Inclusive growth in counties is an important realization path to reslove the rural issues in the New Era and comprehensively promote rural revitalization. Based on the county data in 2015 and 2020, this paper constructs a county inclusive growth evaluation index system from the three dimensions of economic growth, social development, and common prosperity. The study uses the entropy-weighted TOPSIS method, kernel density estimation, and Thiel index to analyze the level of inclusive growth in counties. The research finds that: (1) From 2015 to 2020, the inclusive growth level of counties in China showed an upward trend, presenting a pattern of eastern > central > northeastern > western region. In terms of growth rate, the northeastern and western regions are ahead of the eastern and central regions. The inclusive growth level of poverty alleviation counties and key counties assisted by the national rural revitalization was below the national average. (2) The overall difference in the level of inclusive growth in China's counties between 2015 and 2020 decreased from 0.0364 to 0.0258, with intra-regional differences being the main source. In terms of dimensions, the economic growth has the largest variation, while the social development and common prosperity variation have the smaller variation. (3) The inclusive growth level of the county shows a pattern of "high-level difference in the eastern region and low-level balance in the central and western regions". The decomposition of the sources of differences between the east and the west shows that the differences in the eastern region mainly come from inter-provincial differences, and the differences in the western region mainly come from intra-provincial differences. (4) The identification results of obstacle factors show that the number of beds of social welfare adoption units per 10000 people, the number of industrial enterprises above designated size, the per capita public budget revenue, the proportion of employees in the secondary and tertiary industries in the total population, the number of beds in medical institutions per 10000 people, and the per capita disposable income of rural residents as a proportion of per capita GDP are the main obstacles to the inclusive growth of the county. On this basis, the study puts forward enlightenment and relevant suggestions for comprehensively promoting rural revitalization from the aspects of developing and expanding the county economy, enhancing the accessibility of public services for rural households, promoting the wide sharing of economic results, and enhancing the coordinated development of the county.

The county is the key field to realize the urban-rural integrated development, and the homestead system reform is the important starting point to promote the urban-rural integration at county level. In this paper, we intend to explore the internal connections between the county urban-rural integration and homestead system reform, analyze the mechanism of the homestead system reform promoting county urban-rural integration, and propose the corresponding reform path. The results indicate that: (1) The core of the county urban-rural integrated development is the free and equal flow of urban and rural factors and the profound integration of functions and the equalization of rights and interests. In addition, it is the basic driving force for county urban-rural integrated development to clarify the property right structure of rural land elements and encourage the optimal combination of "people-land-money" elements. (2) Currently, for the homestead system reform, "housing for all households" is the premise, "separation of three rights" is the foundation and "saving and intensive use" and "realization of property functions" are the orientation. The three rural spaces can be orderly adjusted through the withdrawal and arrangement of idle homesteads, so as to support the improvement on the rural infrastructure and public service facilities, and promote the optimization and reconstruction of rural space. The moderately released right of use can promote the development of rural industries as well as the urban-rural cultural exchanges, force the rural governance to be modernized, and push the multi-dimensional integrated development of urban and rural areas at county level. (3) To fulfill the demand of county urban-rural integrated development, we must first clarify the main direction of the homestead system reform in different counties and the reason for the reform of homestead system. Secondly, it is the main focus of the reform of homestead system to improve the marketization allocation level of homestead as a land element and increase its flowability. Third, in the context of digital rural construction, the homestead information management platform can be built with the up-to-date information technology, trying to raise the homestead management level, and provide support for the homestead system reform. Finally, taking the homestead system reform as a breakthrough, we should link various county urban-rural integration policies in combination with measures such as capital introduction and talent guarantee, and form an overall effect, which is the key to promote the multi-dimensional integration of county urban-rural development.

Based on the research perspective of urban-rural integrated development and regional coordinated development, by constructing a comprehensive evaluation index system for rural revitalization and new urbanization, using the coupled coordination degree model, LISA time path, LISA spatiotemporal leap, and geographically weighted regression model, this paper analyzed the coupling coordinated development level, spatiotemporal differentiation characteristics and influencing factors of 86 county units in Gansu province from 2013 to 2019. The results show that: (1) During the study period, the spatial distribution of county-level rural revitalization and new urbanization is similar, showing a development pattern of "high in the northwest and low in the southeast". Among them, the development level of rural revitalization and new urbanization in the Hexi region is the highest. The coupling coordination of rural revitalization and new urbanization in the Hexi region is the highest, while the coupling coordination of the Central and Southeastern Gansu regions is relatively low. Among the basic imbalance types and basic coordination types, the rural revitalization development backward type accounts for the majority in all the county units of Gansu, and there is no new urbanization development backward type. (2) The spatial pattern of the coupling coordination degree at the county level has a certain degree of smoothness. It has weak volatility in the local spatial dependence direction and spatial growth process and is relatively weak by neighboring cities' spillover effect or siphon effect. The coupling coordination degree at the county level is less affected by the spillover effect of adjacent county units, and the overall trend of high or low growth is more prominent. The local spatial correlation pattern of the coupling coordination degree is kept in a stable situation, and most counties have not experienced any transition; the spatial pattern shows certain characteristics of transfer inertia and path dependence. (3) The influencing factors of the coupling coordination of rural revitalization and new urbanization at the county level are different in space. The urban-rural income gap, urban-rural consumption gap, and industrial duality are not conducive to improving the coupling coordination between the two. On the other hand, the level of economic development and government regulation can improve the coupling coordination between the two.

Urban-rural integration is an important support for achieving common prosperity and moving towards Chinese path to modernization. Ecotype regions have long fallen into the dilemma of lack of development power, low-level circulation and decline of villages and towns. Urban-rural integration faces greater challenges. Exploring the path of urban-rural integration in ecotype regions is of great significance. This article proposes an innovative theoretical framework for realizing the value of ecological products to promote urban-rural integration. To build the urban-rural integration path of the combination of "value chain-supply chain-factor chain", this paper takes the Northern Guangdong Ecological Development Zone as an example to put forward specific strategies: first, build a full-chain value chain of ecological products, establish ecological material products, ecological regulation products The value realization path of ecological cultural products; The second is to build a cross-regional and urban-rural vertical division of ecological product supply chain, and establish a three-level spatial supply system of "the central city of Dawan district - counties and cities in Northern Guangdong - villages and towns in Northern Guangdong"; Third, establish the factor chain of production factor circulation and trade, and promote the urban-rural convection of population and land factors around the supply chain of ecological products. This paper has theoretical guidance significance for conducting researches in specific urban-rural areas, and provides an example for realizing ecological products' value and developping urban-rural areas in ecotype regions.
