Firm strategic change has attracted increased attention from strategic management scholars over the past few decades.With an aim to review the existing research and to provide a future research agenda,this study presents a multi-level analytical framework of the drivers of a firm's strategic change.Specifically,we focus on the environment-,organizational-,and individual-level factors.Empirical studies at each of the three levels have been thoroughly reviewed.We further discuss the theoretical differences and relationships among the three levels of factors.This study concludes with important theoretical implications for firm strategic change research and also suggests a few future research directions on this topic.
