Impact of "Star-Type" High-speed Railway Network on High-quality Development of Regional Social Economy
This paper focuses on the first"Star-type"high-speed railway network in China and analyzes its impact on regional high-quality development from four dimensions:spatial pattern,economic development,social development and ecological environment.The study constructs a comprehensive impact evaluation model and establishes a multidimensional indicator system to evaluate the effects.It culminates in a detailed quantitative analysis of the outcomes to provide a nuanced understanding of the impacts.The result indicates that the opening of the"Star-type"high-speed railway network has significantly reduced the weighted average travel time between and within Henan province to 4.90 hours and 1.62 hours,with improvements rate of 65.6%and 37.8%.The intensity of regional connections has been significantly enhanced,gradually forming a"center-periphery"development structure which focuses on intra-provincial connections and steadily expands to the energy consumption optimization and comprehensive operational emission reduction of railway northeast and southeast.The primacy index of Zhengzhou high-speed railway hub has increased from 1.90 to 2.83,further consolidated its position as a core hub.The difference-in-differences model is used to verify that the"Star-type"high-speed railway network has a positive promotion on economic and social development indicators of Henan,such as social fixed assets investment,foreign capital utilization,per capita Gross Domestic Product(GDP),urbanization rate,employment upgrading index,etc.The amount of optimized comprehensive energy consumption and comprehensive operational emission reduction in railway passenger transport has steadily increased,and industrial SO2 emissions reduced,with significant ecological environment effects.
