基于PDA模型的中国水资源消耗及其政策影响因素研究
Research on policy influencing factors of water resource consumption in China based on PDA model
摘要
Abstract
This paper used panel data of three major industries in 31 provinces(or autonomous regions)of China from 2011 to 2020,applied the production theory decomposition method,and selected the non radial distance functions in the multi-level common frontier DEA model to analyze water resource consumption and its policy influencing factors in China.The results show that the western region is gradually becoming the second largest water consuming region in China,and the consumption of water resources in China is shifting from"one,two,three"to"one,three,two"industrial water consumption trend.Among the proposed new decomposition factors,industrial structure adjustment is more conducive to promoting the reduction of water resource consumption in the western region,regional balanced development is more conducive to the reduction of water resource consumption in the central region,and market-oriented reform is more conducive to promoting the reduction of water resource consumption in the eastern region.Among all the decomposition factors,technical efficiency has the most prominent contribution to reducing water consumption.Based on this,policy recommendations are proposed to accelerate industrial structure adjustment,enhance the positive impact of industrial digitization and greening on water resource utilization.关键词
