流域产业生态化效率的区域差异及影响因素分析——以金沙江为例

Analysis of Regional Differences and Influencing Factors of Eco-efficiency of River Basin Industry:A Case Study of Jinsha River

本文以2000-2016年金沙江流域的15个市(州)面板数据为基础,运用随机前沿分析法测算了金沙江流域产业生态化效率,并对其产业生态化效率的影响因素进行了实证研究。研究结果表明:金沙江流域产业生态化水平整体呈稳步上升趋势,产业生态化效率从0.45提升至0.62,金沙江流域各地区产业生态化效率差异逐渐缩小并趋于平衡。同时,地区经济水平、要素禀赋结构对产业生态化效率提高起着积极有效作用,而政府调控力度、产业结构、市场结构以及对外贸易依存度不同程度地阻碍了产业生态化发展。因此,树立全流域治理理念、建立区域联动发展机制、明确产业发展重点、建立严格的产业准入退出机制等,有利于推进金沙江流域产业生态化发展。

Based on the panel data of 15 cities(states)in the Jinsha River Basin from 2000 to 2016,the stochastic frontier analysis method was used to measure the industrial ecological efficiency of the Jinsha River Basin,and an empirical study was conducted on the factors affecting the industrial ecological efficiency.The research results show that the total industrial ecological level of the Jinsha River Basin has increased steadily,the industrial ecological efficiency has increased from 0.45 to 0.62,and the difference of the industrial ecological efficiency of each part of the Jinsha River Basin has narrowed and balanced.At the same time,the regional economic level and the factor endowment structure play an active and effective role in improving the industrial ecological efficiency,while the government’s regulatory efforts,industrial structure,market structure,and the dependence on foreign trade have hindered industrial ecological development to varying degrees.Therefore,establishing a basin-wide governance concept,setting up a regional linkage development mechanism,clarifying the focus of industrial development,and establishing a strict industrial access and exit mechanism are conducive to advancing the ecological development of the industry in the Jinsha River Basin.
