Evolutionary Game Analysis on Defensive Competitive Intelligence between Peer Inter-Enterprises

In this paper, we use evolutionary game theory to build an evolutionary game model for peer inter-enterprise and analyze the evolutionary process and evolutionary stable strategy of implementing defensive competitive intelligence. It shows that when the costs of collecting and protecting invested by the peer inter-enterprises less than the costs of benefits competed by two sides, the long-run equilibrium results of peer inter-enterprises tends to be Tit-for-Tat stable strategies. And, which kind of stable Tit-for-Tat strategy to be chose decided by game payoff matrix and the initial system state influence of peer inter-enterprises. We also conclude that reduce the costs of protecting information in order to increase the benefits caused by implementing the strategy of protecting information appropriately can promote peer inter-enterprise defensive competitive intelligence.
