摘　　要：通过对存在网络外部性下的两阶段 Hotelling 模型进行了研究和分析,研究了网络产品的价格竞争和差异化竞争,并对市场均衡存在的条件进行了分析.研究表明:网络产品差异化竞争遵循"最大差异化"原则,并且市场份额成为获胜的关键.最后,还对网络产品歧视价格与单一价格进行了比较研究,企业通过价格歧视可以缓解网络外部性对企业利润造成的压力,但不会导致社会福利水平的变化.Through studying and analyzing the two stages Hotelling model considering network externalities, the paper studies the price and differentiation competition between network goods, and analyzes the condition that market equilibrium exists. Research results indicates that differentiation competition between network goods obeys ＂maximized differentiation＂ principle, and market share becomes a key success factor of the competition. Finally, the paper makes a comparative research between the price discrimination and the single price tactics of network goods. By price discrimination tactics companies can reduce the pressure of the profits caused by network externalities, but it does not change the social welfar level.
