Abstract: The improvement of resource allocation efficiency of manufacturing enterprises is an important source of economic growth efficiencyThis paper takes resource allocation as the starting point，constructs the enterprise traffic road index，and examines the impact of improved traffic accessibility on the microeconomic performance of enterprisesThe research finds that the improvement of accessibility can improve the efficiency of enterprise resource allocation by reducing enterprise inventory，reducing price markup and strengthening innovation incentives；the improvement of transportation plays a greater role in improving the resource mismatch of labor and resource intensive enterprises and export enterprises than that of capital and technology intensive enterprises and domestic enterprises；traffic construction can optimize the resource allocation efficiency of eastern enterprises and nonstateowned enterprises，but it will aggravate the resource mismatch among enterprises in central，western，northeastern enterprises and stateowned enterprises
