The Research About Identifying Influencing Factors Of Industry Clusters’ Scale Effect

Since the industrial cluster was born,it has become research focus of scholars at home and abroad.But it is regrettable that there is little systematic research about industrial clusters’ scale.In practice,industrial cluster in our country doesn’t keep a reasonable size so that seriously hamper its upgrading and sustainable development.Therefore,the study of industrial cluster scale of important theoretical and practical significance.Industrial clusters generally have obvious scale effect.But it doesn’t mean that the size of the cluster is the bigger the better.This paper emphasize that the clusters should keep a reasonable scale.If the cluster size is too small,it can not give full play to the economies of scale;if the size is too large,a series of negative phenomena such as vicious competition,excessive consumption of resources,serious environmental damage in industrial cluster may happen,so scale economies will be limited.All problems above raises our deep thoughts about the evolution process of industrial clusters: first,what factors will affect the industrial cluster’s scale effect? Second,how is the maximum scale of cluster(this paper choose total assets to measure it)influenced by above factors.This paper makes use of literature induction to identify typical influencing factors including elements such as endowment,industry capacity,community resources,government policies,the ability of market radiation,external investment,enterprise financial situation,business types of industrial clusters,risk appetite of companies.Subsequently,applying cellular automaton that a effective tools for complex systems to study the problem of industrial cluster scale,this paper adopt the bottom-up research way and build cellular automaton model of industrial cluster’s scale development combined with actual situation.Through computer simulation experiment,two issues have been discussed that critical influencing factors of cluster best size and cluster economies of scale.In response to these studies,this paper finally reaches the following conclusions:descending order of the impact of various factors on the cluster size are:business risk appetite,market capacity,financial condition,the ability of market radiation,factor endowments,external investment,social resources and government policies.And,there are some targeted advice to help industrial clusters gain scale effect from following six aspects: the establishment of benefit-sharing mechanism,strengthening competition and cooperation,improving the cluster intermediary servicesystem,the development of brand strategy and building a service-oriented government.
