Study On Shipping Service Elements Agglomeration Based On Symbiosis Theory

With the development of the globalization of international trade,the development of shipping industry tends to the agglomeration situation.The international shipping center is no longer confined to the concept of port or hub,but to be the agglomeration symbiotic platform of all kinds of shipping elements relying on city.How to make good use of this platform to highlight the scale effect of shipping service elements glomeration and enhance the competitiveness of international shipping center is still a current research hot spot.The knowledge of Shipping services,agglomeration theory and symbiosis theory have been systematically summarized.The relationship of shipping services and international shipping center is straightened out.The theoretical basis of the thesis is based on above all of these.The symbiosis system of shipping service elements agglomeration is established.The connotation,conditions and symbiosis characteristics of shipping service elements agglomeration have been respectively discussed.The three symbiosis elements,symbiosis index and symbiotic mechanism of shipping service elements agglomeration have been systematically analyzed.The symbiosis model and symbiosis effect of the agglomeration development of shipping service elements have been theoretically analyzed.Taking Xiamen international shipping center as the research object,the agglomeration conditions and agglomeration status of shipping service elements have been studied.The symbiosis unit and main quality parameters are selected.The symbiosis degree and symbiosis coefficient have been calculated.The Lotka-Volterra model is established for the shipping service elements agglomeration symbiosis system of Xiamen international shipping center.The results show,the symbiosis energy of the symbiosis system has been produced.From the way of behavior,the symbiosis relationship is an asymmetric mutualism model.From the way of organization,the symbiosis relationship is an intermittent symbiosis model and continuous symbiosis model.Finally,according to the problems existing in the shipping service elements agglomeration symbiosis system of Xiamen international shipping center,some suggestions about symbiosis environment,symbiosis unit and symbiosis idea have been put forward,which has certain reference significance to enhance the comprehensive competitiveness of Xiamen international shipping center.
