Transportation Infrastructure and Productivity of Manufacturing Firms——Evidence from County-level Expressway Data and Chinese Industrial Enterprises Database / Long Xiaoning, Gao Xiang. // Journal of Huazhong Normal University（Humanities and Social Sciences) 2014, Vol 53, N.5

p43-p52

Existing literature is relative lack of research on transportation infrastructure from micro perspective. Using county-level expressway data and Chinese industrial enterprises database, this paper explores whether expressway can enhance productivity of manufacturing firms or not. According to our empirical analysis, expressway can reduce the time of cargo transport and decrease the time cost of travel,and then can promote the linkages of firms with external markets and service sectors in big cities. The conclusion of the empirical analysis argues that, generally, the average effect of expressway on the productivity of manufacturing firms is small; however, expressway can significantly improve the total factor productivity of manufacturing firms in small cities and firms which are far from big cities. Expressway can make important contribution in regional economic integration and reducing the imbalance among regions. So we should narrow the gap of transportation infrastructure among areas so as to improve regional development
