Research On Modeling Product Network And Characteristics For Enterprise Cluster

Enterprise Clusters play an important role in enhancing the competitiveness and promote economic growth of local industry, and its development needs the supporting on scientific and rational policy, so the operation mode of enterprise clusters was researched from microcosmic level. Enterprise cluster is a complex system of network, the system has its own complexity that makes it possible use the complex network theory, the rich and scientific theoretical of complex network for the systematic analysis of enterprise cluster theory to provide effective support.The research has carried out by the method in which combined theoretical knowledge and practical data together. Based on the core of product and employing the methodologies of complex network, current study proposed enterprise cluster product network models. Based on the features and functions of the network were revealed and products structural characteristics were researched, the distribution of products and relationship between enterprises were researched. The main contents of this paper are as follows:First, the current situation of the research about enterprise cluster and methodologies of complex network were expatiated, and the significance and main contents of this paper were given. Considering the complexity of enterprise cluster system, methods were expounded on modeling different enterprise cluster networks. Based on the core of product and from the angle of client demands, a method of building enterprise cluster product network was proposed and the structure characteristics of product network were analyzed. The result was that the injection molding machine network of Ningbo has small world features, clustering properties and scale-free properties.Second, applying the community structure algorithm, the cluster products network was divided into many different communities, the result was that the community structure of injection products network of Ningbo was clear, and based on the communities which were divided the product series were classified. The products structure of enterprise clusters was analyzed with nodes degree, and the roles of products in the network were evaluated by the nodes Z - P matrix which was proposed by the use of nodes were connected in its community and other community, the product structure of the enterprise was researched and measures in order to promote product structure of rationalization cluster were put forward. Finally, cluster characteristics of enterprises were researched. The calculation method of enterprise center degree which was proposed was studied the roles of enterprises in the cluster. A method of enterprise product distribution coefficient calculation was proposed was used to analyze the corporate products in the distribution characteristics of the series. The study was found that most of the products of the enterprise cluster were in discrete distribution and some medium-sized enterprises were centralized production a series of products. Enterprise product correlation method to calculate the product correlation between enterprises was analyzed, and the cooperation and competitive characteristics between cluster enterprises were analyzed.
