工业绿色水资源效率动态演进与空间溢出效应研究——以长江经济带为例

建立考虑非期望产出的EBM超效率模型测度2002—2018年长江经济带11个省市以及上、中、下游三大区域的工业绿色水资源效率，利用Kernel-Density估计方法考察该时段区域工业绿色水资源效率的核密度曲线，最后，在通过面板数据适应性检验的基础上运用固定效应下的空间杜宾模型对长江经济带工业绿色水资源效率进行计量，并对其时空异质性进行分析。研究发现：1）工业绿色水资源效率在不同省市具有明显的空间差距，体现在下游地区的效率显著高于中游和上游地区；2）工业绿色水资源效率（IGWRE）有显著的空间溢出效应，对邻近省市均具有空间集聚特征；3）通过效应分解得知经济发展程度、工业发达程度、经济进步、环境规制、产业结构、社会投资、对外开放水平以及交通基础设施有显著的直接和间接效应。

DYNAMIC EVOLUTION AND SPATIAL SPILLOVER EFFECT OF INDUSTRIAL GREEN WATER RESOURCE EFFICIENCY (IGWRE) BASED ON A CASE STUDY OF YANGTZE RIVER ECONOMIC ZONE

This paper uses a non-expected output EBM ultra-efficiency model to measure the industrial green water resource efficiency of 11 provinces and upper-, middle- and down-stream of Yangtze river economic zone during 2002 to 2018, and employs Kernel-Density to estimate the core density curves, and applies spatial Dubin model under fixed effect to calculate the industrial green water resource efficiency of Yangtze river economic zone on the basis of panel data adaption check, and analyzes its temporal-spatial heterogeneity. The industrial green water resource efficiency varies obviously in different provinces/cites, much higher in down-stream than middle- and up-stream. IGWRE is of outstanding spatial overflow effect, with spatial concentrating in nearby provinces/cities. Decomposition of effect suggests that IGWRE is, directly and indirectly, related to economy, industry, environmental regulations, industrial structure, social investment, foreign openness level and infrastructures.
