Abstract
This paper suggests an extending conventional gravity model design to empirically analyze the effect of transport costs and port efficiency on China’s export flows. It shows that factor endowment and transport costs variables affect export trade value in directions that New Trade Theory (NTT) predicted. Also, the evidence indicates that, controlling for the effects of transport costs on trade, variables in traditional gravity model are consistent with previous empirical studies in both magnitudes and directions. Moreover, more than 22% of the variation in Chinese export trade can be explained by those three variables alone. The findings reported in this paper empirically explains how seriously transport costs and port efficiency affect China’s export growth by comparing effects of labour production factor costs on external trade. It suggests that the improvement of port efficiency and reduction of road transport costs play a vital role in China’s export competitiveness in the global market.
