Given the huge investment and complexity of information technology, it is imperative that boards of directors fully play their important role in promoting firms' IT success. This study aims to investigate the effects of boards of directors' external ties on firms' IT success from the perspective of resource dependence theory.
According to the method of the matched sample comparison group, a total of 576 samples of listed enterprises in three periods were obtained.
Results show that both boards' political ties and boards' business ties have a positive impact on firms' IT success. Environmental uncertainty and the institutional environment play different roles in the relationships between two types of external ties and firms' IT success. Specifically, the results show that the institutional environment can regulate the influence of the political association of directors on firms' IT success negatively. In addition, environmental uncertainty regulates the influence of directors' political association on firms' IT success negatively, as well as the influence of directors' commercial association with firms' IT success.
The external ties were measured by cross-sectional data. And the current study focused on two fundamental types of external ties.
Boards' external ties are studied from both political and business perspectives, and the effects of these two types of external ties on firms' IT success are compared. Additionally, the moderating effects of the institutional environment (macro level) and environmental uncertainty (micro level) in these relationships are investigated.
