechanisms. (3) The synergy between ecological protection and community development in nature reserves requires further research on the important role of biodiversity in human society, and Nature-based Solutions are conducive to the formation of inclusive governance in protected areas. (4) The construction of a unified, standardized, and efficient national parks system requires the improvement of the leadership system and the development of a system for promoting the reform of the national parks system in a coordinated manner, leadership system and working mechanism for the reform of the national park system, forming a community of interests in the park and deepening the degree of integration between the park and the land. (5) The development of new quality productive forces is necessary to deal with the relationship between people and the land and the relationship between the park and the land, and the model of harmonious coexistence between human beings and nature that relies mainly on the market economy not only embodies the characteristics of the Chinese modernization, but also contributes to the mainstreaming of the work of the Convention on Biological Diversity in the work on biodiversity, and the formation of an internationally applicable model of biodiversity. (6) Cracking the problem of "human-land constraints" and properly handling the "park-land relationship" requires a top-to-bottom legal system to regulate national parks and escort the standardized use of natural resources. (7) The Belt and Road Initiative and the construction of ecological civilization complement each other, and China's nature reserve system can help the Global South to realize the equal importance of protection and development in global compliance, and provide Chinese wisdom for the construction of a community of ecological destiny for mankind.

Historic and cultural districts serve as vital carriers for the inheritance of urban and rural cultural heritage, and their sustainable renewal urgently requires deep resident participation. This study integrates value co-creation theory and sense of place theory to develop a driving model of participatory renewal: "perceived value-place attachment-value co-creation", examining how multidimensional value perceptions and place attachment shape residents' engagement mechanisms. Using structural equation modeling analysis of 338 valid questionnaires from Nanjing's Old South district, the findings reveal three critical pathways. First, residents' perceived functional value and economic value significantly enhance participation behavior and civic behavioral intentions through the full mediation of place dependence, indicating that instrumental dependence serves as a direct mechanism transforming material needs into actions. Second, perceived emotional value derived from cultural continuity exerts dual effects, directly driving both types of value co-creation intentions and also uniquely activating civic behaviors through the "place identity" pathway. This demonstrates that local emotions rooted in collective memory can bypass institutional constraints to generate spontaneous cultural stewardship. Third, community support exhibits paradoxical moderating effects: while it amplifies the economic value-place dependence linkage, excessive administrative intervention weakens emotional value's impact on place dependence, revealing tensions between institutional empowerment and grassroots cultural agency. These findings challenge traditional economic incentive paradigms by highlighting the catalytic role of cultural identity and emotional capital. Accordingly, a governance framework is proposed: (1) establishing cultural identity reproduction mechanisms through resident-led heritage interpretation, (2) implementing demand-tiered resource allocation that prioritizes functional necessities like sanitation, (3) developing adaptive community support systems that delineate administrative boundaries in cultural practices. This research contributes to urban governance literature by uncovering the psychosocial process from spatial perception to collective action, while offering practical strategies to reconcile preservation and renovation through value symbiosis.

The frontier of urban regeneration in some Chinese cities has shifted to university campuses and their surrounding areas, thereby co-producing innovation ecosystems that integrates ''innovation, production, and urbanisation''. This study draws on the Triple Helix Theory and develops an analytical framework to explain the formation and evolution of innovation ecosystems in China. Using this framework, it compares the trajectories and outcomes of two university-based innovation ecosystems: Nanjing University's Silicon Valley and the Nanjing University of Aeronautics and Astronautics Innovation Bay Area. The study has three main findings. Firstly, in both cases, universities and local governments collaborated to adapt university campuses and regenerate surrounding areas to co-create innovation ecosystems. This suggests that urban regeneration and innovation-driven development have become new frontiers of town-gown interactions. Secondly, the development of both university-based innovation ecosystems was led and implemented by local governments and universities rather than by innovation businesses. This state-led feature, partly due to their early-stage status, diverges from Western theories on innovation, which place businesses at the core of innovation ecosystem formations. Thirdly, the innovation ecosystems developed in three stages: upgrading material spaces, creating an enabling environment, and densifying collaborative networks. The success of each stage depended on alignment between universities and local governments regarding goals, implementation, and sustaining mechanisms. The findings offer national and local governments insights into implementing innovation-driven development strategies, fostering new quality productive forces, and promoting sustainable urban regeneration.

Biodiversity is the foundation for maintaining the security of the earth, human well-being, and economic prosperity. Biodiversity accounting can provide an in-depth understanding of the interconnection among biodiversity, economy and society, and provide information for the conservation and enhancement of biodiversity. Based on the international biodiversity assessment actions, this paper rationally divides the formation stages of the accounting system in order to clarify its development pattern and the accounting essence. According to the specific content of the official texts of the United Nations, it analyses the update and evolution of the international standards from the four dimensions of accounting logic, accounting scope, core accounts and accounting methods. In the light of the global biodiversity conservation objectives, the practical experience of international accounting and its reference value are explored from the four dimensions of scope definition, region selection, account design and indicator construction. Finally, combining the results and challenges of China's practice, this paper puts forward specific ideas for promoting biodiversity accounting. By strengthening the scientific understanding of the accounting system and expanding the practical paths to promote accounting, this study helps to promote the theoretical discussion and practical research on biodiversity accounting in China.

