高层管理支持、IT资源与IT吸收的关系研究

在信息系统领域,高层管理支持一直被认为是IT吸收过程中的重要变量。然而,关于高层管理支持与IT吸收的关系却存在着争议,并且先前的研究较少同时考虑高层管理支持和IT资源部署,忽视了IT资源部署对高层管理支持效用的影响。因此,本文基于全球112个样本组织,探讨CEO支持这一高层管理支持通过IT基础设施资源和IT人力资源对IT吸收结果变量IT业务跨越能力的影响。研究结果表明:IT基础设施资源和IT人力资源完全中介了CEO支持和IT业务跨越能力的关系,同时IT基础设施资源负向调节IT人力资源与IT业务跨越能力之间的关系,从而减弱了IT人力资源的中介作用。

An Empirical Study of Top Management Support,IT Resource and IT Assimilation

In information systems field, top management support has always been considered as a critical antecedent in the IT assim ilation process. However, the findings on the relationship between top management support and IT assimilation are contradictory, and various types of IT resources, such as IT infrastructure resources and IT human resources, have not been integrated with top management support in the IT assimilation process. Following upper echelons theory, we argue that a critical type of top management support ( i.e., CEO support) will impact IT business spanning capability which reflects the overall evaluation of IT assim ilation, and this process is mediated by IT infrastructure resources and IT human resources. With the high level of CEO support, the organization may possess a good position deploy various IT resources, which will easily enhance IT assimilation. Based on a survey collected in Europe, Asia and North A m erica, we use PLS to conduct a quantitative analysis. Our results reveal that CEO support has a positive effect on IT infrastructure resources and IT human resources, IT infrastructure resources and IT human resources have positive effects on IT business spanning capability , and the relationship between CEO support and IT business spanning capability is fully mediated by IT infrastructure resources and IT human resources. M eanwhile, our results also find that IT infrastructure resources negatively moderate the relationship between IT human resources and IT business spanning capability. In the theoretical im plications, our research is at an early attempt to apply upper echelons theory to explaining IT assim ilation, which extends the range of the application of upper echelons theory. In the practical implicatio n s, our research helps IT executives to understand the relationship between top management support, IT resources and IT assim ilation, thus developing a better IT strategy to enhance the level of IT assimilation.
