High‐Speed Rail Opening and Corporate Environmental Responsibility Performance: Analysis of Talent Aggregation and Supervisory Pressure

Abstract

The existing literature has explored the impact of high‐speed rail (HSR) opening on macrolevel environmental performance. However, few studies have validated its effects on microlevel corporate environmental responsibility performance. Therefore, on the basis of data from Chinese A‐share listed companies from 2011 to 2020, we examine the relationship between HSR opening and corporate environmental responsibility performance, along with the underlying reasons for this relationship. Our research reveals that HSR opening can significantly improve the corporate environmental responsibility performance. Talent aggregation and supervisory pressure constitute the two main channels that explain the positive relationship. Furthermore, the results of heterogeneity tests indicate that this positive effect is more significant in cities with larger populations and administrative centers, as well as in nonpolluting industries and companies certified through ISO14001 environmental management systems. This paper confirms that HSR opening contributes to generating positive externalities for firms and provides valuable insights into improving and understanding corporate environmental responsibility performance.
