Abstract

More and more confirmed in the study of complex networks, the huge social and economic network is a complex network, and therefore occupies an important socio-economic network of the value of the supply chain network is a complex network, to explore the value of the supply chain network and the complex nature of the network will become inevitable direction of research and trends. In complex networks, it was found that there is a certain rich node and rich club phenomenon, that is, a fraction of nodes with a large number of connections, and these nodes tend to be connected to each other, forming a \complex networks also showed some of the same with and heterotypic sex, that is similar to the \In this paper, the mathematical definition, proof and reasoning methods quantitative study of the general complex value network model, define a complex value network model, model analysis, calculus of complex value network model, and by Qingdao and Beijing 96 survey of companies, the application of factor analysis and structural equation modeling approach to empirical research of the weak complex value network connection strength, form a rich nodes with distribution and weak connection strength understanding of complex value network. Through research, the following conclusions are summarized as follows: Considering the competitive nature of the node local world on the basis of strictly limited to initial conditions, this paper presents a general complex value network modeling method, and discuss the general complex value several evolution of the form of the network, several particularity the general value of the network, the reasoning priority connection fails, the general complex value network does not have the small-world nature; simplified form of complex value network rich node and with with discussion, aware of the complex value network is the same with the network, but there is no rich man's club phenomenon. Through empirical analysis, we recognize the strong connection to play an important role in the complex value network, weakly connected manifested in the complex value network strength is not obvious, and for the strength of the connection of various factors, the following conclusions: (1) basically a positive correlation between complex value network to pay the costs and the stability of the enterprises; complex value network to pay the costs and transaction costs are not a negative correlation between. (2) trust, transfer costs and the stability of the enterprises is positively correlated; contractual relations and the stability of the enterprise is not a positive correlation between; trust and transaction costs is not a negative correlation between. (3) the stability of the supplier, based on the \Through further analysis, the article summarizes the generation of strongly connected with with and time factors rooted in a complex value network. , There is a high degree of aggregation in the same network with complex value - connected to the same with a high degree of aggregation phenomenon, can be considered to be a similar, having similar resistance nodes easily with each other to generate a strong connection, and with the time of the linear growth, but also deepen the degree of connection of such a high degree of aggregation - a high degree of aggregation. In practical applications, enterprises should focus on strengthening cooperation and structurally similar enterprise, the same with the complex value network, give full play to the role of strong connections to enhance their role in the complex value network.
