The sharing business model (SBM) has introduced a new type of business model that combines collaborative technologies with idle resources to improve product and service utilization efficiency. However, in recent years, the sharing economy has had a tremendous impact on the tourism business. While some initially suggest that the sharing economy (SE) is beneficial to sustainability, we believe that extensive adoption may have unwanted consequences due to negative cultural effects in tourism. This study uses a thematic analysis to classify SBM's cultural dark side. Using a systematic literature review approach and the PRISMA protocol on 117 eligible papers, we identify ten negative cultural effects: nuisance for local residents, unethical practices, perceived risk, social inequality, customer misbehavior, safety concerns, employee rights violations, lobbying, consumerism, and overcrowding. These negative effects are impacting tourism's cultural sustainability. We also help to develop a framework for SBM's cultural sustainability in tourism. The framework suggests some cultural sustainability strategies, such as affordable and accessible products, the development of a niche market, local empowerment, simple production, and ease of use. We address the theoretical and practical implications, as well as the limitations. Finally, we discussed future research in three major directions.
