南水北调增量供水的区域利益增进

Promotion of Regional Benefits of the Incremental Water Supply in the South-North Water Transfer Project

南水北调工程调水能够有效缓解缺水地区的缺水情况,为受水区带来经济、社会和环境效益。本文以南水北调中线工程调水量分配方案中的分水量为基准,以南水北调中线工程河南受水区11城市为案例,分析增量供水给各受水城市带来的利益增进。实证研究表明,水量分配的影响因素、水量分配的方法以及具体的水量分配方案,都会影响受水区之间的利益增进程度。基于南水北调中线工程调水量分配方案的调水利益表现出非均衡性,原来发展程度较高的城市在调水中会获得更多的利益、更好的发展条件和机会,其竞争优势将会得到进一步强化,南水北调增量供水在受水城市之间形成了基于调水的非均衡利益分配格局。

This paper estimates the contribution to regional benefit promotion ot the incremental water supply and then analyses the distribution pattern of regional benefits based on the allocation scheme in the Middle Route Project of South-North Water Transfer. Empirical studies have shown that the contribution to the regional benefit promotion of the incremental water supply, which is determined by the allocation programs of SNWT, is non-balanced. Cities with higher levels of development will get more benefits and better conditions and opportunities for development, and their competitive advantages will be further strengthened. So, a non-balanced distribution pattern of regional interests will be formed among different cities.
