双寡头产品质量定位与后发优势

Strategic Choices of Product Quality and Second-Mover Advantages in Duopoly

按照成熟技术和不成熟技术两种情况,讨论了两个潜在的企业进入者最优的产品质量选择,结果表明:在技术成熟时,先行企业会选择高质量的产品并获得先行优势;在技术不成熟的动态竞争中,如果产品质量改进的成本是递增的,就不会存在先行优势,要么出现利润均等,要么出现后动企业的后发优势.

This paper explored two potential entrants' product quality choices when feasible technology is mature or not, and drew conclusions that under every semi-convex fixed-cost function of quality the first mover will certainly choose higher quality and earn higher profit under the first circumstance, otherwise there is a rent equalization equilibrium or second-mover advantages will occur.
