摘要:

基于可变资本折旧率和考虑非合意产出的SBM模型,本文分别估算了中国省级水利设施资本存量和水资源利用效率。并在控制水资源利用结构、政府管制度等变量基础上,运用Tobit空间杜宾计量模型(Tobit-SDM)实证分析了中国2002—2016年省级面板数据,以探究水利设施对水资源利用效率的空间影响。分析发现:① 水利设施对水资源利用效率的影响存在明显滞后性,且呈“倒U型”;② 中国水利设施水平尚处于“倒U型”曲线左侧,即水利设施通过改善地区间水资源配置与降低非合意产出,提高了本地区与其他地区的水资源利用效率,呈现显著正向直接影响与溢出效应。基于此,本文认为地区水利设施建设需置于更广阔的视角,实现区域配套与协同,避免重复或过量的投资与建设,充分利用水利设施的溢出效应。此外,依靠优化产业配置实现水资源利用效率内生增长也是可行措施。

Abstract:

Based on the variable capital depreciation rate (capital depreciation rate changes with time, space, and specific infrastructure) and the SBM model considering unsatisfactory output, the capital stock and water resource utilization efficiency of China's inter-provincial water conservancy facilities were estimated in this study. On the basis of controlling variable such as the structure of water resources utilization and government regulation, this paper implemented a Tobit Spatial Dobbin Econometric Model (Tobit-SDM) to analyze the provincial panel data of China from 2002 to 2016 and explore the spatial impact (direct influence and spillover effect) of water conservancy facilities on water resources utilization efficiency. It is found that: (1) the impact of water conservancy facilities on water resources utilization efficiency was obviously lagging behind, and it exhibited an "inverted U type". (2) the level of water conservancy facilities in China is still on the left side of the "inverted u-shaped" curve, i. e. , water conservancy facilities improve the allocation efficiency of water resources among regions, reduce the unsatisfactory output of water resources utilization, and improve the utilization efficiency of water resources in the local region and other regions. In other words, the impact of water conservancy facilities demonstrates a significant positive direct influence and spillover effect. Based on the conclusions above, it is believed that the construction of regional water conservancy facilities needs to be placed in a broader perspective, to achieve the support and coordination of regional construction, to avoid duplication or excessive investment and construction, and to make full use of the spillover effects of water conservancy facilities. In addition, it is also a feasible measure to optimize the industrial allocation and realize the rational allocation of water resources to promote the endogenous growth of water use efficiency.
