Abstract
This article deals with the evolution of leadership in the corporate business environment by presenting the results of comparative empirical studies conducted in 2008 and 2018. Based on an analysis of empirical research on the 2000 largest global corporations, obtained from the Forbes Global 2000, this work presents the changes that took place over a decade in the characteristics and competencies of contemporary leaders. The results allowed us to identify the desired characteristics, competencies, and character traits of contemporary leaders. In fact, the comparative analysis of these data showed the dynamics of change in the approach of global corporate leaders over the decade. The research results have important implications for the energy sector. Some of the companies participating in the study operate in the energy sector, therefore the opinions of these CEOs indicate significant determinants of modern leadership in this type of enterprise. When analysing the research results on the vision and scope of leadership impact in corporate business, we pointed, among other things, to the assessment of leadership traits, the evolution of leadership activities’ delegation, and the assessment of the importance of managers’ individual action areas and leadership factors.
