Shared mobility options have grown significantly in recent years. However, a major threat to the growing usage of shared-cars is customer churn. Despite companies continually providing rewards to attract customers, factors that contribute to customer churn are not well-understood in the existing literature. This study analyzed one-year transaction data of a one-way carsharing program and applied an extended Cox proportional hazards model to examine these effects. Our results show that: (1) A customer’s retention probability decreased over time with a decelerating rate. (2) Customers were less likely to churn when their frequently-visited shared-car stations were located in neighborhoods with low access to transit or in areas with colleges, railway hubs, or airports. (3) Elderly and male customers had a lower likelihood of churning. (4) The number of coupons was negatively associated with the likelihood of customer churn. (5) The effect of coupons generally increased at first and then decreased after the 130th day. These findings contribute to coupon design and the location choice of shared-car stations. Specifically, we suggest that large-denomination coupons should be split into multiple small-denomination coupons. We encourage companies to locate stations in areas with poor transit access. Meanwhile, coupon issuing strategies can be redeveloped. Offering more coupons to new customers can help maximize the profits of service providers. However, such a strategy is debatable because it invades personal privacy and is unfair for existing loyal customers.

近年来，共享出行的选择已大大增加。但是，客户流失是共享汽车日益普及的主要威胁。尽管公司不断提供奖励以吸引客户，但在现有文献中并未充分理解导致客户流失的因素。这项研究分析了单向汽车共享计划的一年交易数据，并应用了扩展的Cox比例风险模型来检验这些影响。我们的结果表明：（1）随着速度的下降，客户的保留率随着时间的推移而下降。（2）当他们经常访问的共享汽车站位于交通不便的社区或有大学，铁路枢纽或机场的地区时，顾客流失的可能性较小。（3）老年和男性顾客流失的可能性较低。（4）优惠券数量与客户流失的可能性呈负相关。（5）优惠券的效果通常首先增加，然后在第130天减少。这些发现有助于票券设计和共享汽车站的位置选择。具体来说，我们建议将大面额优惠券分成多个小面额优惠券。我们鼓励公司在交通不便的地区找到车站。同时，可以重新开发优惠券发行策略。向新客户提供更多优惠券可以帮助最大化服务提供商的利润。但是，这种策略值得商bat，因为它侵犯了个人隐私，并且对现有的忠实客户不公平。（5）优惠券的效果通常首先增加，然后在第130天减少。这些发现有助于票券设计和共享汽车站的位置选择。具体来说，我们建议将大面额优惠券分成多个小面额优惠券。我们鼓励公司在交通不便的地区找到车站。同时，可以重新开发优惠券发行策略。向新客户提供更多优惠券可以帮助最大化服务提供商的利润。但是，这种策略值得商bat，因为它侵犯了个人隐私，并且对现有的忠实客户不公平。（5）优惠券的效果通常首先增加，然后在第130天减少。这些发现有助于优惠券设计和共享汽车站点的位置选择。具体来说，我们建议将大面额优惠券分成多个小面额优惠券。我们鼓励公司在交通不便的地区找到车站。同时，可以重新开发优惠券发行策略。向新客户提供更多优惠券可以帮助最大化服务提供商的利润。但是，这种策略值得商bat，因为它侵犯了个人隐私，并且对现有的忠实客户不公平。我们建议将大面额优惠券分成多个小面额优惠券。我们鼓励公司在交通不便的地区找到车站。同时，可以重新开发优惠券发行策略。向新客户提供更多优惠券可以帮助最大化服务提供商的利润。但是，这种策略值得商bat，因为它侵犯了个人隐私，并且对现有的忠实客户不公平。我们建议将大面额优惠券分成多个小面额优惠券。我们鼓励公司在交通不便的地区找到车站。同时，可以重新开发优惠券发行策略。向新客户提供更多优惠券可以帮助最大化服务提供商的利润。但是，这种策略值得商bat，因为它侵犯了个人隐私，并且对现有的忠实客户是不公平的。
