Abstract: Based on the environmental statistics of 31 provinces (municipalities and autonomous regions) in China from 2005 to 2015, Using GIS spatial analysis method and SARAR econometric model, the temporal and spatial pattern of industrial wastewater discharge and the characteristics of spatial agglomeration are described, and their driving factors and regional differences are further revealed. The results showed that:（1）During the research period, the discharge of industrial wastewater decreased year by year, but the total amount of wastewater discharged continuously increased, indicating that the main source of wastewater discharge in China has been transformed.（2）China’s industrial wastewater discharge shows a spatial pattern of “southeast high and northwest low”, and Hu Huanyong line can be regarded as the dividing line between China’s industrial wastewater discharge “hot zone” and “cold zone”.（3）China’s industrial wastewater discharge has shown a clear spatial positive correlation, and spatial agglomeration trend increased year by year;（4）Estimates of SARAR model showed that urbanization rate, proportion of the secondary industry and number of resident population are main driving forces of China’s industrial wastewater discharge. Compared with the whole country, the SARAR model estimation results of the hot zone are basically the same as the above conclusions, but the effect of each driving force is slightly different
