<p style="margin: 0px; padding: 0px; box-sizing: border-box;"><span style="color: #000000; box-sizing: border-box;">“P2P”(peer-to-peer)意即个人对个人。中国作为资源共享的重要市场之一,P2P共享平台将资产、资源、技术的所有者与个人租客进行匹配,所有者可以从中获得利益,个人租客可以获得更有品质的服务。</span></p>

<p style="margin: 0px; padding: 0px; box-sizing: border-box;"><span style="color: #000000; box-sizing: border-box;">那么,当租客发出请求时,所有者应该如何权衡并做出更有利的决策?平台如何通过再分配,让资源得到更充分的利用,并以此让双方获得回报?</span></p>

<p style="margin: 0px; padding: 0px; box-sizing: border-box;"><span style="color: #000000; box-sizing: border-box;">本文作者通过构建一个动态模型,分析中国某汽车共享平台上提供的数据,研究所有者决定接受租客请求时面临的权衡。该模型可以优化物主的决策,并改善平台的运营。模型中考虑了两种不同用户的行为:一类所有者具有前瞻性,会考虑其资源可供租用的状态;而另一类所有者则只考虑眼前的请求,短视地考虑每次决策。</span></p>

<p style="margin: 0px; padding: 0px; box-sizing: border-box;"><span style="box-sizing: border-box;">消费者之间(P2P)的共享市场有助于实现社会闲置资源的共享。当租客对物主的资源发出共享请求时,物主则需要决定是否接受该请求:接受请求可以马上填补资源的闲置期,给物主带来即刻回报,但却降低了物主满足未来对资源有更长时间的请求(更高回报)的灵活性。本文建立了一个模型,来揭示这些共享平台上物主在决定接受租客请求时面临的权衡。该模型可以优化物主的决策,并改善平台的运营。该模型明确容纳了两种类型的物主:一类物主具有前瞻性,会考虑其资源可供租用的状态,而另一类物主则只考虑眼前的请求,短视地做出接受决定。我们将该模型应用于中国一家领先的共享汽车租赁平台的数据集上。结果显示,数据中前瞻型和短视型车主人数各半;女性、经验丰富及年轻的车主更具备前瞻性。结果还显示两类车主对租客有不同的偏好。根据模型的估计结果,我们计算了未来每一天对前瞻型车主的期权价值(即资源一天可用的价值),发现期权价值随时间的推移先增后减。我们进行了两个反事实推论分析。第一项分析表明,如果平台规定最短租期,即便当前的租用条件可带来更高的预期回报,前瞻型物主仍会倾向拒绝请求。第二项分析则表明,随着平台对物主更深入的了解,平台可以通过对租赁请求的优化分配或再分配,大幅提高匹配效率,此举可令绝大部分平台参与者收益。</span></p>
