Digital innovation has already disrupted numerous industries and is challenging extant theories about innovation. However, until now there is no comprehensive review that systemizes the current state of knowledge on digital innovation. Since publication rates on digital innovation increased fivefold since 2015, it is especially important to understand how the field is developing. The purpose of this paper is to provide an overview on how the field has developed, identify under-researched topics and under-used methods to guide future research. In our structured literature review, we systemize the findings by dif-ferentiating between two dimensions - digital innovation as a process and as an outcome. Furthermore, we explore determinants of digital innovation by taking three different levels of analysis into consider-ation: individual, organizational and environmental. By including extant research until today, we pro-vide a comprehensive summary on current knowledge on digital innovation and identify opportunities for future research.
