Abstract:

Based on the national strategy of Yangtze River Delta economic integration and regional coordinated development and after measuring the urbanization coordination level of 41 cities in the Yangtze River Delta from 2001 to 2016, this study analyzed the spatial characteristics and formation mechanism of the coordinated development of urbanization in the Yangtze River Delta by using the methods of Theil Index, center of gravity track, hotspot analysis, and spatial econometric model. The results show that: 1) the overall difference of urbanization coordination level in the Yangtze River Delta is fluctuating and decreasing, and intra-provincial differences are shrinking while the difference between the provinces is expanding; the spatial distribution of the coordination level of urbanization in the Yangtze River Delta is generally higher in the east and lower in the west. The pattern of coordinated development of urbanization has experienced little change in the northwest-southeast direction and the center of gravity is relatively stable over the years, but the spatial correlation scope and dispersion degree are expanding. 2) According to the characteristics of spatial agglomeration, there is a significant positive spatial autocorrelation in the coordination level of urbanization in the Yangtze River Delta. The hotspots are gradually converging to the economically developed areas such as Shanghai, Southern Jiangsu, and Northern Zhejiang. The cold spots are stably distributed in Northern Anhui, Southern Anhui, and southern Zhejiang. 3) All factors that affect the spatial characteristics of coordinated development of urbanization are significantly positive. The level of economic development still dominates coordinated regional development of urbanization. Population agglomeration is more obvious for the improvement of the level of coordinated development of urbanization of neighboring cities. Giving full play to the driving role of the highly coordinated area of urbanization will realize the balanced development of the Yangtze River Delta.
