The Spatiotemporal Pattern Of Urban-rural Integration In The Central Plains Urban Agglomeration And Its Driving Mechanssm

The essence of urban-rural integration is the process of solving the large gap between urban and rural areas and the unbalanced development of urban and rural areas.The relationship between urban and rural areas in China has gone through three stages: urban-rural separation,opposition to openness and coordination,overall planning,and then urban-rural integration and integration.With the evolution of social and economic development,the relationship between urban and rural areas has undergone tremendous changes in rural revitalization and comprehensive poverty alleviation.The flow and exchange of urban and rural elements promote the formation of urban and rural economic and social development,structural balance,and the formation of a framework mechanism for urban-rural integration.This paper takes "how to promote the integrated development of urban and rural areas in the Central Plains urban agglomeration" as the core research question,and the research is in line with the perspectives of geography and planning,aiming at the development of urban-rural integration,which has good theoretical and practical significance.By combing the literature and analyzing the research issues in perspective,drawing on the theory of dual structure,growth pole theory,equalization theory,polarization-trickle-drop and other theories,the construction of "industrial structure-spatial layout-population mobility-public service-Ecological construction-policy environment" as the main line of theoretical analysis framework.Taking the Central Plains urban agglomeration as a research case,by measuring the degree of urban-rural integration of various cities and the correlation between each factor and the degree of urban-rural integration,combined with the theoretical analysis framework constructed,the driving analysis of the urban-rural integration of the Central Plains urban agglomeration,the main conclusions are as follows:(1)From 2015 to 2019,the overall level of urban-rural integration of the Central Plains urban agglomeration showed a growth trend,and the overall level of urban-rural integration development increased significantly.The development level of urban-rural integration in various cities spanned from the low-and low-level stages of urban-rural integration in 2015 to the medium-high and high-level stages of urban-rural integration at the end of 2019.(2)The urban-rural integration development speed and the urban-rural integration development level of the nine cities in the Central Plains urban agglomeration show obvious convergence.The performance is that areas with a high level of urban-rural integration develop relatively slowly,while in areas with a low level of urban-rural integration,the development of urban-rural integration is faster,and the gap between urban and rural integration in the Central Plains urban agglomeration is gradually narrowing.That is,the gap between the slowest-growing cities and the fastest-growing cities in the level of urban-rural integration has narrowed.There are differences in the roles played by each influencing factor and each index variable in the development and evolution of urban-rural integration.Although the correlation between each index variable of the Central Plains urban agglomeration and the degree of urban-rural integration is between 0.6 and 1,the correlation between the influencing factors of public services and urban-rural integration in each city is the lowest,but the correlation between specific indicators and the degree of urban-rural integration and indicators The relationship between the influencing factors represented and the degree of urban-rural integration is different.(3)There are certain commonalities and differences in the roles of related factors in promoting the development of urban-rural integration.The commonality means that the correlation between each index variable of the Central Plains urban agglomeration and the degree of urban-rural integration is between 0.6and 1.The correlation between the influencing factors of public services in various cities and the degree of urban-rural integration is the lowest,and the difference is reflected in the specific indicators and the degree of urban-rural integration.The degree of correlation and the degree of correlation between the influencing factors represented by the indicators and the degree of urban-rural integration are different,and each influencing factor plays a different role in the 9 cities.On the whole,industrial structure,population flow and ecological construction have an impact on urban-rural integration.Its role is higher than other aspects,and it plays a very important role in the process of urban-rural integration development,while public construction is the common shortcoming of urban-rural integration of nine cities in the Central Plains urban agglomeration.(4)There are differences in the driving force of various influencing factors in the process of driving the development of urban-rural integration.In the process of urban-rural integration,industrial structure is the core driving force of urban-rural integration;spatial layout is the catalyst of urban-rural integration;population mobility is the direct driving force of urban-rural integration;public services are the social regulation force;ecological construction is the foundation of urban-rural integration;policy It is the guarantee of urban-rural integration,and its formation mechanism is analyzed.(5)The urban-rural integration pattern of the Central Plains urban agglomeration has obvious differences.It is necessary to optimize the urban-rural integration spatial pattern of the Central Plains urban agglomeration from the aspects of integrating urban and rural industries,optimizing the spatial pattern of urban and rural areas,improving infrastructure connectivity between urban and rural areas,and improving the efficiency of resource allocation.
