Research on dynamic measurement and driving mode of harbour-city relationship in the Bohai Rim in China

Abstract

Harbour-city interaction plays a major part in the formation, evaluation and sustainable development of a harbour city. Therefore, how to measure the relationship between harbour and city and to reveal the pattern of interaction between harbour and city is a difficult problem in the area of the study on the harbour city. For a long time, not only the study about the quantitative analysis method which was designed for analyzing the function of harbour and city is relatively weak, but also the research on connection mechanism of harbour city interaction can not obtain a satisfactory conclusion. On the basis of RCI(Relative Concentration Index), the conception, connotation and algorithm of DCI(Dynamic Concentration Index) were put forward, furthermore the interaction between harbour and city and changing tendency mainly in three periods of 1997-2001, 2002-2006 and 2007-2011 for the major harbor cities in the Bohai Rim were quantitatively measured. The main port cities in this region consisted of Rizhao, Cangzhou, Yingkou, Qinhuangdao, Dandong, Tangshan, Jinzhou, Yantai, Qingdao, Dalian, Weihai and Tianjin. At last the driving mode of harbour city was systematically analysed by using impulse response function based on VAR(Vector Auto regression) model. The results clearly showed that the status of interaction between harbour and city of 12 harbor cities in the Bohai Rim can be accurately divided into three types: harbor driven pattern(Rizhao, Cangzhou, Yingkou, Qinhuangdao, Dandong, Tangshan and Jinzhou); city driven pattern(Qingdao,Dalian, Weihai and Tianjin four harbour cities) and harbor-city balance driven pattern(Yantai).What's more, the changing tendency can be devided into three types(continual rise, continual decline and fluctuation). According to the DCI, the relationship between harbour and city was analysed based on impulse response theory. Afterwards, the mode of interaction of different relationships between harbor and city were divided as well as that of driving mechanism and driving factors. In the end, the specific differences and connections which were closely linked with the interaction between harbour and city in different harbour cities were profoundly revealed.With the help of this study, the recognition of the internal mechanism of relationship between harbour and city in the geographical perspective was efficiently enriched.
