Abstract: Open and sustainable development is the theme that underpins a country’s high-quality economic development. This study uses GMM regression, mediation effect test to conduct empirical tests based on the panel data of China’s industrial sectors from 2003 to 2015 to analyze the internal mechanism of the impact of intermediate product imports on China’s industrial pollution emissions. The results show that (1) Intermediate product imports can significantly promote the emission reduction of industrial wastes, including wastewater, waste gas and solid waste. (2) Considering the differences in the level of pollution intensity, this paper classified the sample and found the impact is heterogeneous that for the heavily, moderately, lightly polluted industries, intermediate product imports have different negative impacts on their pollution emissions. (3) Intermediate products imports reduce industrial pollution emissions through import competition effect, variety effect and technology spillover effect, and all of them play a partial mediating role.
