    摘要:

    使用2005—2014年长江经济带11个省(市)的面板数据,基于投入导向的超效率DEA-CCR模型,测算含有非合意产出的全要素工业水资源利用率,利用Malmquist指数对全要素工业水资源利用率进行分解,分析工业水资源利用率提高和降低的主要影响因素,对全要素工业水资源利用率进行收敛性分析,判断各地区工业水资源利用率差异的变化趋势。研究结果表明:不同省(市)工业水资源利用率差距明显,下游地区最高,中游地区最低;2005—2014年,长江经济带区域工业水资源利用率总体呈提高趋势;科技进步是推动全要素工业水资源利用率提高的主要因素;长江流域工业水资源利用率呈收敛趋势,省(市)工业水资源利用率差距在缩小。

    Abstract:

    Using the panel data of eleven provinces in Yangtze River economic zone from 2005 to 2014, the total-factor water resource use efficiency including undesirable goods is measured based on the input-oriented super-efficiency DEA-CCR model, and then, the water resource use efficiency is analyzed by using the Malmquist index. The main influencing factors for the increase and decrease of the total-factor water resource use efficiency are investigated, and the variation trend of the water use efficiency in various industrial regions is determined. The results show that the industrial water use efficiency in various provinces has large difference, and it is the highest in the downstream and the lowest in the middle reaches of Yangtze River economic zone. The water use efficiency of the whole economic zone has an increase trend from 2005 to 2014. The technical progress is the major power to promote the total-factor water resource use efficiency. The industrial water resource use efficiency of Yangtze River economic zone exhibits a convergent trend and, the gap among various provinces decreases.
