【摘要】：文章基于全要素和要素替代的思想,以单位水资源产出的实际值与最优值之比构建了水资源绩效指数,在考虑了污染排放约束的基础上,采用基于全局基准技术的非径向方向性距离函数模型(GBT-NR-DDF),测度了2001-2012年中国分省和分区域的水资源绩效,并对其演变趋势和驱动因素进行了实证考察。研究发现:(1)我国水资源绩效的整体水平偏低,样本期间全国水资源绩效指数的均值为0.3870,与理想值相比仍有61.30%的提升空间;(2)从八大区域来看,南部沿海和北部沿海地区的水资源绩效较高且呈现上升态势,东部沿海、东北地区和黄河中游地区的水资源绩效居中,长江中游、西南地区和西北地区的水资源绩效最低;(3)经济发展水平、COD减排力度和技术进步对水资源绩效的提升具有促进作用,水资源丰裕程度对水资源绩效有显著的负向影响。
[Abstract]:Based on the idea of total factor and factor substitution, this paper constructs the water resource performance index based on the ratio of the actual value to the optimal value of the unit water resource output, and takes into account the pollution emission constraints. The non-radial directional distance function model (GBT-NR-DDF) based on global benchmark technique is used to measure the performance of water resources in provinces and sub-regions of China from 2001 to 2012. The evolution trend and driving factors of this model are investigated empirically. The results show that: (1) the overall level of water resources performance in China is on the low side, the average of the national water resources performance index during the sample period is 0.3870, which is still 61.30% higher than the ideal value; (2) the performance of water resources in the southern coastal and northern coastal areas is relatively high and rising, while in the eastern coastal, northeast and middle reaches of the Yellow River, the performance of water resources is in the middle, the middle reaches of the Yangtze River, and the middle reaches of the Yangtze River. The performance of water resources in the southwest and northwest regions is the lowest; (3) the level of economic development, the intensity of COD emission reduction and technological progress can promote the performance of water resources, and the abundance of water resources has a significant negative impact on the performance of water resources.
