Promoting common prosperity through rural revitalization is a great practice in China. However, it also means that the path of promoting common prosperity faces enormous difficulties, which requires scientific deconstruction of the path and clarification of the theoretical system of relevant issues. Based on the hypercycle theory, this study deconstructs the complex path of promoting common prosperity through rural revitalization. In terms of the reaction process, rural resources inside the countryside and the relationship between urban and rural areas are the starting point of the path of promoting common prosperity through rural revitalization, stable replication and innovative development are the core process of the path, and the endpoint of the path reaction is the material and spiritual common prosperity with Chinese characteristics both in the countryside and city. In terms of the circulation hierarchy, the path of promoting common prosperity through rural revitalization can be deconstructed into three stages: rural internal reaction circulation, rural overall catalytic circulation, and urban-rural system super circulation, which respectively point to different goals of consolidating rural functions, cultivating rural endogenous development capacity and promoting common prosperity between urban and rural areas, corresponding to different stages of practical discovery and theoretical research topics.

As a new type of agriculture, urban agriculture is related to the flow of urban-rural food elements and energy conversion, and it has become a new format for coordinating urban-rural integrated development. Based on the perspective of urban-rural integration and the flow of elements, the paper takes the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) as the research area, aiming to explore the process and mechanism of urban agriculture's type differentiation, functional evolution and spatial transformation, and to compare and analyze the logical mechanism between different typical types of urban agriculture. The results show that: (1) The three typical types of urban agriculture in the GBA, namely, community supported agriculture, migrant agriculture and leisure agriculture, have differentiated spatial functions, transformation processes, and spatial effects. (2) Community supported agriculture strengthens ecological functions through ecological planting and breeding, and realizes economic functions through short-chain sales, cooperative production, and live broadcast delivery, which leads to the improvement of space quality and the transformation of urban consumption of space. (3) Migrant agriculture emphasizes the economic function, and the transformation process of its material space is reflected in the non-grainization and concentration of cultivated land and the differentiation of community living space, which in turn brings about group exclusion and spatial isolation in social space. (4) Leisure agriculture emphasizes the social security function and the experience and emotional needs of urban groups, and reflects the differences and imbalances in social development in terms of spatial transformation, which further exacerbates the complexity of social relations and the differentiation of spatial benefits. (5) The functional evolution and spatial transformation of typical types of urban agriculture are affected by the comprehensive effects of multiple subjects such as the market, government, enterprises and individuals, and factors such as urban and rural economy, society, technology and culture have an important impact on the direction and degree of spatial differentiation of urban agriculture, and provide new pathways and new models for urban-rural integration through food, community and industrial linkages.

Resource-based rural areas are the key areas for comprehensive rural revitalization and common prosperity, and the integration of the three industries is an important starting point for the modernization of agriculture and rural areas. Based on the evaluation of the integration level of the three industries, the Industrial Logistic Symbiosis model and the Geographically Weighted Regression model, and taking Daye city, Hubei province, a typical national resource-based area as the research area, this paper analyzes the integration level and endogenous driving force of the three industries in the towns and villages of Daye city in 2020, and then explore the three-industry integration mode and endogenous mechanism under the background of resource depletion. The results showed that: (1) The level of three-industry integration in Daye has obvious spatial disequilibrium, showing a spatial pattern of "two towns are dominant, the west is high and the east is low", and each township has room for improvement in the three-industry integration subsystem. (2) The overall degree of industrial symbiosis in the towns and villages in Daye is relatively low. The industrial unit relationship is dominated by industrial symbiosis and parasitism. The industrial integration model is dominated by the primary industry-led forward integration and the secondary industry-led two-way integration. (3) Endogenous dynamic factors play a significant positive role in promoting the level of integration of the three industries in the study area. Among them, farmers, three-industry integration demonstration bases and industrial parks are the "main engine" of the integration of the three industries, rural cooperatives and leading enterprises play a key role in organization and construction, and agricultural production conditions and infrastructure conditions are the material foundation. (4) Under the action of different endogenous driving forces, the integration of the three rural industries in resource-based areas takes the main body cultivation, factor flow, channel construction and demand development as the four-wheel driving force, agriculture as the integration base and farmers as the integration center to realize the endogenous power improvement and the organic co-promotion of the integration of the three industries in the process of the flow of integration benefits, and promotes the revitalization of rural industries and the integration of urban and rural development in resource-based areas.

The development of the new path of agricultural industry is an important topic in the study of economic geography, and it is also an important topic for China's rural revitalization and agricultural modernization. Based on the theories of evolutionary economic geography and sociology of expectation, and by using qualitative research methods such as literature analysis, field research and in-depth interviews, this paper takes Yongfu Taiwan High Mountain Tea Industry as an example to build an analytical framework for the development of exogenous agricultural industries from the perspective of path creation and explore its evolutionary mechanism. The research findings are as follows: (1) Through specific analysis from five dimensions, including regional and extra regional assets, key economic and organizational actors, path creation mechanism, institutional environment, policy initiatives and future expectations, Yongfu Taiwan High Mountain Tea Industry has experienced two path creation stages and two new path development evolutions, realizing the development from scratch to diversification. (2) The development experience of Taiwan High Mountain Tea Industry in Yongfu reflects the new path development direction of exogenous agricultural industry under the path guidance, in which the integration of internal and external assets, cultivation of key subjects, diversification of path creation mechanism, institutional and policy environment support, and realization of different expected effects all have a significant impact on the new path development of exogenous agricultural industry.
