Transportation infrastructure, competition and productivity: Theory and evidence from China

Chong Liu, Wei Wang and Qunfeng Wu

Economics Letters, 2019, vol. 174, issue C, 74-77

Abstract: This paper investigates the impacts of transportation infrastructure expansions on firm productivity and productivity gaps between the private and state sectors in China. Heterogeneous firms compete strategically a la Cournot in a multi-region model of internal trade. We show that lower transportation costs generate stronger selection and higher productivity by triggering fiercer competition. State-owned enterprises, however, are less affected, resulting in a higher productivity gap between private and state firms. Our theoretical results are consistent with empirical findings from China.
