Abstract: Under the digitized background characterized by hyper-competition and transparency, the realization of e-business value has become a new subject for academic circles. Previous studies pointed out that using IT technology could generate firm agility and ambidexterity, thereby increasing revenue and creating value. However, these studies neglected the fact that IT could also realize e-business value through risk control and cost reduction. Based on IT ambidexterity, this paper examined the value creation mechanism of e-business, including the increase of revenue through the e-business ambidextrous capability and reduction of risk and cost of digitization through the use of IT governance. The empirical study of the data of 204 firms confirms that the e-business ambidextrous strategy has a positive effect on the e-business ambidextrous capabilities, and the e-business ambidextrous capability partially mediates the relationship between the e-business ambidextrous strategy and competitive performance. In addition, contractual governance positively moderates the positive relationship between the e-business ambidextrous strategy and e-business ambidextrous capability, while the e-business ambidextrous capability mainly mediates the moderating effect of contract governance in the relationship between the e-business ambidextrous strategy and competitive performance. Finally, relational governance positively moderates the positive relationship between the e-business ambidextrous strategy and the e-business ambidextrous capability, but the moderating role of relational governance on the relationship between e-business ambidextrous strategy and competitive performance does not exist, thus relational governance does not mediate the moderating effect of relational governance in the relationship between the e-business ambidextrous strategy and competitive performance.
