摘要:基于消费者效用理论,分别讨论了市场中存在垄断和双寡头内容提供商在网络非中立时与服务提供商的合作策略,研究了不同策略选择对内容提供商广告投放数量和利润的影响,得出满足两者合作均衡策略的条件。研究表明:市场中存在双寡头内容提供商情形下,内容提供商与服务提供商的合作会扩大市场总需求,且随着合作的内容提供商数量增多,市场总需求也随之增大。服务水平增加值和单位服务成本会对内容提供商的合作策略选择产生影响。服务水平增加值较小时,内容提供商都选择不与服务提供商合作;当服务水平增加值较大时,内容提供商不会同时选择与服务提供商合作,而是其中一个内容提供商选择合作另一个就不合作。

The more content providers cooperate, the larger market demand is. In addition, the increased level of service value makes a good difference to cooperation strategy. When increased level is low, the content providers will not collaborate with the service provider. When increased level is high, the two content provider will not collaborate with the service provider together rather than only one content provider will cooperate.

引言
随着互联网的迅速发展和竞争的日益激烈,服务提供商受到来自内容提供商产品的影响,如微信、Skype等应用程序,现有的经营模式受到了挑战。为了摆脱这一困境,服务提供商对内容提供商采取歧视策略,对其采取差异化的服务支持,内容提供商面对这种情况选择正确的合作策略对自身利益显得格外重要。然而,网络中立性原则对企业的决策却产生着影响,Wu提出网络中立性的概念,指出互联网上的服务提供商应当平等对待所有服务和访问,尤其是数据传输的优先级,应当防止从商业角度出发对其进行控制[1]。……
