： The current IS literature treats IT ambidexterity as a single construct, which makes a strong assumption of the simultaneity of IT exploration and exploitation and does not acknowledge the separate effect of each dimension. We take a different approach to investigate IT ambidexterity by respectively examining the antecedents and consequences of IT exploration and IT exploitation. Based on matched-pair data from a field survey of business and IT executives, we find that structural systems of knowing positively influence IT exploitation but have no significant effect on IT exploration, and that the social system of knowing is a significant antecedent of both IT exploration and IT exploitation. Most important, we find that the relationships between the two dimensions of IT ambidexterity and organization agility are contingent on environmental dynamism. IT exploitation increases agility in stable environments but has no effect on agility in dynamic environments, whereas IT exploration has a stronger positive effect on agility in dynamic environments than in stable environments, both significant. This study offers a novel understanding of IT ambidexterity – IT exploration and IT exploitation do not need to be both high to improve agility, and their specific effects depend on environmental dynamism. It improves the current view of IT ambidexterity and makes a significant contribution to IS strategy research and practice.
