This study aims to provide a better picture of factors affecting personal information
disclosure in online shopping. Online survey data from 212 online consumers of five
largest Chinese online companies are used to test the proposed model. We conduct
structural equation modeling with partial least squares to analyze the measurement and
structural models. Our findings show that social influence and perceived effectiveness
have significant and positive impacts on personal information disclosure. Information
privacy concern has a significant and negative impact on personal information disclosure.
However, no significant relationship is found between self-efficacy and personal
information disclosure. We also find great differences in consumers’ behaviors when
classifying consumers according to the type of online companies. Our research extends
the Theory of Reasoned Action, Protection Motivation Theory, and prior research to
discuss four antecedents of personal information disclosure intention. This study is an
explorative one that better explains consumers’ decision-making behaviors in online
shopping
