移动社交网络作为一类重要的信息通信技术形态，其成瘾性使用已经成为现代管理信息系统研究的重要课题并得到了极大的社会关注。然而，目前对于成瘾的心理与行为界定、作用机理与驱动因素、以及影响后果方面的研究仍存在很大的模糊性，同时研究方法也存在多概念、重描述、少理论、轻实证等问题。本研究拟结合管理信息系统、社会心理学、计算机科学等相关理论与方法，基于不完全理性行为假设，通过数据挖掘、网络调查、设计科学、深度访谈等实证研究方法，系统研究移动社交网络成瘾性使用的心理与行为驱动因素以及负面后果。本项目主要探讨三个方面的内容：（1）根据双重过程理论，提炼成瘾性使用的心理影响因素，并探索移动去抑制性和负面社会影响的调节作用；（2）基于认知偏差改变原理，探讨成瘾性使用的行为改变机制；（3）结合技术应激模型，研究成瘾性使用的行为后果。本研究为信息技术的良性发展提供理论和实际参考，具有较大的理论意义和实践价值。

With the development of information communication and technology (ICT), mobile social network addiction has received a great amount of attention from both scholars and practitioners. However, the consensus on the definition of mobile SNS addiction has not been reached because of various nomenclatures used to explain such behavior in the use of mobile social network. In addition, the few existing studies investigating mobile SNS addiction tend to primarily adopt a conceptual or descriptive approach. Limited comprehensive and theory-driven investigation has been concerned with the mechanism of mobile SNS addiction. Based on the bounded rationality assumption, this project attempts to understand and investigate the antecedents and consequences of users’ addiction behavior by the use of data mining, online survey, design science, and deep interview. Specifically, the purposes of this project are: (1) illuminating the underlying mechanism of mobile SNS addiction on the basis of dual process theory and identifying the moderating effect of mobile disinhibition and negative social influence; (2) investigating the development of mobile SNS addiction behavior with the bias-based cognitive change mechanism; (3) exploring the negative consequences of mobile SNS addiction by extending the stress-strain-outcome model. The results of this project have both theoretical implications on theory building in mobile SNS addiction and practical values on maintaining sustainable development of mobile social networks.
