长三角地区城乡融合发展水平、演化及影响因素

在城乡发展差距日益扩大的背景下,以长三角地区作为研究案例,运用熵值法计算长三角地区2008—2018年城乡融合发展指数,并利用地理探测器模型分析城乡融合水平的主要影响因素及其演变特征。结果表明：长三角地区城乡融合发展水平呈现出“高低高”结构向“Σ”转变的空间演变特征,空间融合发展水平和社会融合发展水平的高值区大致呈现出“Σ”的空间分布特征,经济融合发展水平呈现出“高低高”的圈层结构特征,生活融合发展水平大致呈现出西高东低的空间分布格局;从地理探测器模型结果来看,经济发展水平、产业高级化、财政支农支出比例、财政分权有助于城乡融合的发展,经济发展的速度、产业结构偏离、城乡基本建设支出比例不利于城乡融合的发展;从时间变化上看,政府力量在逐步减弱,市场力量在逐渐增强。

The development level,evolution and influencing factor of urban-rural integration in the Yangtze River Delta

In the context of the growing gap between urban and rural development, this paper takes the Yangtze River Delta region as a research case and uses the Entropy method to calculate the development index for the 2008-2018 urban-rural integration and spatial integration, economic integration, social integration and lifestyle integration. And then it uses the Geographic Detector Model to analyze the main influencing factors and evolution characteristics of the level of urban-rural integration. The results show that the development level of urban-rural integration in the study region is characterized by spatial evolution from the "high-low-high" structure to a "Σ"-shaped pattern; from the perspective of the spatial characteristics of the urban-rural integration subsystem, the high value of the development level of spatial integration and the level of social integration presents the spatial pattern of a "Σ" shape, the economic integration development level is characterized as high and low circle structure, and the life integration development level roughly presents the spatial pattern of high in the west and low in the east. Seen from the results of the geographic detector model, the level of economic development, industrial advancement, the proportion of fiscal expenditures on agricultural support, and fiscal decentralization are conducive to the development of urban-rural integration; while the speed of economic development, the deviation of industrial structure, and the proportion of urban-rural infrastructure expenditures are not conducive to the urban-rural integration. From the temporal perspective, government power is gradually weakening, and market power is gradually intensifying.
