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.

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.

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.

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.

The renewal of collective construction land is fundamentally a process of land development rights restructuring, which may lead to various conflicts of interest and become the major obstacle to planning implementation. The rights adjustment system based on the principle of balancing interests can help mitigate these challenges. Theoretically, the imbalance in rights distribution is caused by the dual effects of market dynamics and planning intervention, which can negatively affect the fairness and sustainability of urban-rural development. To address this issue, a theoretical framework has been constructed that integrates the adjustment mechanisms of land development rights from aspects of scale, type, and standards. Empirical analysis, using Nanhai district in Foshan city as a case study, reveals the mechanism of unequal rights distribution in the formation and development of collective construction land, as well as the government's planning interventions. The study identifies three models of rights adjustment: mixed development, joint redevelopment, and the "three vouchers" system. These models are applicable to different scenarios of collective construction land renewal and exhibit distinct evolutionary characteristics. Mixed development promotes redevelopment through negotiated profit sharing, but it may lead to government concessions and thus reduce the government's capacity for broader rights adjustment. Joint redevelopment links development responsibilities with specific projects, promotes a more equitable distribution of spatial rights and supports the renewal of industrial land. The "three vouchers" system establishes a spatial transaction mechanism for land development rights through the transfer of land use indicators and the reallocation of properties, thereby further enhancing the coordination of development rights across regions. These models exhibit a trajectory towards more scalable, diverse, and clearly defined standards. The study concludes with policy recommendations emphasizing the importance of incorporating rights adjustment mechanisms into the planning process, clarifying standards for rights allocation and adjustment, and establishing a systematic framework for transferring development rights between government and market actors.

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.

Based on the sample data of 8 prefecture-level cities in the Changsha-Zhuzhou-Xiangtan Surrounding Area from 2010 to 2022, this paper empirically analyzed the coupling coordination and driving mechanism of urban renewal and ecological resilience by using the entropy weight method, coupling coordination model, spatial Durbin model and other methods. The results show that: (1) From 2010 to 2022, the level of urban renewal and ecological resilience in the study area shows an overall upward trend, and the regional differences decreased year by year. (2) The coupling coordination degree of urban renewal and ecological resilience showed a fluctuating upward trend, and Changsha had always been in the high-level area of coupling coordination, and the development of its surrounding cities showed a trend of agglomeration. (3) Population agglomeration and economic development could promote the improvement of coupling coordination, and population agglomeration could also have a positive impact on the coupling coordination degree of neighboring areas. The increase in the proportion of industry and excessive government intervention would have an inhibiting effect on the coupling and coordination degree, and the impact of opening up to the outside world was still unclear.

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.
