PurposeThis study focuses on the role of individuals in the innovation management process, by concentrating on leaders and associated behaviors. Specifically, Entrepreneurial Leadership (EL) represent one of the most important fields of innovation management that has become increasingly multifaceted and interdisciplinary with its evolution. Thus, the purpose of this study is to examine a newly emerging research trend with a new lens that is “neuroscience”.Design/methodology/approachThis paper finds an evidence-based roadmap by reviewing the literature with a quantitative Bibliometric Analysis (BA) employing Co-Citation (Co-C) and bibliographic coupling analysis (BcA) to find linkages between the leadership and entrepreneurship literature and the neuroscience literature.FindingsThis study identifies five promising groups of research areas such as the organizational approach, the biological approach, the cognitive approach, the emotional approach and it identify five future research topics such as dynamic skills in innovation exploitation process, the human aspect of leadership, the building process of leadership, the biological perspective of leadership and the application of neuroscience in the ecosystem. Moreover, we find an evidence-based roadmap for stimulating focused EL within the broad topic of innovation management research, to move the field forward.Originality/valueAlthough the past few years have observed the necessity of review studies on the subsets of biological factors, no reviews have sought to bring those different subsets together into a broader biological perspective. This study provides important indications on the interdisciplinary developments between the neuroscience aspects and EL, as a new emerging paradigm within the broad field of innovation management.

Within‐business diversification, product strategies, and competitors' innovative behavior may affect the competitive advantage of business units that operate in the integrated circuit industry. This investigation employs original data about new product introductions and sales from a representative sample of companies. In addition, the study's empirical taxonomy can deal with significant product heterogeneity, which many previous contributions overlook. Econometric analysis shows that corporate diversification within a market segment affects the competitive advantage of constituting units positively. Increased product variety also enables business units to gain a competitive edge over rivals. However, new product introductions by sister units in other market niches impair the performance of a focal unit. A higher propensity to innovate among rival firms also erodes the advantage of a focal unit, whereas positive spillovers arise from other firms' innovations in neighboring market segments.
