摘　　要：针对移动工作支持系统这一新兴事物,以具有移动工作经验的在职员工为样本,在任务—技术匹配模型(TTF)和技术接受模型(TAM)整合的视角下,对影响用户使用移动工作支持系统意向的因素展开研究。研究发现,移动工作所具有的移动性、地点依赖性和时间紧迫性正向影响用户对于移动工作支持系统与移动工作之间匹配性的感知,而这种匹配性连同移动工作支持系统自身的功能表现、用户对移动工作支持系统的感知有用性和感知易用性对用户的使用意向产生正向影响。Because of task characteristics and the wide application of information and communication technology, employees spend about 20% of their working time under the mobile working condition. For this reason, an increasing number of organizations start to develop and use the mobile work support system. The practice shows that a well-designed mobile work support system can dramatically promote the efficiency and effectiveness of mobile work with the premise that employees have good intention to use the system. Therefore, a research on users＇ intention to use mobile work support system is meaningful. TAM （Technology Acceptance Model） is one of the most popular theories in information system research which explains about how users come to accept and use an information technology. TAM asserts that perceived usefulness and perceived ease of use determine an individual＇s intention to use a system. TAM model does not consider the interaction between technology and task. Different from TAM, Task-technology fit （TTF） theory is based on the relationship between task and technology and holds that the usage of new technology depends on the match between tasks characteristics and the capabilities of the adopted technology. Actually, both technology characteristics and task-technology fit have positive impact on the usage of new technology. In consideration of these relationships, this study constructs an integrated model to examine the usage of mobile work support systems. In the study, we firstly analyze the characteristics of mobile work and categorize them into mobility, location dependency and time criticality. Secondly, this paper proposes a conceptual model of usage intention from the perspective of integration. Finally, an empirical study is used to validate the proposed conceptual model. Data was collected from 283 Chinese employees and analyzed with the structural equation modeling method. This paper finds that mobility, location dependency, and time criticality of mobile work have positive effect on users＇
