综合运用统计分析与ESDA方法,选取人均服务业增加值为测度指标,系统分析了江苏省县域服务业发展水平的时空格局演变。结果表明:1992年以来江苏省县域服务业发展水平的绝对差异呈扩大趋势,而相对差异趋于缩小,区域内服务业发展水平时间差异较大;从空间格局的演变过程来看,县域服务业发展水平呈现显著的空间正相关,即在空间上集聚分布,且集聚趋势有所增强。此外,服务业发展水平呈现明显的空间分异格局,苏南地区发展水平较高,苏北地区发展水平较低,沿江地区发展水平明显高于沿海地区。在此基础上,分析了江苏省服务业空间格局演变的影响因素。 By synthetically using statistical analysis and ESDA method, the per capita value added of service industry is selected as the measurement index to systematically analyze the spatial and temporal evolution of the service level of county in Jiangsu Province. The results show that the absolute difference in the development level of service industries in counties in Jiangsu Province has been expanding since 1992, while the relative differences have tended to narrow. There is a big difference in the development level of service industries in the region. According to the evolution of spatial patterns, county service industries The level of development showed a significant spatial positive correlation, that is, the spatial distribution of agglomeration, and the trend of agglomeration increased. In addition, the level of development of the service industry shows a distinct pattern of spatial differentiation. The level of development in southern Jiangsu is relatively high. The level of development in northern Jiangsu is relatively low. The level of development in the area along the Yangtze River is significantly higher than that in the coastal areas. On this basis, the paper analyzes the factors that affect the evolution of the service space in Jiangsu Province.
