Abstract:

Agricultural water consumption accounts for the largest proportion of water resources consumption in China. It is of great significance to study the utilization efficiency of agricultural water resources to alleviate the crisis of water shortage in China. Considering the undesired output in agricultural production, the efficiency of agricultural green water resources is more valuable to study. This paper aims to measure the efficiency of agricultural green water use and its dynamic changes in China. The panel data of Chinese provincial administrative regions from 2010 to 2018 is used in paper. The panel three-stage DEA model and Malmquist index model are the research methods. The Malmquist index model is used to analyze the driving factors of efficiency change. The results show that: 1) the utilization efficiency of agricultural green water resources in Inner Mongolia, Hainan and Tibet is relatively high; 2) the growth rate of agricultural green water resources utilization efficiency in Jiangsu, Guangdong, Zhejiang and Shandong is relatively high in all provincial administrative regions. The average annual growth rate of agricultural green water resources utilization efficiency in Liaoning and Jilin is negative, and the agricultural green water resources utilization efficiency has decreased; 3) the agricultural green water resources utilization efficiency in the eastern China has increased obviously, and the average annual growth rate is the fastest among the three regions; the central region shows a fluctuating upward trend, while the western region is in a state of steady fluctuation. The driving factors of agricultural green water resources utilization efficiency in China can be divided into technological progress factors, economies of scale and management level factors. Technological progress factors can effectively improve the utilization efficiency of agricultural green water resources in China, which is the main driving force to improve the utilization efficiency of agricultural green water resources in China during the study period. The scale and management level factors have different effects on the utilization efficiency of agricultural green water resources in different regions. The factors of scale economy and management level, together with the factors of technological progress, have promoted the improvement of the utilization efficiency of agricultural green water resources in the eastern region, and the management level factors have promoted the improvement of the utilization efficiency of agricultural green water resources in the western region. However, it inhibited the improvement of the utilization efficiency of agricultural green water resources in the central region. Better communication between regions and industries can eliminate inefficiencies in agricultural production management.

Key words: undesirable output, green water resources utilization efficiency, panel three-stage DEA, Malmquist index
