Research On Knowledge-Sharing Among Supply Chain Enterprises Based On Complex Network Theory

With the development of economic globalization and knowledge economy, the competition has changed gradually from among enterprises to among supply chain. In the supply chain, different enterprise has different and complementary substance and knowledge. Therefore, knowledge-sharing is helpful to reduce the cost of the knowledge-sharing of each enterprise, enhance the knowledge utilization, create more excellent products, and enhance competitive edge of the whole supply chain.Based on the complex network, knowledge-sharing network model was established among the supply chain enterprises, discussed the knowledge-sharing rule, according to the establishment of the dynamic game model of perfect information, and went deep analysis to the condition and influence factors of knowledge-sharing among the supply chain enterprises. The main work included the following aspects:(1) Firstly, supply chain knowledge management, complex network as well as game theory were reviewed and summarized, put forward the content and the frame of the paper.(2) Based on three dimensions of complex network:structural dimension, relational dimension and cognitive dimension, analyzed the influence factors of knowledge-sharing network among the supply chain enterprises, built knowledge-sharing network model among the supply chain enterprises and used complex network to analysis it.(3) In the process of knowledge-sharing among the supply chain enterprises, each enterprise maximizes its profit under the process of knowledge-sharing in the knowledge-sharing network, and it will have an effect on the whole profit in the supply chain. Based on the Stackelberg model, this paper used game theory to analysis knowledge-sharing among the supply chain enterprises from the three aspects:①the strategy of non-knowledge-sharing between the manufacturer M and the supplier S;②the strategy of one-knowledge-sharing between the manufacturer M and the supplier S;③the strategy of repeated-knowledge-sharing between the manufacturer M and supplier S.(4) Measures and suggestions to promote the knowledge-sharing were studied among the supply chain enterprises.
