成渝高速铁路沿线区域经济发展影响实证研究

An Empirical Study on the Influence of Chengdu-Chongqing High-Speed Railway on Regional Economic Development

高速铁路的建设运营对沿线区域经济发展产生了广泛且深入的影响。基于成渝城市群的视角,综合运用面板回归预测模型、DID双重差分模型和加权平均旅行时间等方法,从实证角度分析了成渝高速铁路建设和运营对沿线区域经济发展的影响。实证分析结果表明:成渝高速铁路的建设对于不同沿线区域带来的经济影响存在差异,从整体上看,对沿线区域经济的第二产业产值和城镇化率影响显著,体现出高速铁路经济的扩散效应;成渝高速铁路的运营大幅提高了沿线所有区域的可达性水平,改善了大部分欠发达区域的经济空间结构,使沿线区域经济呈现均衡式发展态势。

The construction and operation of high-speed railway has a wide and deep impact on the regional economic development along the line.Based on the perspective of Chengdu-Chongqing city agglomeration, the impact of the construction and operation of Chengdu-Chongqing high- speed railway on the regional economic development along the route is analyzed from the empirical perspective by using the panel regression prediction model, DID double difference model,weighted average travel time and other methods.The analysis results show that the construction of Chengdu- Chongqing high-speed railway has different economic impacts on different regions along the line. On the whole, it has signi ficant impacts on the secondary industry output value and urbanization rate of regional economy along the line and re flects the diffusion effect of high-speed railway economy. The operation of Chengdu-Chongqing high-speed railway has greatly improved the accessibility level of all regions along the line and improved the economic spatial structure of most underdeveloped regions, making the regional economy along the line present a balanced development trend.
