The Role of Leadership in a Digitalized World

The final database comprises 54 articles, of which 42 are peer-reviewed papers published by 33 journals, while the remaining 12 papers are conference proceedings (see Table 1).

Regarding the peer reviewed articles in our dataset, most of them stem from Economic, Business and Management (22 articles), and Information and Communication Sciences (10 articles). Only three studies come from the Psychology discipline. As for the sources wherein these articles are published, we count two journals that specifically address the leadership field, such as "The Leadership Quarterly" and "Strategy and Leadership", whereas the remaining 31 other journals are spread across areas such as Economics, Business and Management, Information and Communication Sciences, Psychology, Educational, Heath and Political Sciences. The novelty of the topic and the breadth of journals in which it is published confirms that the field of digital transformation and leadership has garnered interest from several difference disciplines. Such fragmentation of the literature and the different perspectives it has enabled, justifies the need for systematization and alignment of future research.

As for the conference proceedings, half of the articles come from international and peer-reviewed conferences advancing the debate of digital transformation in business, such as the International Conference on Electronic Business, the Scandinavian Conference on Information Systems, the IEEE Conference on e-Learning, e-Management and e-Services.

Among the top five most cited articles in our sample, three come from journals that specifically relate to Human Resources: "Leadership Quarterly" and "Organizational Behavior and Human Decision Processes". In these articles the authors focus on the characteristics of digital leaders in terms of roles and behaviors, stressing the idea that technology is deeply changing the way in which leaders conceive communication and cope with their followers.

As shown in Figure 1, the early 2000s witnessed an initial interest in the topic, when pioneering work began to consider the changes that digitalization brings in the area of leadership and how the concept and practice of leadership are affected by new technologies. However, it has been mostly over the last decade that the topic garnered seesawing attention. It is plausible to assert that the much stronger impact that technological development has had within organizations recently, and the expectation that technological evolution will be even more disruptive in the near future, has accelerated the interest on the topic. Indeed, while all peer-reviewed articles in our sample are from 2000 on, 60 percent were published after 2014. As for conference proceedings, we only considered the contributions presented after 2015 in order to understand how the debate has been developing in recent years.

Regarding the level of analysis (micro vs. macro), the majority of contributions within our sample are at the micro-level (30 articles), while 24 adopt a macro perspective. Within the latter, it is interesting to notice that a considerable number of articles do not pertain to the management field. As to the type of contribution, the majority of articles in our sample (37) are empirical studies, while only a few articles are conceptual. This imbalance reveals there is still a lack of theorization about the impact of technology on leadership. Nevertheless, in the next session we systematize the main theoretical frameworks that have been used to address this topic.
