Abstract: In order to cope with the increasingly fierce market competition and obtain higher profits, online platform retailers choose to enter the retail market to sell the products independently. This article focuses on the channel structure where online platform retailers are in a leading position, and analyzes the impact of online platform retailers' independent sales on channel members' profits and pricing strategies under transaction-based per-unit fee. The results show that independent sales of online platform retailers have brought positive spillover effects. When the competition coefficient is large enough, (1)the profits of channel members will be improved, and with the increase of market competition, the profits of channel members will increase more significantly; (2)online platform retailers are likely to announce higher platform fee, and possibly channel members also set higher retail price. More importantly, under the independent sales model of online platform retailers, the overall profit of the channel has been improved, and there is a Pareto improvement.
