Abstract: Since the reform and opening, industrialization has promoted the rapid growth of China’s economy. However, the industrial pollution made by industrial development has caused a great pressure on the environment and a series of environmental problems. The relationship between industrial scale and industrial pollutant emissions will be different due to the difference of regional development stage, industrial structure, technological level and pollution control. The total amount of industrial pollutant emissions in China is very different, and there exists an obvious mismatch between industrial pollutant emissions and industrial agglomeration level. This research focuses on the following questions: What is the spatial distribution of industrial agglomeration and industrial pollutant emissionsin China? What is their spatial correlation? By using the methods of gravity analysis of geographic concentration, spatial correlation, econometric model, and the data of 285 cities in China from 2003 to 2013, this article studied the spatial distribution characteristics and spatial correlation of industrial agglomeration and emissions of industrial wastewater and industrial SO2, and examined the role of industrial agglomeration level on industrial pollutant emissions. The main conclusions are as following: 1) The gravity center of industrial agglomeration and pollutant emissions is different in distribution, trajectory, distance and speed. The gravity center of industrial agglomeration level first shifted north and then southward. The gravity center of industrial waste water is moving southward. The industrial SO2 pollution shows the“S” movement trajectory. The gravity center of industrial agglomeration level moves longer and faster. 2) The industrial concentration level in the eastern region is higher than that in the middle and western region, and the intensity of industrial pollutant emissions is more prominent in the western and middle region. 3) There is a negative correlation between industrial agglomeration level and industrial pollutant emission intensity, there exists three types of spatial match between the level of industrial pollutant emission intensity and industrial agglomeration, which are high-low, low-high and low-low. 4) Industrial agglomeration is beneficial to reduce industrial pollutant emissions in the whole country and different regions. Industrial agglomeration has a greater effect on industrial pollutant emission reduction in the western and middle than in the east region. 5) To control industrial pollutant emission, China should continue to promote the industrial agglomeration and take different measures according to local conditions. In eastern China, efforts should be made to the control of the scale of industrial agglomeration, the optimizing of the industrial structure and the using of the positive externalities.The middle and western regions should further increase the concentration of industry, and promote the effect on emission reduction of technological spillover and technological advancements.
