Focusing on the issue of the ban on foreign garbage, this paper analyzes the impact of the ban on China from both qualitative and quantitative perspectives. By collecting before and after the trash ban of China, China’s imports of scrap metal, waste paper, waste plastics data and related producer price index. it is concluded by granger causality test model that under the 5% confidence interval, the waste imports less, the higher the related product producer price index; Secondly, based on nemero pollution evaluation model, this paper finds that the nemero score of water quality in China has decreased by 0.026 and the water quality has improved to some extent. The two models established in this paper are of great significance for analyzing the impact of the ban on foreign garbage on China and specifying corresponding measures.
