Analysis of China’s Agricultural Non-Point Source Pollution and Green Total Factor Productivity

Agricultural total factor productivity is an important indicator to measure and evaluate the quality of agricultural development and reform performance. Based on the panel data of 31 provinces and cities in Chinese Mainland from 2000 to 2017, this paper uses a comprehensive survey-based inventory analysis method to measure agricultural non-point source pollution in various regions, regards it as an undesired output, comprehensively uses common frontier technology and SBM (Slack Based Measure)Malmquist-Luenberger index model to measure the growth and decomposition of agricultural green total factor productivity, and builds a regression model to test the impact of urbanization on total factor productivity. The research shows: firstly, China's agricultural non-point source pollution has maintained a high emission intensity for a long time, especially in the west, which is significantly higher than other regions; from the perspective of sources, the contribution of livestock and poultry breeding exceeds 50%. Secondly, the average annual growth rate of China's agricultural green total factor productivity reaches 5.61% during the sample plate period, and the development trend is decreasing from the east to the middle to the west to the northeast. The main driving force for growth is the advancement of agricultural technology, and the efficiency of agricultural technology has shown a negative growth. Thirdly, the development of urbanization has a significant positive impact on the growth of agricultural green total factor productivity. Based on the conclusions of the analysis, this paper puts forward suggestions for transforming the production relations of small farmers, accelerating the process of urbanization, and promoting the green development of agriculture.
