利用中国2011-2020年31个省(自治区、直辖市)三大产业面板数据,基于生产理论分解方法,选取多层级共同前沿DEA模型中的非径向距离函数,对中国水资源消耗及其政策影响因素进行了分析.结果表明,西部地区正逐渐成为中国第二大水资源消耗区域,且中国水资源消耗从"一二三"向"一三二"的产业用水态势转变;在提出的新分解因素中,产业结构调整、区域均衡发展和市场化改革分别有助于减少西、中、东部地区的水资源消耗;在所有的分解因素中,技术效率对减少水资源消耗的贡献最为突出.提出了加快产业结构调整、提高产业数字化和绿色化对水资源利用的正向影响等政策建议.
Research on policy influencing factors of water resource consumption in China based on PDA model
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.
