Abstract
Chengdu Chongqing high-speed railway will have a far-reaching impact on the economic and social development of the areas along the line. Based on the data of the regions along the Chengdu Chongqing high-speed railway from 2009 to 2019, taking the added value of the secondary and tertiary industries and the level of urbanization rate in each region as the explanatory variables, taking 2016 as the policy time node, this paper empirically tests the impact of the opening and operation of Chengdu Chongqing high-speed railway on the regional economic development along the railway by using the did double difference model estimation method. The results show that the opening and operation of Chengdu Chongqing high-speed railway has a significant negative impact on the secondary industry output value and urbanization rate along the line, reflecting the agglomeration effect of high-speed railway economy. Therefore, when formulating policies, small and medium-sized areas should strive to amplify the diffusion effect of high-speed railway.
