Analysis Of The Promotion Of Trade Profit Based On Port Industry Chain Efficiency

The development of port industry is an important support to open economy, besides, port industry plays a great role on both internal and external outspread and aggregation. Through the analysis of the effect of port industry chain efficiency on trade profit, we can know more of the interaction relation between port industry and open economy, and then more trade profit can be obtained.This article analyzed the promotion of trade profit based on the port industry chain efficiency, both qualitatively and quantitatively.First, we analyzed port industry chain efficiency, and divided it into three levels: port technical efficiency, port structural efficiency, and port regional efficiency; two aspects:organization efficiency and operation efficiency. Second, we studied the mechanism of the promotion of trade profit based on the port industry chain efficiency. Through the promotion of port industry chain efficiency, both cargo transportation time and cost can be reduced. Thereby port trade facilitation is enhanced and more trade profit is made on the effect of the export incentiveness, import barriers cutting and aggregation-diffusion.Then, this paper constructed an index system from two aspects to estimate the port industry chain efficiency of six countries (regions). Fatherly, we applied the estimation result into the gravity model to do regression analysis. In this way, we provided a validation of the role of the port industry chain efficiency on the trade profit promotion.Finally, we put forward some measures to promote chinese port industry chain efficiency, based on the current circumstance.That is promoting industry chain technological efficiency by horizontal integration, promoting industry chain regional efficiency by community injustment, promoting industry chain structural efficiency by extending longitudinally.
