摘要
京津冀协同发展是中国区域发展的重大战略,在实践层面取得了显著的进展,因而进行理论研究与总结具有重要意义。本文在"新"新经济地理学的框架内,构建了包含环境外部性的理论模型,研究发现随着运输成本的下降,产业分布会先由分散状态转变为聚集状态,再由聚集状态转变成分散状态,高效率企业具有更强的流动能力;环境污染是一种分散力,会阻碍聚集的出现,降低聚集程度;污染的空间溢出是一种聚集力,会增加聚集程度。本文又进一步将模型扩展为包含了区域差异的三区域模型,验证了模型结论的稳定性。本文理论模型的结论,为京津冀发展中出现的问题提供了理论解释,并为京津冀协同发展的政策提供了理论支撑。
The coordinated development of Beijing,Tianjin with Hebei is an important strategy of China's regional economy,and remarkable achievements. Therefore,it is of great significance to carry out the theoretical research.Based on the framework of new new economic geography,this paper built a theoretical model including the environmental externality. It is found that as transportation cost decreasing,economic activity will concentrate into the core region,and then disperses. And high efficiency enterprises have a stronger ability to relocate. The pollution is a kind of dispersion force,which will hinder the agglomeration and reduce the degree of agglomeration. However,spatial spillover of pollution is a kind of aggregation force,which will promote agglomeration. In this paper,the model is also extended to a three-region model including regional differences,and the stability of the model conclusion is examined.These conclusions provide a theoretical explanation for the Beijing,Tianjin and Hebei issues,and provide theoretical support for the coordinated development of Beijing,Tianjin and Hebei.
