网络外部性下OTT服务商和通信运营商合作行为的演化博弈分析

摘要

本文建立了基于网络外部性条件下的OTT服务商与运营商合作行为的演化博弈模型，通过模型推理与数值模拟对合作成本的分担与收益分配机制、网络外部性对合作的影响程度等问题进行了研究，结果显示：双方合作的概率与合作情况下的用户规模、参与方的网络外部性系数呈正比，与合作成本、背叛合作情况下的用户规模呈反比；存在一个合作情况下最优的网络效用收益分配比例，使得OTT服务商与运营商合作的可能性最大化；合作成本的分担与双方合作情况下的网络效用收益的分配呈正相关关系。%telecommunications operators based on network externalities , and studies cooperative cost and income allocation mecha-nism, as well as the impact level of network externalities on cooperation by model reasoning and data simulation .Results show the probability of cooperation of both sides has a positive correlation with user scale and network externalities coeffi -cient, while has a negative correlation with total cost of cooperation and betrayal user scale ;there is an optimal network effect incomes proportion under cooperation between the OTT service providers and telecommunications operators to maxi -mize the probability of cooperation between them;share of cooperation cost is positively related to the cooperative network effect income distribution.
