Growth, Adoption, and Use of Mobile E-Commerce
基于eBay数据，发现移动电商早期采用者多为原有重度网购用户，移动端使用带来持续购买增长，且与PC端替代效应不明显。
We document some early effects of how mobile devices might change Internet and retail commerce. We present three main findings based on an analysis of eBay's mobile shopping application and core Internet platform. First, early adopters of mobile e-commerce applications appear to be people who already were relatively heavy Internet commerce users. Second, adoption of the mobile shopping application is associated with both an immediate and sustained increase in total platform purchasing, with little evidence of substitution from the core platform. Third, differences in user behavior across the mobile applications and the regular Internet site are not yet so dramatic.
