| 摘 要： | 在产品不完全覆盖市场中,研究具有不对称网络外部性的纵向差异化产品的Bertrand价格竞争或Cournot数量竞争策略.研究表明,两产品在Cournot数量竞争中的市场利润和社会福利都大于在Bertrand价格竞争中的市场利润和社会福利.在Bertrand价格竞争或Cournot数量竞争中,当低质量产品的网络外部性较大且满足一定条件时,低质量产品也可以获得较大的市场利润;当高质量产品具有较大网络外部性,或网络外部性虽然较小但满足一定条件条件,网络外部性相等或产品都不具有网络外部性时,高质量产品获得较大的市场利润.随着网络外部性的增强,Cournot-Nash均衡点并不稳定,在重复博弈以后,均衡点向Bertrand-Nash均衡点靠近.

| Abstract: | Under incomplete coverage market,competitive strategies of Cournot or Bertrand of product with vertical differentiation and network externality are researched.According to the result,market profit and social welfare of product in Cournot competition are greater than those in Bertrand competition.In Bertrand competition or Cournot competition,when network externality low quality product is greater than that of high quality product and satisfies certain condition,low quality product obtains greater market pro... |
