ABSTRACT
This paper takes the listed companies registered in prefecture-level cities from 2008 to 2014 as samples and uses the difference in difference method (DID) to explore the relationship between the opening of high-speed railways and enterprise performance level. The research finds that the opening of high-speed railways promotes the improvement of enterprise performance levels. The group test found that for companies with higher financing degrees, the opening of high-speed railways has a more significant effect on improving corporate performance. This paper enriches the research on the microeconomic consequences of high-speed railway opening and provides valuable suggestions for improving the enterprise management system.
