Bike sharing has enriched the tourist experience while posing hidden risks to tourist attractions. However, the exact impact of bike sharing around tourist attractions on the tourist experience remains under-researched. Using data on tourist attractions and bike sharing collected from TripAdvisor and Divvy, and employing a time-varying difference-in-differences model, the main objective of this study is to investigate the effect of bike sharing stations on tourist satisfaction with nearby attractions and identify key moderating factors behind this impact. Results show that bike sharing stations exert a significant and positive effect on tourist satisfaction with nearby attractions; an attraction's walkability score and central business district location are significant moderators. These findings enhance the understanding of customer behavior within the growing sharing economy, especially the relationship between bike sharing and tourist behavior. This study also offers implications for tour operators, attraction managers, bike sharing enterprises, and urban planners.

共享单车在丰富游客体验的同时，也给旅游景区带来了隐患。然而，旅游景点周围共享单车对旅游体验的确切影响仍有待研究。本研究的主要目的是利用 TripAdvisor 和 Divvy 收集的旅游景点和共享单车数据，并采用时变倍差模型，调查共享单车站点对游客对附近景点满意度的影响，并确定这一影响背后的关键调节因素。研究结果表明，共享单车站点对游客对附近景点的满意度具有显着的正向影响；景点的步行适宜性得分和中央商务区位置是重要的调节因素。这些发现增强了对不断发展的共享经济中客户行为的理解，特别是自行车共享与游客行为之间的关系。这项研究还为旅游经营者、景点管理者、自行车共享企业和城市规划者提供了启示。
