Spatial Interaction Effect of Nonpoint Source Pollution and Economic Growth on Agriculture Using Kuznets Curve and Grey Correlation Analysis

Abstract

This study used the environmental Kuznets curve to assess the link between regional growth in the economy and several types of agricultural nonpoint source pollution. To protect the environment in China, prevention of nonpoint source pollution and agricultural control are essential. In agriculture, nonpoint source pollution is mostly produced by improper usage of agricultural production components such as chemical fertilizers and plastic films. This paper aims to investigate the interacting effects of agricultural nonpoint source pollution and the economics of agricultural growth space to achieve synchronized growth of environmental atmosphere and agricultural economy. To evaluate agricultural nonpoint source pollution completely, the production coefficient technique and the equal standard pollution load approach are utilized. The Kuznets curve is used to verify the interaction impact between agricultural nonpoint sources and each person’s agricultural gross production value. Grey correlation analysis was utilized for further verification to increase the efficacy of verification of interaction effect between the two parameters. Experiments show that the proposed method has a good fitting effect and is easily implementable. It serves as an effective resource for future agricultural research and encourages the green development of agriculture.
