许多学者认为，地理邻近在人类互动中的重要性已经被互联网的使用所削弱，而其他人则不同意这一观点。研究已经注意到网络空间和真实的空间中的距离衰减效应，表明交互发生的交互数量与交互者位置之间的距离成反比关系。然而，这些研究很少提供强有力的证据来表明距离对网络空间中互动的影响，也没有量化网络空间和真实的空间之间距离摩擦量的差异。为了填补这一空白，本研究使用了大量的社交媒体数据（Twitter），以定量的方式比较了距离衰减对网络空间和真实的空间之间人类互动的影响。为了估计网络空间和真实的空间中的距离衰减效应，对每个空间中的交互距离衰减函数进行建模。在这项研究中，估计网络空间中的距离衰减可以帮助预测通过社交媒体跨越空间的信息流的程度。衡量思想通过社交媒体传播的程度对基于位置的服务的用户、政策倡导者、公共卫生官员和政治活动家都很有用。
Many scholars have argued that the importance of geographic proximity in human interactions has been diminished by the use of the Internet, while others disagree with this argument. Studies have noted the distance decay effect in both cyberspace and real space, showing that interactions occur with an inverse relationship between the number of interactions and the distance between the locations of the interactors. However, these studies rarely provide strong evidence to show the influence of distance on interactions in cyberspace, nor do they quantify the differences in the amount of friction of distance between cyberspace and real space. To fill this gap, this study used massive amounts of social media data (Twitter) to compare the influence of distance decay on human interactions between cyberspace and real space in a quantitative manner. To estimate the distance decay effect in both cyberspace and real space, the distance decay function of interactions in each space was modeled. Estimating the distance decay in cyberspace in this study can help predict the degree of information flow across space through social media. Measuring how far ideas can be diffused through social media is useful for users of location-based services, policy advocates, public health officials, and political campaigners.
