高铁建设与中国城市规模分布扁平化

High-speedrail and city size distribution of China

考察高铁开通对中国城市规模分布的影响。研究发现,高铁开通显著地促进了东部地区城市规模分布的扁平化,但对全国以及对中西部地区则没有影响。采用多个替代的被解释变量和解释变量以及工具变量回归,均得到相对稳健的结果。研究结果为未来中国城镇化的道路选择提供了一定的依据。

This paper investigates the impact of high-speed rail(HSR)on the scale distribution of cities in China.Our empirical analysis finds that the opening of HSR flattens the scale distribution of cities in eastern China but has no significant effect on that of cities in western China and the country overall.This conclusion is robust by the checks of alternate variables and IV regression.This paper provides a theoretical foundation for the future path choice of urbanization in China.
