To improve the appeal of carsharing, we propose an integrated operation scheme of carsharing and parking-sharing services, where a carsharing operator rents parking spaces from private owners to provide convenient parking options to carsharing users. We examine how the operator's profit and social welfare differ under the existing carsharing-only service scheme and a bundled carsharing and parking-sharing service scheme. In particular, multiple groups of decision makers, i.e., suppliers of shared parking spaces, platform operators, carsharing users and private vehicle users, and interactions among them are modeled in the context of an integrated sharing platform. The properties of carsharing user and private-vehicle traveler choice equilibrium are discussed. The profit-maximizing and social-optimal platform pricing and supply strategies are explored. Numerical examples illustrate that the bundled carsharing and parking-sharing service scheme holds the potential to improve the operator's profit and social welfare.

为提高汽车共享的吸引力，我们提出了汽车共享和停车共享服务的综合运营方案，即汽车共享运营商从私人所有者那里租用停车位，以为汽车共享用户提供便利的停车选择。我们研究了在现有的仅汽车共享服务计划以及捆绑的汽车共享和停车共享服务计划下，运营商的利润和社会福利有何不同。特别是，在集成共享平台的背景下，对多组决策者（即共享停车位的供应商，平台运营商，汽车共享用户和私家车用户以及他们之间的交互）进行建模。讨论了乘车用户和私家车旅行者选择均衡的性质。探索了利润最大化和社会最优的平台定价和供应策略。数值算例表明，捆绑的汽车共享和停车共享服务方案具有提高运营商的利润和社会福利的潜力。
