The effect of Import Solid Waste Ban on China’s Economy and Environment based on Grey Prediction Model

Abstract

In order to explore the impact of imported solid waste ban on China's economy and environment, a grey prediction model was established in this paper. GDP, comprehensive income from the utilization of waste resources, the number of imported solid waste treatment enterprises, and the discharge of polluting waste gas and waste water were selected as the indicators to measure the economy and environment. The model was used to predict the data of the unreal garbage ban and compare it with the data after the actual implementation, and get the proportion of the impact on China's economy and environment after the introduction of the policy. The results showed that before and after the promulgation of the ban on foreign waste, China's environmental pollution had improved significantly, the total exhaust gas emissions have been reduced by 34.1%, and the number of imported waste enterprises had decreased by 66.1%, stimulating the rise of the domestic waste utilization industry, and the overall domestic economy had grown steadily.
