Regional difference decomposition and convergence pattern of nearby urbanization in China from 2000 to 2020
Nearby urbanization is a new urbanization development path relative to remote urbanization,which refers to the process in which the rural population migrates to small and medium-sized cities and towns near their home areas for employment and residence rather than to distant places.Under the background of new-type urbanization,the regional difference of nearby urbanization constitutes a significant part of China's overall regional urbanization disparities,and it will profoundly affect China's urbanization process and the coordinated development of the economy and society.In this study,we used Theil index nested decomposition and the spatial Markov chain model to analyze the overall difference and decomposition of China's nearby urbanization development,and describe the regional convergence pattern of China's nearby urbanization development in detail,focusing on the impact of spatial effects on the nearby urbanization.The results show that:1)From 2000 to 2020,the overall difference of nearby urbanization level in China showed a trend of continuous narrowing,consistent with the gradual narrowing of the development direction of the country's regional nearby urbanization gap.The overall difference of the urbanization rate within provinces was the largest,followed by the urbanization rate within counties,and the urbanization rate within towns was the smallest.2)From the perspective of scale decomposition,local urbanization and its three subtypes(provincial urbanization,county urbanization,and town urbanization)showed the largest differences within provinces.By comparing the inter-provincial differences in the four regions,the western region had the largest inter-provincial differences,while the other regions showed relatively small differences.Comparing the intra-provincial differences of the four regions,the differences in the western and central provinces were large,while the differences in the eastern and northeastern provinces were small.3)With regard to convergence patterns,there were spatial convergence clubs for nearby urbanization and its decompostions in China.The development of nearby urbanization in China showed obvious spatial linkage effect with the surrounding environment,and there was a certain spatial spillover effect.The results imply that the regional inequality of nearby urbanization in China follows the neoclassical convergence hypothesis and will narrow in the long term.Overall,the regional inequality of nearby urbanization in China from 2000 to 2020 stemmed mainly from inter-provincial inequality,especially in the central and western regions.With the improvement of the development level and radiation capacity of central cities in central and western China,we should strengthen support for the economic development of secondary regional node cities and improvement of public service facilities in small towns.This study provides a scientific support for comprehensively grasping the regional differences of urbanization in China and scientifically formulating the strategic measures of differentiated urbanization.
