摘要:

提高工业水资源效率既是缓解水资源短缺的重要举措,也是促进工业绿色转型升级的内在要求。在全要素生产框架下,本文基于绿色发展内涵构建共同前沿与群组前沿函数模型,分析2000—2018年工业绿色全要素水资源效率的时序变迁特点,并对群组前沿下的工业绿色全要素水资源效率进行空间收敛效应检验。结果表明:①不同地区工业绿色全要素水资源效率存在显著差异,在共同前沿下,效率整体上呈现“东部领先、中部追赶和西部落后”的空间格局;而在群组前沿下,效率测度过程能够克服共同前沿中总样本估计偏差的弊端,从而更为真实地反映效率实际变化,尤其是在东、中部地区效率均值排序中表现更为明显;②东部地区技术落差比最高(98.9%),与共同前沿最接近,中、西部地区技术落差比相对较为接近,但都显著低于东部,而多数地区效率均值低于0.65,说明工业节水减排依然具有较大提升潜力;③从空间收敛性来看,全国和中、西部地区效率均表现出σ收敛和绝对β收敛的特点,而东部地区存在内部效率差距逐渐被扩大的可能性;另外,全国和东、中、西部地区效率都具有条件β收敛的趋势,其中,加快产业结构调整,促进节水减排技术创新和提高环境规制质量尤为迫切。研究结果可为不同区域制定差异化的工业水资源效率驱动策略提供科学依据。

Abstract:

Improving the efficiency of industrial water resource use is not only an important way to alleviate water shortages, but also an inherent requirement for promoting industrial green transformation and upgrading. Hence, under the framework of total factor production, the common frontier and group frontier function models were constructed based on green development theory, and then the characteristics of temporal change of industrial green total factor water resource efficiency was analyzed. Furthermore, the spatial club convergence effect of industrial green total factor water resource efficiency under the group frontier was tested. The results show that: (1) There are significant differences in the efficiency of industrial green total factor water resource in different regions. Under the common frontier, the average efficiency presents a spatial pattern of “the east is leading, the central is catching up, and the west is lagging behind”. But under the group frontier, the efficiency measurement process can overcome the influence of the total sample estimation deviation under the common frontier, and then reflect the change of efficiency more realistically, especially in the ranking of the mean efficiency in the eastern and central regions. (2) The eastern region has the highest technology gap ratio (98.9%), which is closest to the common frontier, and the technical gaps of the central and western regions are similar but significantly lower than that of the eastern region, and the average efficiency of most regions is lower than 0.65, indicating that industrial water saving and emission reduction still have great potential for improvement. (3) From the perspective of spatial club convergence, the efficiency of the whole country and the central and western regions all show the characteristics of σ convergence and absolute β convergence, while the eastern region has the possibility of gradually widening the internal efficiency gap. In addition, the efficiency of the country and the eastern, central and western regions all have a trend of conditional β convergence. Among them, it is particularly urgent to accelerate the adjustment of industrial structure, promote technological innovation in water saving and emission reduction, and improve the quality of environmental regulations. The research results can provide a scientific basis for the development of differentiated industrial water efficiency driving strategies in different regions.
