[Purpose/significance] This research aims to explore the influence mechanism of privacy disclosure inten? tion of young elderly under the background of aging-friendly retrofit, and provide suggestions for further promoting re? form and protecting the rights of the young elderly. [Method/process] Combined with privacy calculus theory, PLSSEM was used to analyze the influencing factors of young elderly's perceived benefits and perceived risks, and to clari? fy its mechanism on privacy disclosure intention. [Result/conclusion] The results show that personalization, procedur? al fairness and information control positively affect the perceived benefits of the young elderly, and then promote their intention to disclose privacy.
