摘　　要：二手商品的大量产生带动了C2C逆向物流平台的兴起,而C2C逆向物流平台中的商品交易难度和商品的残余价值却很少被研究。将商品交易难度和商品的残余价值的乘积定义为商品效用,并且在Armstrong双边市场模型的基础上,引入商品效用这一因素,分别探索建立了寡头垄断市场中C2C逆向物流平台和双寡头竞争市场中C2C逆向物流平台的定价模型。研究发现:寡头垄断市场时,平台增加商品效用并不一定会增加利润。当处于双寡头竞争市场时存在两种情况:一是平台商品效用无差异时平台获得的利润与组间网络外部性系数有关;二是两平台商品效用有差异而卖家和买家获得的商品效用无差异时,平台获得的利润随两平台商品效用差在一定范围内单调递增。The booming of second-hand goods has driven the rise of the C2C reverse logistics platforms.However,the trading difficulty of commodities and the residual value of goods in the C2C reverse logistics platform are rarely studied.In this paper,the commodity utility,the multiplying of the difficulty of commodity trading with the residual value of goods,is introduced.Based on the Amstrong’s bilateral market model,the pricing model of C2C reverse logistics platform in two kinds of markets are studied,i.e.the monopoly market and the duopoly competition market.The research shows that in a monopoly market the platforms increase in commodity utility does not necessarily increase the platforms profit.When the platform is in a duopoly market,there are two situations.First,when the utility of the two platforms has no difference in utility,the profit obtained by the platform is related to the externality coefficient of the network between the two groups.Second,when there is difference in the utility of the two platforms while there is no difference in commodity utility of the platforms and there is no difference in goods obtained by the seller and the buyer,the profit obtained by the platform increases monotonouslyin a certain range with the utility difference between the two platforms.
