Abstract：IMeasuring the standard of regional integration in the Yangtze river delta is the basis of the transformation from qualitative analysis to quantitative analysis. On the basis of clarifying the connotation of regional integration in the Yangtze river delta, this paper constructs a comprehensive evaluation index system of the Yangtze river delta region, and sets up 36 basic indexes from six aspects, including space, economy, market, public service, ecology and politics, using the global principal component analysis method to measure and analyze the integration level of the Yangtze river delta from 1999 to 2017. Studies show that the integration level of the Yangtze river delta is steadily rising year by year, and Shanghai is in a pole position in the integration development. There is a large gap between Anhui and other provinces and cities in the Yangtze river delta region, showing obvious shortfalls, especially in the side of spatial integration, economic integration and ecological integration. In terms of secondary indicators, the degree of political integration and ecological integration in the Yangtze river delta is generally low.
