Evolutionary Game Analysis of Knowledge Sharing in Asymmetric Upstream and Downstream Enterprises of Supply Chain

As the core of the production means of enterprises, knowledge has become the strategic resource of the supply chain. Through the knowledge sharing among the enterprises in the supply chain, the efficiency of knowledge innovation and application can be improved. In this paper, based on the state-of-the-art literature, the evolutionary game model of asymmetric upstream and downstream enterprises in the supply chain is built; the dynamic evolutionary process and the influencing factors of the selection of knowledge sharing strategies are analyzed. Based on those analysis, the results show that selecting knowledge sharing strategy in the upstream and downstream enterprises are affected by the factors: the cost coefficient of knowledge sharing, the risk coefficient of knowledge sharing, the gap between the amount of knowledge sharing of enterprises, which have negative correlation to selecting knowledge sharing strategy in the upstream and downstream enterprises; the coefficient of gains in social relationships, the synergistic effect coefficient of knowledge sharing, the incentive and punishment factor of knowledge sharing, which have positive correlation to selecting knowledge sharing strategy. On the basis of these factors, the concrete measures to promote knowledge sharing are put forward. This research has a positive significance for remodeling and strengthening the supply chain core advantages in the era of knowledge economy.
