Abstract: Network structure and network information can have a direct influence on network function. To establish a mathematical model, with the corresponding mathematical analysis and stimulation validation uncovers the law about how the benefits of network subjects are affected. Two classes of network subjects are introduced and their benefits are defined, and accordingly, two cases of results are obtained according to the different situations of network information. The above results can deduce three conclusions and give management suggestions. Besides, the further research work is also discussed.

摘要： 网络结构和网络上的信息披露机制对网络功能的发挥有着直接的影响,建立相应的数学模型并采用数学分析和仿真验证的手段揭示其对于网络参与主体收益的影响规律,具有理论和应用价值。在明确网络中两类参与主体的基础上,定义了他们的收益,并根据信息披露的不同情形,分为两种情况求解模型,应用数学证明和仿真分析的手段得到了网络结构对收益影响规律的三个结论。在对结论分析的基础上,指出了模型的管理学意义,讨论了进一步的研究工作。
