The Research Of Bonded Port Area Enterprise Cluster Evolution Based On Cluster Supply Chain

As a fenced-in industrial estate supervised by customs in port area or in the wider port hinterland, boned port area has more competitive advantages compared to other counterparts in China. Chinese boned port area have undertaken the dual roles of'windows'in developing the foreign-oriented economy and of'radiators'in accelerating inland economic development by introducing a series of reforms in the foreign free trade zone system by running these areas with a off shore location, more flexible business regulation, multi-functions and different preferential policies. Thus, it has become an indispensable part of global supply chain and international trade and targeted by increasing domestic and international enterprises from logistics, manufacturing, warehousing, trading, finance and information industries. With the complexion and diversity of boned port area enterprise cluster, it is no longer a simple sense of "enterprises get together", but the expansion and integration of different commodity chains. What type of organizational mode could ensure the effectiveness and efficiency of bonded port area cluster? And based on this type of organizational mode, how does boned port area enterprise group evolve?From the perspective of cluster supply chain, this paper studies the evolution of boned port area enterprise group in a systematically mythologies. Firstly, through the analysis of the characteristics, current situations and future trends of boned port area, it is notified that boned port area could be taken as a complex system with multi-factors. Thus, similar to biological evolution, boned port area has the periodical evolution process, which could be divided into five phases that consist of aggregation, specialized division, integration of vertical supply chain and horizontal function chain, innovational development and recession or transformation. It is noting that there exist external influence factors featured by infrastructure environment, policies and market demand, also influenced by internal cluster supply chain network.On the basis of qualitative study, combining cellular automation with logistics function to build simulation model suitable for boned port area with characteristics of cluster supply chain and complex system. In this model, each enterprise in boned port area is taken as a cellular, and its state in the next time is not only decided by the states of itself and neighbor cells in the former time, but only influenced by external and internal factors mentioned before. Then. Matlab 7.1 software is applied to carry out simulation. Finally, cellular distribution map of core-enterprises and middle-small enterprises and variations curves of number of total enterprises, enterprises in growth state, entering state and declining state with time are obtained. Furthermore, other four simulation results are gotten by altering initial values of varies factor functions. Followed by comparative analysis, it is concluded that cluster supply chain network influences boned port area enterprise group most, infrastructure environment takes the second place, then policy and market demand after it. In the final section, Chongqing CunTan boned port area is taken as an example, some suguestions about how to accerelate boned port area enterprise cluster development are proposed.In a nutshell, cluster supply chain plays an important role in boned port area enterprise cluster. It is an advanced and efficiency organizational model when the development of boned port area approaches to a certain stage. This paper has far-reaching significance for the optimization of boned port area management and planning system.
