Abstract:Based on the data of gross domestic product (GDP), total industrial output value, industrial wastewater, industrial waste gas and industrial solid waste, using the gravity model to calculate barycentric coordinates and offset distance, reveal the tracks and its changes of economic and industrial pollution gravity center of the Yangtze River Delta from 2000 to 2010. Furthermore, the paper explores the driving forces of the decoupling changes from four aspects, such as economic development, industrial structure, pollution transferring and environmental investment. The result shows that both economic gravity center and industrial pollution gravity center have being located in the northwest of region’s geometric center, but from the tracks, there is a certain decoupling phenomenon between them. The economic gravity center shifts to the northwest direction, the GDP gravity center and industrial gravity center have been respectively moving 9.45km and 7.58km to the northwest of the Yangtze River Delta. However, the industrial pollution gravity center shifts to the southeast direction, industrial wastewater, waste gas and solid waste gravity centers have been moving 18.11km, 28.92km and 3.84km respectively. Moreover, the economic gravity will still move toward northwest, in the contrary, the environmental gravity toward southeast in the near future.In detail, the decoupling phenomenon mainly attributes to the following aspects: Firstly, the economic structure optimization and unbalanced development aggravate the economic center of gravity move to the northwest. Secondly, environmental protection investment promotes the industrial pollution gravity center move to the southeast. Lastly, heavily industrial structure and pollution transferring between regions have sharpened the industrial pollution gravity center move to the southeastern of the Yangtze River Delta.
