长江经济带新型城镇化协调性的空间差异与时空演化

从城乡、产城、区域和城镇化与资源环境协调发展4个方面建立指标体系,衡量长江经济带105个地级及以上市新型城镇化的协调性,并运用泰尔系数和探索性空间分析考察协调性的空间差异和时空演化,结果发现:长江经济带新型城镇化协调性存在明显的反地势分布和"城市圈俱乐部"特征;东、中、西部城镇化协调性差异随时间越来越明显,东部城市主要体现在非省会城市之间的差异,中部主要体现在省会城市与非省会城市的组间差异,西部主要体现在省会城市之间以及省会城市和非省会城市之间的组间差异;长江经济带新型城镇化协调性表现出正的全局空间自相关,协调性高的区域开始集聚在一起,这种趋势随时间不断增强并且空间溢出效应明显。

STUDY OF THE SPATIAL DEFFERENTIATION AND SPATIAL TEMPORAL EVOLUTION OF THE COORDINATION OF THE YANGTZE RIVER ECONOMIC BELT'S NEW URBANIZATION

Using the index system made up with the integration of urban and rural areas' development, the coordination of the city and its industry, the balance among different regions, the coupling of the urbanization and the eco-environment, we performed a case study of the coordination of the new urbanization of 105 Cities of the Yangtze River Economic Belt. By using the Theil Index and the ESDA methods, we found that, 1. An inverse-topography distribution and an obvious "metropolitan-club" feature were founded. 2. Prominent differences were found between the eastern, mid, and western areas of the Yangtze River Economic Belt, and they becomes bigger with time. The main differences in the eastern areas are contributed by the differences of the non-capital cities, the main differences in the mid areas are contributed by the differences between the capital and non-capital cities, the main differences in the western areas are contributed by the differences in the capital cities and the differences between the capital and non-capital cities. 3. A significant positive spatial correlation was found, which means the high coordinated areas turn to gathered, and the trends becomes stronger belong time, at the same time, the space spillover effect was also founded.
