We examine the motivations for an online retailer that exclusively resells goods to open its platform to competing sellers. We further examine competing seller’s incentives to join such a platform. The retailer can receive rent and commission from the competing sellers or third-party (3P) sellers who join the platform. Further, these 3P sellers can increase their customer reach through the retailer’s platform. However, the competition between them may intensify as both parties sell identical products on the same platform. This study develops a game-theoretic model to formulate the strategic interaction between an online retailer and a 3P seller who are selling an identical product in the market. According to our findings, opening the platform changes the rules of the game. By charging rent and commission, the retailer can reduce their price competition with the 3P seller. In particular, the retailer has more control over the 3P seller’s retail price through charging commission. Hence, both parties benefit from coopetition if consumers are insensitive to price changes. Certainly, if consumers are sensitive to price changes, it may not be in the retailer’s interests to open up the platform. Additionally, platform sharing provides consumers with an additional channel from which to purchase products. However, consumers are at a disadvantage as they have to pay a higher price than they did before the execution of the platform opening strategy. In conclusion, the retailer’s choice to open up its platform decreases social welfare (SW).

平台共享:从经销商到市场

我们研究了一家专门转售商品的在线零售商向竞争卖家开放其平台的动机。我们进一步研究了竞争卖家加入这样一个平台的动机。零售商可以从竞争卖家或加入平台的第三方(3P)卖家那里收取租金和佣金。此外,这些 3P 卖家可以通过零售商的平台扩大他们的客户范围。然而,随着双方在同一平台上销售相同的产品,他们之间的竞争可能会加剧。本研究开发了一个博弈论模型来制定在线零售商和在市场上销售相同产品的 3P 卖家之间的战略互动。根据我们的发现,开放平台会改变游戏规则。通过收取租金和佣金,零售商可以减少与 3P 卖家的价格竞争。尤其是零售商通过收取佣金对3P卖家的零售价格有更多的控制权。因此,如果消费者对价格变化不敏感,双方都将从竞争中受益。当然,如果消费者对价格变化敏感,那么开放平台可能不符合零售商的利益。此外,平台共享为消费者提供了购买产品的额外渠道。然而,消费者处于劣势,因为他们必须付出比执行平台开放战略之前更高的价格。总之,零售商选择开放其平台会降低社会福利(SW)。零售商通过收取佣金对3P卖家的零售价格有更多的控制权。因此,如果消费者对价格变化不敏感,双方都将从竞争中受益。当然,如果消费者对价格变化敏感,那么开放平台可能不符合零售商的利益。此外,平台共享为消费者提供了购买产品的额外渠道。然而,消费者处于劣势,因为他们必须付出比执行平台开放战略之前更高的价格。总之,零售商选择开放其平台会降低社会福利(SW)。零售商通过收取佣金对3P卖家的零售价格有更多的控制权。因此,如果消费者对价格变化不敏感,双方都将从竞争中受益。当然,如果消费者对价格变化敏感,那么开放平台可能不符合零售商的利益。此外,平台共享为消费者提供了购买产品的额外渠道。然而,消费者处于劣势,因为他们必须付出比执行平台开放战略之前更高的价格。总之,零售商选择开放其平台会降低社会福利(SW)。开放平台可能不符合零售商的利益。此外,平台共享为消费者提供了购买产品的额外渠道。然而,消费者处于劣势,因为他们必须付出比执行平台开放战略之前更高的价格。总之,零售商选择开放其平台会降低社会福利(SW)。开放平台可能不符合零售商的利益。此外,平台共享为消费者提供了购买产品的额外渠道。然而,消费者处于劣势,因为他们必须付出比执行平台开放战略之前更高的价格。总之,零售商选择开放其平台会降低社会福利(SW)。
