遂渝铁路建设与重庆县域经济发展研究

Research on the Construction of the Suining-Chongqing Fast Railway and the Economic Development of Chongqing County

通过收集2002-2008年遂渝铁路重庆沿线区级行政单元的平衡面板数据,将遂渝铁路开通作为一项良好的实验案例,运用双重差分模型来考察遂渝铁路开通建设对重庆沿线各区经济发展和产业结构水平的净影响。实证结果分析表明:从短期来看,快速铁路建设不仅能够推动沿线地域经济快速增长,还能促进其产业结构转型优化升级。平均而言,衡量产业结构的第三产业增加值高于沿线未开通站点区域0.702个百分比。为解决内生性问题的困扰,通过进行一系列的安慰剂检验,保证了结果的稳健性。

By collecting the balance panel data of district-level administrative units along Suining-Chongqing Railway in 2002-2008, the opening of the railway is regarded as a good experimental case, and the DID model is used to investigate the economic development of the railways along the Chongqing-based railway. And the net impact of the level of industrial structure. The analysis of empirical results shows that in the short term, rapid railway construction can not only promote the rapid growth of regional economy along the line, but also promote the optimization and upgrading of its industrial structure. On average, the added value of the tertiary industry, which measures the industrial structure, is higher than the 0.702 units in the unopened site area. In order to solve the problem of endogenous problems, a series of placebo tests were carried out to ensure the robustness of the results.
