Research on the impact of high-speed railway opening on regional economy and environment - evidence based on Henan Province

摘要

The opening of high-speed rail has a great role in promoting regional economy. Many scholars have used prefecture-level cities across the country as samples to prove that the opening of high-speed rail can stimulate economic growth and reduce environmental pollution. However, the heterogeneity between regions may make the result no longer significant in a particular region. Therefore, this article uses the data of 17 prefecture-level cities in Henan Province as an example to explore the economic and environmental effects of the opening of high-speed rail in Henan Province, and study one of the mechanisms by which high-speed rail acts on the environment. The results prove that the opening of high-speed rail has a significant positive effect on the economic and environmental quality of cities in Henan Province. In addition, high-speed rail can also improve the environment by adjusting the industrial structure, reducing pollutant emissions, and improving environmental quality.
