黄河流域环境规制、区域污染转移与技术创新的空间效应

Spatial Effects of Environmental Regulation,Regional Pollution Transfer and Technological Innovation in the Yellow River Basin

采用黄河流域79个城市空间面板数据,以区域污染转移为中介,分析环境规制对技术创新的"本地-邻地"空间效应。实证结果表明:第一,环境规制与本地、邻地技术创新的关系均呈现出倒U形特征,并且邻地效应在较远距离上持续显著,表明黄河流域生态保护和高质量发展战略实施的必要性与科学性。第二,伴随本地环境规制强度提高,污染产业会发生区域转移,短期内邻地产业承接会提高其收入水平,促进技术创新;但长期会影响区域发展模式,最终导致邻地技术创新受到抑制。第三,实现黄河流域全局高质量发展需要中央政府进行科学顶层设计,绿色考核指标在实现生态保护目标同时,也有利于技术创新。

Based on the spatial panel data of 79 cities in the Yellow River Basin and the intermediary of regional pollution transfer,this paper analyzes the mechanism of environmental regulation on the"local-neighboring"spatial effect of technological innovation.The are following empirical results:Firstly,the relationship between environmental regulation,technological innovation of local and neighboring areas shows inverted"U"features,and the adjacent area effect continues to be significant in a long-distance,indicating the necessity and scientific nature of the implementation of ecological protection and high-quality development strategy in the Yellow River Basin.Secondly,with the improvement of the intensity of local environmental regulations,polluting industries will undergo regional transfers.In the short term,the undertaking of neighboring industries will increase their income levels and promote technological innovation,but it will affect the regional development in the long run,resulting in the suppression of neighboring technological innovation.Thirdly,the realization of the overall high-quality development of the Yellow River Basin requires the central government to carry out top-level scientific design.The green assessment indicators are not only achieve the goal of ecological protection,but also conducive to technological innovation.
