考虑网约车平台向出租车司机支付与私家车司机相同费率的方式，或对出租车订单收取抽成的方式开放平台，探讨平台的开放策略选择问题。分析不开放、网约车订单开放、出租车订单开放和混合开放4种策略，运用运筹优化的方法，构建平台利润模型，通过最大化平台利润得到4种情况下的最优决策。研究表明：4种策略都存在最优区间，市场中的潜在私家网约车司机总数量和出租车市场覆盖度在平台开放策略选择时起到关键作用；平台开放并不总是能增加出租车整体利润和社会福利；出租车订单开放策略下，存在使得出租车总利润与社会福利最大化的出租车数量特定值。

Considering that ride-sourcing platforms pay taxi drivers the same rate as private car drivers or charge a commission on taxi orders to open the platform, this study examines the opening strategy selection of ride-sourcing platforms. By analyzing the four cases of non-opening, opening ride-sourcing order, opening taxi order, and mixed opening, the profit models for ride-sourcing platforms are constructed by using operational optimization methods, respectively. The optimal decisions for all scenarios are obtained by maximizing platform profits. The results show that all four strategies may be optimal, and the total number of potential private ride-sourcing drivers in the market and the coverage of taxi market play a key role in the selection of platform opening strategies. Platform opening does not always increase the overall profits of taxis and social welfare. Under the strategy of opening taxi order, there is a specific value of the number of taxis that maximizes the total profits of taxis and social welfare.
