Study on the impact of the Beijing–Shanghai high-speed railway on regional economic equity based on economic performance

Abstract

According to the panel data of stations along the Beijing–Shanghai high-speed railway (BSHR) from 2008 to 2018, the influence of BSHR on regional economy of cities along the line is analyzed, and the influence of the opening of the BSHR on regional economic equity of cities along the line, through constructing the difference-in-differences model. The research result shows that the opening of the BSHR greatly promotes the growth of the GDP per capita of the site cities along the line and the optimal allocation of resources, such as labor, information and technology, and accelerates the two-way flow of factors of production between big cities and small and medium-sized cities at stations along the high-speed railway, makes high-quality resources from small and medium-sized cities flow to big cities along the line, while some backward resources from big cities gradually tilt toward small- and medium-sized cities along the line. In short, the opening of BSHR promotes the economic growth of the cities along the line, shortens the economic gap between the cities, is conducive to realizing regional economic equity.

The Impact of the Urban Linkage Relations in the Beijing-Tianjin-Hebei Region in the New Era on Economic Development Based on the Gravity Model in the Context of Big Data

“…Specifically, there is linkage relationship between the economic and social level of a given region and other regions, or indicates the possibility of constructing economic and social relations. The measurement research based on spatial accessibility mainly includes Yu Huimin et al (2020) [13] , Jin Cheng et al (2012) [14] , Tian Ye et al (2018) [15] , Ma Lili et al (2021) [16] , Zhao Yun et al (2015) [17] . Most research on accessibility measurement is on the basis of the centrality of a given particle in a region, which only refers to the accessibility within the region; while simultaneously there is no doubt that there are some relatively novel frontier research among them, Chen Wei introduced spatial heterogeneity into the analysis framework and formed a realistic accessibility index based on the dimensions of continuity and compactness (Chen Wei, 2020) [18] .…”

Evaluating the barrier of typical production factor flow in the Chengdu-Chongqing Urban Agglomeration based on multi-source big data

“…When production factors cannot flow freely, economic cooperation between regions is reduced and more duplicative industries are built, thereby reducing overall economic efficiency (Wang and Yang, 2021). Promoting the free flow of production factors is an important way to improve resource allocation and realize the integrated development of the regional economy (Walz, 1997;Chu et al, 2018;Chen, 2020;Yang et al, 2022). Therefore, promoting the free flow of production factors is an important starting point to achieve high-quality development for China.…”
