服务供应商承诺的服务质量和实际的服务质量之间的差异会显著地影响其需求．从服务质量的可靠性维度和价格两个方面来分析服务供应商之间的竞争行为．服务需求由服务质量和价格共同决定．根据服务供应商的不同竞争行为，分别建立以下三种竞争模型：1．服务质量一定的情况下基于价格的竞争模型．服务供应商之间存在唯一的纳什均衡解；2．价格一定的情况下基于服务质量的竞争模型．服务供应商的最优决策不受其他任一服务供应商的影响；3．基于服务质量和价格同时竞争的模型．以服务供应商收益最大化为目标，得到每种竞争模型下服务供应商的最优价格、服务质量和相应的需求．服务供应商不同的竞争策略会产生不同的均衡行为．

The difference between service suppliers＇ promised service quality and actual service quality markedly influences their demand. Service suppliers compete with each other based on service quality and price, and service quality is expressed by service reliability. Service demand depends on all of the service suppliers＇ service quality and price in the market. The competition among service suppliers includes three types： 1. Price competition among service suppliers with given service level. There is a unique Nash equilibrium among service suppliers; 2. service quality competition among service suppliers with a fixed price. Every service supplier＇s optimal decision is not affected by other service suppliers; 3. service quality and price competition among service suppliers. With the objective of maximizing profit, service suppliers make the optimal choice of price, service quality and the corresponding service demand. It shows that service suppliers＇ different strategies result in different equilibrium behaviors.
