黄河流域产业结构高级化与生态效率的耦合路径识别及空间治理

Coupling Path identification and Spatial Governance of Industrial Advancement and Ecological Efficiency in the Yellow River Basin

摘要:

探究产业结构与生态效率的协同发展问题对黄河流域生态保护与高质量发展具有重要意义。首先运用包含非期望产出的超效率SBM-DEA模型测算生态效率，着重考察水污染与水土流失治理效果；其次应用扩展的耦合模型研究了黄河流域产业结构与生态效率的耦合协调关系，并根据相关耦合特征对流域各省进行多重分类，设计了产业结构与生态效率升级的耦合路径；最后从耦合协调空间重心视角出发，研究了其迁移路径。研究发现：黄河流域各省产业结构与生态效率水平总体不高，空间上呈现从西南向东北递增的态势，省域差异较为显著；省域耦合协调水平呈阶梯化，在时序上表现为“U”型特征，在2010年左右出现拐点，与“十二五”规划的实行相契合；2011年之后，耦合协调重心持续向南转移，表明黄河流域南部各省在“十二五”及“十三五”期间有较好的协调发展表现。最后提出了关于黄河流域产业结构提升与生态治理的政策建议。

Abstract:

It is of great significance to explore the coordinated development of industrial structure and ecological efficiency for the ecological protection and high-quality development of the Yellow River Basin. The super-efficiency SBM-DEA model containing undesired output is used to measure ecological efficiency, and focus on the effects of water pollution and soil erosion control; second, the extended coupling model is used to study the coupling and coordination relationship between the industrial structure and ecological efficiency of the Yellow River Basin , and design the coupling path for upgrading the industrial structure and ecological efficiency according to the relevant coupling features multiple classifications of the provinces in the basin; finally, the paper studies the migration path from the perspective of the space gravity center of the coupling coordination. Through the research, it is found that: The industrial structure and ecological efficiency of the provinces in the Yellow River Basin are generally not high, and they are increasing spatially from the southwest to the northeast with conspicuous provincial differences. The provincial coupling and coordination level is in ladder shaped transformation, showing a "U"-shaped characteristic from time series perspective. With a turning point around 2010, which is consistent with the implementation of the "12th Five-Year Plan". After 2011, the focus of coupling coordination continued to shift to the south, indicating that the southern provinces of the Yellow River Basin had a better coordinated development performance during the "12th Five-Year Plan" and "13th Five-Year Plan". Finally, policies to improve the industrial structure and ecological management of the Yellow River Basin are presented.
