Based on the customer dominated logic and enabling theory， it revealed the enabling mechanism of products in the sharing economy and verified its influence on product sales and price. The product enabling mechanism is the mechanism by which the sellers obtain information， resources and knowledge through the sharing network， and enhance the product value innovation ability. This mechanism is the result of the interaction between the seller's choice of transaction and the structure of residual rights. Based on the sellers’ behavior path of “acquiring residual ownership-enabling product-improving sales-price competitive”， it constructed the two-stage game model of product enabling. The empirical results show that： product enabling has a positive impact on sales and price； the effect of product enabling on sales is inhibited by price and reviews； when the enabling level passes the critical value （3 points）， it has a positive impact on sales； when the enabling level passes the critical value （4 points）， it has a positive impact on price. The results suggest that the sharing platform should adopt the arrangement of asymmetric property rights system，it is used to stimulate the innovation vitality of numerous sellers and reshape the unique competitive advantage of the platform.
