Abstract: 【Purpose/significance】In the increasingly serious environment of APP privacy disclosure, the privacy settings provided by
mobile applications provide an important way for users to protect their privacy information. Knowing what factors and how these factors
influence users’privacy setting behaviors is of great significance for enhancing the privacy settings function and improving the aware?
ness of protecting users' privacy.【Method/process】Based on the Protection Motivation Theory and Social Cognitive Theory, seven
variables are selected and questionnaires are used to collect data. Then FsQCA is conducted to analyze the configuration effects among
variables.【Result/conclusion】Variables, such as perceived risk, perceived privacy control, privacy concerns and behavioral benefits
are the necessary conditions for user privacy setting behavior. There are five paths that generate user's privacy setting behavior, such
as lack of privacy policy and driven by negative experience.【Innovation/limitation】This paper focuses on mobile APP users’privacy
setting behavior and uses FsQCA to explore the configuration effects among variables, thus enabling the paper to be innovative in re?
search issues and research methodology. However, there are also some limitations, such as the limited number of research variables
and the sampling method.
