高速铁路建设与开通对福建县域经济贡献差异的双重差分法分析

Analysis of Differential Influence on Construction and Operational of High-speed Railway in county economy in Fujian Provice Based on Dual Difference Method

以2002-2018年福建省58个县市为例,利用双重差分法分别估计高速铁路的建设与开通对沿线有无开设站点县域经济的差异化影响.研究发现:高速铁路建设和开通能促进福建省内大部分县域经济的发展,且开通对沿线开设站点的县域经济的影响大于建设;主要线路在福建省内,且线路之间有序衔接的高速铁路的建设与开通均会带来显著的经济效益,而由多省共建的高速铁路的经济效益则有所区别;高速铁路的开通促进了经济发展,进一步拉大沿线县域的经济差距.

This paper took 58 counties in Fujian Province for samples to estimate differential influence on construction and operational of high-speed railway from 2002 to 2018.The dual difference method was used to estimate the differential impact of construction and operational of high-speed railway on the county economy with or without station along the line.The present study showed that construction and operational of the high-speed railway can promote the economic development of most counties in Fujian Province.The construction and operational of high-speed railway with orderly connection between main lines in Fujian Province will bring significant economic benefits,while the economic benefits of high-speed railway jointly built by many provinces are not obvious.The operational of the high-speed railway promotes the flow of economic factors,further widening the economic gap along the counties.
