摘　　要：在网络效应明显的市场上 ,消费者预期、用户基数、网络规模等因素与正反馈效应的作用 ,使市场的均衡向一种具有网络优势的产品集中 ,最终会由这种产品主导市场。这一结果是由网络效应与进入壁垒的相互作用所产生的 ,网络效应抬高了市场的进入壁垒。把网络效应与进入壁垒联系起来可以更合理地分析软件市场上的反垄断问题。When a market has network effect, consumer's expectation, installed base, and feedback effect, the three factors having close relationships with network effect, will interact, which will make market equilibrium tip to one product with bigger scale of installed base, causeing competitive processes to have monopoly outcomes. Network effect is an important entry barrier, and enhances the other entry barriers. Microsoft has implemented network effect and entry barriers to get market monopoly position.
