Cultural shock of high‐speed rail: Evidence from social trust

Abstract

AbstractThe opening of high‐speed rail (HSR), as an exogenous shock, has had a profound and complex effect on social life. This study analyzes the effect of the opening of HSR on social trust. Results show that the opening of HSR promotes social trust. Mechanism analysis showed that although the opening of HSR accelerated population mobility and decreased trust in strangers, economic growth and improvement of local social issues mitigated the negative effects of its opening. In addition, our results also show that individuals turn to trust in their parents, neighbors, and doctors. Considering the potential endogeneity problem, instrumental variable and difference‐in‐differences estimators consistently indicated the promoting effect of the HSR opening on trust. Heterogeneity analysis showed that the opening of HSR had a greater effect on female, urban residents, younger groups, and married people. Last, cities with larger populations and tourist cities were more vulnerable to shocks.
