The structural pollution has become one of the major features in our environmental pollution in recent years,which greatly affects the quality of economic development.

Based on the investigation of environmental and economic statistic data of China, the relationship between regional environmental quality and local economy-resources background was analyzed; the general situation of China structural pollution was investigated through comparison with several foreign countries.

This pollution structure's change has much to do with urban development and adjustment of industrial structure.
