To address this concern, we provide econometric evidence on the productivity of road investment in China using panel data of medium and large manufacturers nationwide during 1998-2007. We extend the model of Fernald (1999) to allow for imperfect competition. To address endogeneity in road investment, we estimate the differential impact of road investment on the productivity growth of firms with different transport reliance. Our estimates suggest a rate of return of approximately 83%, which is large enough to reject the excessiveness of road infrastructure in China during the sample period. Moreover, contrary to common criticism, we find that the productivity of roads is higher in inland China, where institutional quality is lower. 歡迎廣大師生參加！
