Research Of Dynamic Measure And Driving Mode Of Relationship Between Harbor And City

With the concept of “world economic integration” has been put forward, the free flow of commodity capital and labor force between areas and countries also has been promoted, with the help of specific international division of labor and plenty of capital invested abroad international trade achieved a further development, moreover above all the contribution from harbor was top of them. Harbor city, by means of peculiar resource advantage such as advantageous geographical location, convenient transportation around the world and attraction to foreign capital, can lead to readjustment of industrial structure not only in some area but also worldwide rely on synergistic effect, agglomeration effect and self propagation. In the process of world economic development,harbor city as an indispensable force has been the door of external trade with the others and an important factor which closely related to the probability that one country join the wave of world economic integration successfully. So the harbor will be more important in taking part in international division of labor.Harbor city interaction, as the key factor of harbor city formation, evaluation and achieving sustainable development, has significant influence. Therefore, how to measure the relationship between harbor and city and to reveal the pattern of interaction between harbor and city is a difficult problem in the area of the study on the harbor city. For a long time, not only the study about the quantitative analysis method which was designed for analyzing the function of harbor and city is relatively weak, but also the research on connection mechanism of harbor city interaction can not succeed in obtaining a satisfactory conclusion. On the basis of quantitative measure methods, the conception, connotation and algorithm of DCI(Dynamic Concentration Index) were put forward, furthermore on which the status of interaction between harbor and city, on which the status of interaction between harbor and city of major cities in Circum-Bohai-Sea, from two angles which are dynamic development speed and developmental scale, has been measured quantitatively with the help of elasticity coefficient and Relatively concentrated index concerning harbor-city development.The results clearly showed that the status of interaction between harbor and city of 12 harbor cities in Circum-Bohai-Sea can be accurately divided into three types which are harbor driven pattern that composed of Rizhao, Cangzhou, Yingkou, Qinhuangdao, Dandong, Tangshan and Jinzhou, city driven pattern that composed of Qingdao, Dalian, Weihai and Tianjin and harbor-city balanced driven pattern that contained Yantai alone. What’s more, the changing tendency were quantitatively measured in three time periods(1997-2001, 2002-2006 and 2007-2011), it can be divided into continued rising, continued declining and fluctuating three types. Driving mode of harbor city was systematically analyzed by using impulse response function based on VAR(Vector Auto regression) model. Further mare, variance decomposition analyses of contribution to the development of harbor and city has been done, the degree of contribution can be divided into four types which are significant less significant weak and Insignificant.According to the DCI, relationship between harbor and city was analyzed based on impulse response theory. Afterwards, the mode of interaction of different relationship between harbor and city was divided as well as driving mechanism and driving factors. In the end, the specific differences and connections which closely linked with the interaction between harbor and city in different harbor cities were profoundly revealed. With the help of this study, the recognition of the internal mechanism of relationship between harbor and city on the geography side was efficiently enriched. At last based on the advanced experience of large harbor in domestic and overseas this paper puts forward some advices for the development of the harbor cities around Circum-Bohai-Sea in order to make some contribution to relevant research field.
