Vertical alliances and innovation : A systematic review of the literature and a future research agenda

Abstract

For this paper, we conducted a systematic review of 116 articles on vertical alliances and innovation published in 35 leading journals between 2000 and 2021, and provide an integrative and in-depth evaluation of the current state of the vertical alliances and innovation literature. Through such review, this article makes three key contributions to the extant literature. First, it provides an integrative overview of vertical alliances and innovation. Second, it maps the depth and scope of the study of vertical alliances and innovation by highlighting the research methods, geographical coverage, industries, and theoretical perspectives deployed by the extant scholarship. Third, it develops a multi-level framework of the vertical alliances and innovation relationship, and discusses the findings based on research linkages between antecedents, mediators, outcomes, and moderators. This framework led us to identify key research gaps and to highlight additional theoretical approaches that may shed light on this important topic, given the growing importance of technological advancement and networks for innovation.
