Research on the spatial differences and influencing factors of integrated urban-rural development in the Yangtze River Delta

Once the integrated urban-rural development enters a high-quality stage, multiple dimensions would be reflected in population, space, economics, society, and environment, which will further advance sustainable development. An urban rural have shown different features, rules, models amid social systems stages. Therefore, it's urgent to scientifically measure integration level of areas, revealing spatial differences, characteristics, internal mechanism. Targeting 41 cities within Yangtze River Delta, this paper evaluates area based on global principal component analysis, explores its agglomeration evolution pattern by ESDA method, analyzes factors that result differences Delta their interactive relations geographical detector, discusses regional between those influencing weighted regression method. The results indicate (1) is not balanced there great difference cities. (2) has apparent feature agglomeration, or other words, central become forces drive neighboring (3) Since influenced economic development, basic infrastructure, government support, industrial structure, all regions should put forward suggestions for formulation policies accordingly realities.
