The growth of Airbnb has given rise to changes in tourist behavior and tourism-related industries. However, research on domestic tourism demand (DTD) for Airbnb supply has been limited. Thus, this study uses the autoregressive distributed lag model and Granger causality analysis based on the tourism demand theory to investigate the relationship between Airbnb supply and DTD. Expenditure on tourism-related products, number of visitors, and search volume of tourism destinations are applied to measure the DTD. The results indicate that expenditure has a positive relationship with Airbnb supply in the short term, while the number of visitors and search volume have positive relationships with Airbnb supply in the long term. The findings show differences depending on the types of Airbnb listings and property hosts. Results of the Granger causality analysis indicate Airbnb supply Granger-causes DTD. Theoretical and practical implications regarding tourism demand are discussed based on the findings.

Airbnb 对国内旅游市场重要吗？来自韩国 Airbnb 供需和旅游需求的实证证据

Airbnb 的增长引起了游客行为和旅游相关行业的变化。然而，对 Airbnb 供应的国内旅游需求 （DTD） 的研究一直有限。因此，本研究使用基于旅游需求理论的自回归分布式滞后模型和 Granger 因果关系分析来研究 Airbnb 供应与 DTD 之间的关系。旅游相关产品的支出、游客人数和旅游目的地的搜索量用于衡量 DTD。结果表明，支出在短期内与 Airbnb 供应呈正相关，而访客数量和搜索量与长期 Airbnb 供应呈正相关。调查结果显示，根据 Airbnb 房源和房东的类型，情况会有所不同。格兰杰因果关系分析的结果表明，Airbnb 供应是格兰杰导致 DTD 的原因。根据研究结果讨论了有关旅游需求的理论和实践意义。
