In this paper, based on provincial panel data from 2005 to 2014 in China, a theoretical and econometric model was built, the provincial region internal agglomeration index and external agglomeration degree on market scale effect were constructed, and an in-depth empirical research on the spatial agglomeration of the impact of industrial pollution emissions intensity was studied. The main conclusions were as follows. Per unit of GDP industrial COD, industrial SO2 and industrial soot and dust pollution emissions intensity were reduced by spatial agglomeration; Internal agglomeration had a negative impact on the gap of industrial COD discharge, and the gap was reduced by it; External agglomeration had a positive impact, it was showed that the importance of location was more reflected in the correlation between different regions along with the enhancement of agglomeration externalities, namely market scale effect was strong; External agglomeration degree of region played a significant role in the effects of industrial pollution emissions intensity threshold effect.
