The Study Of Industrial Association In The Yangtze River Delta From The Correlation Analysis

Due to the change of global urban network development, China’s urban condensation and the Yangtze river delta concordance tenor is boosting, the connection in China’s economic city has a trend of increase. Of late years, the Yangtze river delta is among the most frequently choose scholars, although there has been many continuum models, measuring the ties between urban economic, but the majority of which is built on the use of indicators, like economic yield, urban population and the dist between the estimated economic, or choose a flow, commodity flow, cash flow, information flow to study the intimacy.The cluster analysis methods are used in order to perform a comparative study of16cities of the the Yangtze River Delta in relation with the fluctuations of the basic economic indicator. The statistical distances between cities are calculated for various moving time windows, and the time variation of the cluster structure is investigated.In consideration of the robustness of the MST,a complementary approach Moving Average Minimal Length Path (MAMLP) algorithm allows to search for a cluster-like structures derived both from the hierarchical organization of cities and from their relative movement inside the hierarchy. It is found that the strongly correlated countries with respect to GDP fluctuations can be partitioned into stable clusters. Some of cities display strong correlations.
