摘要
为了对电信增值业务供应链进行进一步的研究,本文对服务提供商收入有信息费分成和广告收入两个组成的单个电信运营商多个服务提供商的单主多从Stackelberg模型进行建模和实证仿真分析,并与服务提供商只有信息费分成一种收入来源时做了对比。仿真结果表明,供应链存在双边际效应、主导企业最大程度榨取供应链上利润的资本本质,及企业利用信息不对称等可以提升自己的利润空间。最后,本文讨论了Stackelberg模型存在的缺陷,即存在均衡解与最优解之间的平衡问题等,并提出了一些有意义的结论和建议,可供电信供应链上的企业参考。
In order to research the telecom value-added supply chain deeply, constructed the multi-followers Stackelberg game model with multi service providers whose incomes composed of information fee division and adverstisements, then simulated with a demonstration, and compared with the situation of service providers＇ income corned from information fee division only. The simulated and compared results show that, supply chain has double marginalization effects, the enterprises in the supply chain have the nature of pursing the maximum profits in the capital markets, and some enterprise can get more profits with the information asymmetry, at last discussed the fault of the Stackelberg model existed, which is that the balance problem between equilibrium and optimal solution, and proposed some significant suggestions which can be referenced bv the enterorises in the telecom supply chain.
