Title: Transportation Network and Market Integration: Evidence from China

Abstract: This paper examines the impact of China's expressway expansion between 1998 and 2007 on market integration and firm performance within the manufacturing sector. The rapid expansion of the transportation network significantly enhanced market connectivity, improving firms' access to both input and output markets and intensifying competition. We explore how individual firms are influenced by these changes in terms of productivity, intermediate input prices, and market power by developing a new approach to estimate these measures at the firm level. Our findings reveal that the expansion of the transportation network significantly improved firm centrality, leading to enhanced market access and increased competition. Improved upstream market access reduced input prices and raised markups, while better downstream access boosted productivity. Although increased competition exerted countervailing pressures, the effects of market access dominated. In addition, lower-performing firms, particularly those with lower productivity, higher input prices, and lower markups, benefited more from the network improvement, and consequently leads to regional convergence.
