长江经济带生态效率提升的空间计量分析——基于金融集聚和产业结构优化的视角

Spatial Econometric Analysis of the Eco-Efficiency Promotion of the Yangtze River Economic Zone: From the Perspective of Financial Agglomeration and Industrial Structure Optimization

长江经济带的战略地位进一步强化,绿色发展上升为国家战略,生态效率的提升促进绿色发展。文章探讨了金融集聚、产业结构优化对生态效率的提升作用,运用空间计量方法检验了金融集聚、产业结构优化和生态效率的空间自相关性,建立空间计量模型。主要发现有:生态效率存在空间集聚效应,不存在空间溢出效应;金融集聚对生态效率的提升作用不大,暗示着需要加强金融支持绿色产业和环境保护力度;产业结构优化对生态效率提升作用明显,贡献度较高。最后根据实证研究结论提出了相应的对策建议。

As the strengthening strategy of the Yangtze River Economic Zone and the national strategy of Green Development become reality, eco-efficiency promotion will improve the level of Green Development. From the perspective of financial agglomeration and industrial structure optimization promoting eco-efficiency, the paper tested the spatial autocorrelation of financial agglomeration, are structure optimization and eco-efficiency using spatial econometric methods and then established spatial econometric model. The main findings are： spatial agglomeration effect does exist for eco- efficiency while spatial spillover effect does not; financial agglomeration has a little influence on eco-efficiency, which implies the need to strengthen financial support for green industry and environmental protection; industrial structure optimization does promote eco-efficiency significantly, and it performs higher contribution to the later. Finally, it brings out the corresponding countermeasures and suggestions based on empirical findings.
