本文将系统的数理建模方法引入竞争战略领域,并首次与财务分析结合进行竞争战略识别博弈建模.开发基于不对称效用函数并含有DuPont体系财务参数的Nash均衡模型,提出等绩效约束条件,以Porter的差异化战略定义和溢价条件为前提,发现通过Nash均衡解和该约束条件导出从业战略的基本性质的路径,应用于检验Palepu识别假设.初次从数理模型导出几个从业战略的性质定理和Porter-DuPont-Nash战略识别准则.理论推演显示:成本领先战略是内生的;纯成本领先战略的基本特性是具有对纯差异化战略的成本优势,生产率优势和价格优势;纯差异化战略具有单位产品利润优势;而混合战略则具有除价格以外的全部优势.通过数理推演首次给出了Palepu假设与Porter溢价条件不一致的证明.
In this paper, the mathematical modeling method of the system is introduced into the field of competitive strategy, and for the first time combined with financial analysis for competitive strategy identification game modeling.Nash equilibrium model based on the asymmetric utility function and containing DuPont financial parameters is developed, and other performance constraints are proposed, Based on Porter’s definition of differentiated strategy and premium conditions, we find that the basic nature of the strategy is derived from Nash equilibrium and the constraint, which is used to test Palepu’s recognition hypothesis. The qualitative theorems of several strategies And Porter-DuPont-Nash strategy identification theory.The theoretical deduction shows that the cost-leading strategy is endogenous; the basic characteristics of the pure cost leadership strategy are the cost advantage, productivity advantage and price advantage of pure differentiation strategy; pure differentiation strategy Has the advantage of unit profit, while the hybrid strategy has all the advantages except the price.For the first time, the mathematical deduction proves that the Palepu assumption is inconsistent with the Porter premium condition.
