Online shopping is undoubtedly the most active consumer behavior in modern business society. However, there is no way to completely eliminate the risks associated with online shopping, so every consumer will assess the risk tolerance in the process of online shopping and have a significant degree of trust before they will be willing to purchase. No matter how advanced the technology is, the risk of online shopping cannot be completely eliminated. The viewpoint of this study is to present the fact that 214 online shopping customers' opinions were collected using questionnaires to explore the relationship between trust in perceived risk and purchase intention in online shopping, and to re-examine the psychological nature of online shopping behavior for the practical management of online marketing.
