As the organic combination between mobile communications equipment and internet,mobile commerce develops faster and faster.However,consumer's most sensitive information privacy is faced with the threat that consumer's informa-tion is collected and used in an illegal way.Now,we use Technology Threat Avoidance Theory (TTAT)to find how the in-telligent mobile phone consumers face the threat of privacy and what behavior will produce.The results show that,the more serious perception privacy threat of intelligent mobile phone consumers,the more sensitivity to privacy and the stronger threat that consumers will feel;Safeguard effectiveness positively affects avoidance motivation and safeguard cost negatively affects avoidance motivation;The consumer's avoidance behavior is triggered by avoiding motivation,and avoiding motiva-tion is influenced by society,threat perception and safeguard effectiveness.%随着移动通信设备与互联网有机结合所进行的移动商务不断发展，消费者最敏感的信息隐私正面临着非法收集和使用的威胁。基于技术威胁规避理论（Technology Threat Avoidance Theory，TTAT），从消费者规避行为角度对移动商务智能手机终端消费者面对隐私威胁产生的行为进行实证研究，主要得到以下三方面结论：一是消费者对隐私威胁所造成的结果感知越严重、对隐私越敏感，消费者的感知威胁越强；二是消费者对隐私安全保护措施的感知有效性越强、自我效能越高，用户感知规避能力越高；三是消费者的规避行为是由规避动机触发的，规避动机受社会影响、感知威胁和感知规避能力的影响。