Based on the Global-Luenberger index derived from the super-efficiency EBM model, this study measures China's agricultural green and low-carbon development performance from 2012 to 2022. The regional disparities are examined from spatial and structural dimensions using the Gini coefficient bidimensional decomposition method, and the driving factors of regional differences are comprehensively analyzed from both endogenous and exogenous perspectives through the optimal parameters-based geographical detector. The results indicate that: (1) During the observation period, China's agricultural green and low-carbon development performance exhibited an overall upward trend, with the three major grain regions showing a development pattern of "eastern>central>western regions", and among the three functional zones, main sales areas achieved the highest development performance, followed by main production areas. (2) Regional disparities in agricultural green and low-carbon development performance demonstrated an overall convergence trend, with inter-regional differences serving as the primary source of overall spatial disparities, while differences in input factor development performance dominated the regional differentiation pattern at the structural level. (3) Among the three major regions, technological progress exerted a relatively high impact intensity on intra-regional disparities in the eastern region, whereas regional differences in the central and western regions were more susceptible to spatial variations in agricultural industrialization levels and fiscal support for agriculture. Among the three major grain functional zones, average temperature and agricultural structure had a relatively great impact on disparities in main production areas compared to main sales areas and production-sales balanced areas. The research findings provide important support for optimizing regional agricultural development strategies, promoting coordination in agricultural green and low-carbon development, and enhancing the quality of agricultural development.

The island is defined as "a small piece of land surrounded by water". Recently, island cognition has experienced a change from emphasizing insularity to emphasizing relationality. Since the 1980s, the understanding of islands has undergone a shift from emphasizing insularity to emphasizing relationality, focusing more on the understanding of "mainland-island", "island-island", and "island-sea" relationships. The shift in island cognition challenges the dichotomy of island/mainland and land/sea, and interprets islands more in terms of the mutual construction of space, society, and the land-sea environment. In terms of research topics, "mainland-island relationship" mainly focuses on decolonial turn, island colonization, non-sovereign island governance, and island geopolitics. "Island-island relationship" mainly focuses on archipelagic turn, island transport geography, island migration and the impact of informatization on islands. "Island-sea relationship" focuses on aquapelagic turn, island culture and identity, island sustainable development under climate change, and island-marine tourism research. The interpretation of mainland-island relationship is the discussion of the unequal power relationship between continent-island, the interpretation of island-island relationship is the cognition of the dynamic correlation of islands, and the interpretation of island-sea relationship is the consideration of human-land-sea interaction. The island is an important support for the implementation of future national maritime strategies. By sorting and prospect, this paper hopes to enrich the current cognitive dimensions of island spatiality and provide an interpretation based on the relational perspective for the governance of marine territory.

Urban development and construction is a major driver of cultivated land loss. Based on the panel data of 277 prefecture-level cities from 2000 to 2022, this paper employs spatio-temporal analysis to reveal the evolving relationship between urbanization and the "trinity" protection of cultivated land. Furthermore, it utilizes a two-way fixed effect model to empirically analyze the total and sub-effects of urbanization on this protection framework. It also explores the differences in the impact effects from the perspective of land, population and economic urbanization. The results show that: (1) During the study period, the urbanization level of all cities increased annually. Spatially, the distribution exhibited a distinct pattern characterized by higher levels in the east than in the west, continuous development along the coast versus isolated growth points for inland areas, and higher concentrations in provincial capitals compared to other cities. The level of cultivated land "trinity" protection shows an inverted N-shaped fluctuation over time, while its spatial pattern evolved from an initial unipolar pattern structure to a north-south dual-core configuration. The cold spots of the two clusters always coincide highly in the western region, while their hot spot clusters exhibit a dynamic seesaw relationship in space. (2) Urbanization exerts a significant overall negative impact on the "trinity" protection of cultivated land. Specifically, it leads to a reduction in both the quantity and quality of cultivated land. (3) Land urbanization leads to a decline in the level of cultivated land "trinity" protection, while, in contrast, population urbanization enhances it. (4) The heterogeneity analysis reveals that the negative impact of urbanization on the "trinity" protection of cultivated land is significantly stronger in major grain-producing areas and in cities with more favorable natural conditions for farming. Within the context of high-quality development, our findings offer theoretical and empirical support for advancing new urbanization and strengthening comprehensive cultivated land protection.

The modernization transformation of rural areas is key to implementing the Rural Revitalization Strategy and achieving modernization transformation. However, existing research on modernization transformation has not sufficiently explored the tourism-driven mechanism. This study takes Jijiadun village, a suburban rural tourism destination, as a case study and integrates the rural regional system theory with the "people-land-industry-governance" analytical framework to systematically reveal the pathways and mechanisms of rural modernization transformation driven by tourism. The study finds that the tourism-driven modernization transformation of rural areas shows differentiated characteristics and forms a four-dimensional co-evolutionary pattern of population transformation, spatial reconstruction, industrial reshaping, and governance innovation through the evolutionary path of "element reorganization-structural adjustment-functional leap". The tourism-driven mechanism is reflected in three-fold effects: as a catalyst for industrial integration, it updates the rural production system; as a conduit for urban-rural mobility, it constructs a new type of urban-rural relationship; and as a bond for rural governance, it coordinates multiple stakeholders. The modernization transformation of rural areas has a counter-effect on tourism development, presenting a complex and dynamic evolution process of the rural regional system. This study breaks through the urban-rural dual-opposition paradigm and constructs a "tourism intervention-system response-transformation output" analytical model to explain the mechanism by which tourism triggers the modernization leap of the rural regional system, providing theoretical references and practical pathways for the transformation and development of rural areas under the Rural Revitalization Strategy.
