在2个服务商竞争基础上分析附加增值服务对服务商定价以及外包需求的影响,给出服务商跟随策略选择的判据;运用演化博弈论分析服务商横向决策的动态演化过程。研究表明,提供服务的投入产出比在合适的范围才会达到降低对手需求和迫使对方降价的良好效果,且服务商跟随策略的选择与投入产出比值是相关联的;此外,系统演化的均衡结果以及横向服务联盟的缔结进程快慢会受到合作初始意愿、违约惩罚成本以及专用性投资费用的影响。
Based on the competition of two service providers, this paper analyzes the influence of additional value-added service on the pricing and outsourcing demand of service providers, and gives the criterion of service providers’ follow-up strategy selection. Using evolutionary game theory, the dynamic evolution of service provider’s horizontal decision-making is analyzed. The research shows that the input-output ratio of service delivery is good enough to lower the demand of opponents and lower the price of each other, and the ratio of service providers’ follow-up strategy to input-output ratio is more than that of system evolution. In addition, The outcome of the equilibrium and the conclusion of the horizontal service alliance will be affected by the initial willingness to cooperate, the cost of default penalties and the cost of earmarked investment.
