【摘要】：利用三阶段DEA-Malmquist指数法,对2009~2014年长江经济带11省市水资源全要素生产率及其分解指数进行了测算和分析。研究结果表明:在剔除了外部环境因素和随机误差因素以后,长江经济带水资源的全要素生产率及其分解效率发生了显著变化,水资源全要素生产率年均增长7.2%,技术进步指数年均增长4.7%,技术效率指数年均增长2.4%,技术进步是推动长江经济带水资源全要素生产率增长的主要源泉。分区域来看,西部地区水资源全要素生产率和技术效率年均增长率最高,东部地区技术进步年均增长率最高。长江经济带水资源全要素生产率存在显著绝对β收敛,表明长江经济带内省际水资源全要素生产率差距正在缩小,最终都朝相同的稳态水平趋近。
[Abstract]:Based on the three-stage DEA-Malmquist index method, the total factor productivity and its decomposition index of water resources in 11 provinces and cities in the Yangtze River Economic Belt from 2009 to 2014 were measured and analyzed. The results show that the total factor productivity and decomposition efficiency of water resources in the Yangtze economic belt have changed significantly after excluding external environmental factors and random error factors. The annual growth of total factor productivity of water resources is 7.2%, the average annual growth of technological progress index is 4.7%, and the average annual growth of technological efficiency index is 2.4%. Technological progress is the main source of promoting the growth of total factor productivity of water resources in the Yangtze River economic belt. The average annual growth rate of total factor productivity and technical efficiency of water resources in the western region is the highest, and the annual growth rate of the technological progress in the eastern region is the highest. There is significant absolute 尾 convergence in total factor productivity of water resources in the Yangtze River economic belt, which indicates that the gap of total factor productivity of water resources among provinces in the economic belt of the Yangtze River is narrowing and eventually approaching to the same steady state level.
