THE VARIATION CONTRASTIVE ANALYSIS OF ECONOMIC GRAVITY CENTRE AND REGIONAL POLLUTION GRAVITY CENTRE OF CHINA:1986—2006
利用1986-2007年省级GDP、工业总产值和污染数据，计算并对比中国经济重心与区域污染重心的移动方向、距离和空间关系，发现两者均向南移动且空间相关。
using the concept of gravity and China's provincial GDP, gross industrial output value, and regional pollution of 1986-2007, this article makes the quantitative analysis of the movement of China economic gravity and regional pollution gravity in calculation of economic focus of the spatial structure. The results of analyzing the characteristics of dynamic changes of the economy and regional pollution center of gravity, including the direction of movement ,distance and spatial relationship etc, is that all gravity move toward south China and spatial relationship is correlative.
