Understanding the attenuation of the accommodation recommendation spillover effect in view of spatial distance
研究了北京Airbnb房源推荐信息的溢出效应是否随地理距离衰减，发现衰减遵循特定模式（有衰减率和衰减点），对信息传播和共享经济研究有参考价值。
Abstract This brief communication aims to reveal whether the recommendation information's spillover effect decays with geographical distance. A unique dataset of Airbnb listings in Beijing is collected to perform an empirical analysis and a model simulation. The results of this study demonstrate that the spillover of listings' recommendation information decays with spatial distance and this decay follows a certain attenuation mode (i.e., has a certain attenuation rate and attenuation point). As one of the first to investigate the attenuation mechanism of information spillover, this communication enriches the current research on information transmission and brings a novel topic to the attention of the community.
