Along with the process of integration with the global economy going ahead increasingly fast, the business of the world transportation trade has come to unprecedented progress.To accord with global economic trends, port corporations of China are facing a serious challenge. As the challenge pattern of the world has changed in a wave of annexation and reorganization of enterprises, the result is the survival of the fittest, and the competitive market will be further developed. Secondly, the pattern of the world service will change, which will bring about the fact that the pattern of the future corporations will be transformed from the traditional passive service of granting customers' impersonal demands to creative service of active leading customers to their subjective demands and providing the whole solution.For a long time, port corporations of China have had giant throughput and have greatly developed their transportation function, and the system of ports corporations has also get rid of the area of combination of legislature and administration. Port corporations cannot make decisions on their own and operate flexibly. It makes the business relating to ports, such as industry by ports, trade, transportation, port service and modern logistic, not have corresponding development, and the structure of port function unsuitable and much single. The development of relating business is not balanced, thus making industry chain too short and radiant ability limited. It also shows that port corporations' value chain hasn't exerted itself and achieved its maximal effect, the whole ship corporations' incremental chain bringing the same result to. We can solve these problems after having analyzing the performance of the whole value chain of port corporations and the factors influencing ports incremental effect. For this reason, it is essential at the moment to make a deep study on incremental effect of port corporations.This paper applies a few theories, such as management of value chain,management and control of cost, and customer satisfaction. From the view point of the value chain, we analyze the sector of port corporations under ship incremental chain and apply input-output analysis, based on the actual data from the shanghai container stock company, to incremental chain of port corporations. On this basis, we lodge relevant on the means and strategies of advancing incremental effect of port corporations.The study consider that the mostly factors which can effect incremental effect of ports are total cost control and customer satisfaction. In order to make the incremental effect maximize, we need wipe off "the no incremental task" and optimize "incremental task". We should make total cost decrease sostenuto, to optimize the task chain. On this basis, we can got customers' anticipate of value and form a customer value chain. When we optimize these two chains, then we can maximize the incremental effect. |
