Analysis on Endogenous Mechanism of Metropolitan Area in Stimulating the Regional Economic Growth:Based on the Metropolitan Area of Jing-Jin-Ji,Yangtze River Delta and Pearl River Delta
使用断点回归设计，基于2003-2007年京津冀、长三角和珠三角都市圈数据，分析都市圈形成对区域经济增长的正面影响及其内生机制，发现该效应由蒂伯特机制和城镇化率提升驱动，且存在异质性：北京未能作为增长极提升京津冀经济绩效，而长三角和珠三角受益于其增长极。
This paper uses the regression discontinuity design to analyze the overall economic performance of the metropolitan area and its endogenous mechanism in spurring the regional economic growth based on the metropolitan area data of Jing-Jin-Ji,Yangtze river delta and Pearl river from 2003 to 2007.It is well-known that the formation of metropolitan area is based on the distance between one area and the central city,so that the distance is the key determinant of whether one area is a part of the metropolitan area or not.As a result,we can compare the samples beside the threshold of metropolitan area to determine the causal relationship among different variables.The empirical result shows that such positive effect of the metropolitan area formation on economic performance of metropolitan area is driven by the Tiebout mechanism and the enhancements of the urbanization rate.Furthermore,the influence of the metropolitan area formation is heterogeneous.Specifically,Beijing cannot act as a growth pole to improve the economic performance of the Jing Jin-Ji area.On the contrary,the area of Yangtze river delta and Pearl river delta have benefited a lot from theirs growth pole.
