本研究的目的是证明多产品双寡头垄断中的产品扩散策略是先动优势。我们考虑同时和Stackelberg品种的比赛。生产更多品种的企业要价更高，生产更大的总量，并获得更高的总收入。当企业依次选择大量的品种，然后同时决定价格时，领导者生产更多的品种，并享有先发优势。大量的品种可以被视为战略替代品，就像数量一样。最后，相对于社会最优值，市场可能提供太少的品种。
This study aims to show that the product proliferation strategy in multi‐product duopoly is first‐mover advantage. We consider simultaneous and Stackelberg variety competitions. A firm producing more varieties charges a higher price, produces larger total quantities, and earns higher total revenue. When firms sequentially choose the masses of varieties and then simultaneously decide prices, the leader produces more varieties and enjoys first‐mover advantage. The masses of varieties can be regarded as strategic substitutes in the same way that quantities are. Finally, the market is likely to provide too few varieties relative to the social optimum.
