Study on the dynamic trajectory of industrial gravity center of the leading industry of the Yangtze River Delta from 1999–2012

With the escalation of the industrial structure, what the future of the Yangtze River Delta manufacturing will be, how the Yangtze River Delta to adjust the industrial structure to maintain good economic growth has become a community of common concern. This paper first uses principal component analysis (PCA) to identify the leading industry of the Yangtze River delta, and chooses three representative industries, namely the black metal smelting and rolling processing industry, general equipment manufacturing and computer and communication equipment manufacturing industry, to analyze the dynamic variation characteristic of the gravity centre of the leading industries from variation direction, distance by building industrial gravity center model. At last, we contrastively summarize the dynamic variation characteristic of the gravity centre of the leading industry of the Yangtze River Delta.
