报告摘要：

We study the platforms' choice when they compete for merchants and consumers by adopting unit fee or proportional fee. We find that: if the merchant is monopoly, adopting unit fee is platforms' weakly dominant strategy; however, if there are multiple merchants compete in Cournot, they have individual but not collective incentive to join platform adopting proportional fee, which leads to proportional fee equilibrium; if the merchants compete in Bertrand, the merchant has both individual and collective incentive to join platform adopting unit fee, which results in unit fee equilibrium. Our findings shed light on platform entry and vertical integration/separation.
