有限开放竞争中企业战略合作动因的短期分析

为显示企业进行战略合作的动因，在短期假设和有限开放竞争市场条件下，应用军备竞赛模型和与之对应的军事同盟模型对企业单纯竞争与战略合作两种战略行为的结果进行了对比分析。分析说明，当两企业进行战略合作时，其在稳态下的市场份额均高于其在单纯竞争时稳态下的市场份额，即战略合作不仅可以使原来作为竞争对手的两企业实现“共生”，而又还可以“共荣”，从而证明合作可以带来正面的效益。所以，企业进行战略合作的动因来源于合作的效益。

A Short-term Analysis of the Motive of Strategic Cooperation of Firms under the Condition of Limited Open Competition

To expose the motive of strategic cooperation of firms, a comparative analysis, of the different outcomes of the strategy of purely competition and the strategy of cooperation, had been done by the application of the Arms Race model and Insecurity Alliances model under the conditions of short-term hypothesis and limited open competition. The analysis reveals , that is the market share of the stable state when the firm joining in the cooperation is more than the one of the stable state when the firm selects purely competitive strategy, i.e., the strategic cooperation not only make the two firms, who are competitive matches, go to symbiosis, but also common stronger, and it is proved that the positive benefit come from cooperation exists. So the motive of strategic cooperation of firms comes from the cooperative benefit.
