“一带一路”已成为国家区域经济发展的重要战略布局,其中新丝绸之路经济带涉及我国东北、西北、西南12余省份,多为干旱内陆区,水资源已成为这些地区可持续发展的重要因素之一,提升水效率尤为重要。运用随机前沿分析(SFA)方法,以此12个省为研究对象,测算这些地区从2000-2013年的水资源禀赋效率、水资源利用效率、废水排放效率和综合水效率。结果表明,随着时间推移,这些省份的不同水效率均有所增长,但不同水效率均呈现地区差异。以此提出这些省份应该采取的节水和治理措施,为新丝路经济带绿色建设与水效率提升提供参考。
The Belt and Road has become an important strategic layout for the development of the national economy. The New Silk Road Economic Belt involves more than 12 provinces in northeastern, northwestern and southwestern China, mostly in arid inland areas, and water resources have become the sustainable development in these areas One of the important factors in the development of water efficiency is particularly important. Using SFA method, 12 provinces were selected as research object to calculate the water resource endowment efficiency, water resource utilization efficiency, wastewater discharge efficiency and comprehensive water efficiency in these areas from 2000 to 2013. The results show that over time, different provinces have different water efficiency increases, but different water efficiency shows regional differences. In this way, we should put forward water saving and treatment measures that these provinces should take to provide reference for green construction and water efficiency improvement of the new Silk Road Economic Belt.
