中文摘要：

基于任务复杂性和互依性的视角,探讨了内部支持和外部支持对ITSM成功实施的作用机制.通过问卷方式对201名利益相关者进行调查,并采用层级回归分析的方法检验相关假设.结果表明：内部支持和外部支持均对ITSM成功实施产生正面影响,但外部支持对ITSM成功实施的影响大于内部支持对ITSM成功实施的影响;任务复杂性负向调节内部支持与ITSM成功实施之间的关系,同时也负向调节外部支持与ITSM成功实施之间的关系;任务互依性正向调节内部支持与ITSM成功实施之间的关系,同时也正向调节外部支持与ITSM成功实施之间的关系.

英文摘要：

This paper discusses the affect mechanism of internal and external support on the successful implementation of ITSM based on task complexity and task interdependence perspectives and uses hierarchical regression analysis to test the hypotheses through the 201 valid questionnaires. The results indicate that internal support and external support both have significantly positive effect on successful implementation of ITSM, but the former has greater influence than the latter; task complexity negatively moderates the relationship between internal support and successful implementation of ITSM,and it also negatively moderates the relationship between external support and successful implementation of ITSM;task interdependence positively moderates the relationship between internal support and successful implementation of ITSM, and it also positively moderates the relationship between external support and successful implementation of ITSM.
