Abstract: Aiming at the quality green developing in Yangtze River economic zone, this paper uses water resource element as the core to study the impacts of water resource allocation on green efficiency development, and to clarity the roles of industrial structural adjustment during water resource element impacts green efficiency development. By means of 2003 to 2020 panel data, this paper uses super-efficiency SBM (slack-based measure) to estimate its green development efficiency and studies the impacts of three constraints, gross water resource, water use efficiency and water resource quality on green development efficiency in Yangtze River economic zone, and verifies the mediating effect and interaction of three industrial structural adjustment dimensions with water resource, industrial structural rationalization, sophistication and softening. Water use efficiency in water resource constraints positively plays a major role on its green development efficiency, deceasing from upper- to down-stream. Industrial structural softening plays a mediating role, and industrial structural sophistication also plays a mediating role during gross water resource impacts green development efficiency in the upper-stream. In the down-stream, both water use efficiency and water resource quality play a mediating role amid green development efficiency. In the entire Yangtze River stream an interaction exit among water use efficiency, industrial sophistication and softening, and between water constraint and industrial structural rationalization. Interaction prevails in the down-stream, it also exists between water use efficiency and industrial structural rationalization & softening, and between water constraint and industrial structural rationalization, sophistication & softening.

Key words: Yangtze River economic zone, water resource constraint, industrial structural adjustment, green development efficiency, mediation, interaction

摘要: 长江经济带是我国重要的水资源聚集区、水生态功能区,但是水环境污染和水资源消耗已成为其可持续发展的障碍。为推动长江经济带绿色高质量发展,本文旨在探究以水资源要素为中心考量长江经济带的资源分配如何影响绿色发展效率,同时厘清长江经济带产业结构调整在其水资源要素影响绿色发展效率过程中发挥的重要作用。论文基于2003—2020年面板数据,运用超效率SBM(slack based measure)模型测算绿色发展效率,分析水资源总量、用水效率和水资源质量三重约束对长江经济带绿色发展效率的影响,并检验了产业结构调整的3个维度,即产业结构合理化、产业结构高级化以及产业结构软化的中介效应及其与水资源约束的交互效应。结果表明:1)水资源约束中用水效率对长江经济带绿色发展效率影响最大,表现为正向促进作用,促进力度表现出上游>中游>下游的特征;2)从中介效应来看,长江经济带全流域主要是产业结构软化在用水效率影响绿色经济发展时发挥了中介作用,分流域来看主要是产业结构高级化发挥了主要作用,产业结构高级化在上游地区水资源总量影响绿色发展效率时表现出了中介作用,在下游地区用水效率、水资源质量影响绿色发展效率过程中也表现出了中介效应;3)从交互效应来看,长江经济带全流域用水效率与产业结构高级化、产业结构软化之间均存在交互作用,此外还存在水量约束与产业结构合理化的交互效应,分区域来看,下游是交互效应作用范围最广的地区,用水效率与产业结构合理化、软化之间以及水量约束与产业结构合理化、高级化、软化之间均存在交互作用。
