Leadership Diversity, Governance Quality, and Responsible Innovation in European Industrial Firms: An Integrative Literature Review

Abstract

The objective of this paper is to integrate fragmented research on leadership diversity, governance quality, and responsible innovation in European industrial firms and to explain the governance mechanisms through which different dimensions of leadership diversity may shape responsible innovation. Existing research has generated valuable insights into diversity and innovation, diversity and ESG-related disclosure, and governance and responsible innovation, but these streams remain insufficiently integrated and often rely on different conceptualisations, levels of analysis, and outcome measures. Accordingly, the review asks: how do specific dimensions of leadership diversity shape responsible innovation in European industrial firms, and through which governance mechanisms is this relationship enabled or constrained? To answer this question, the paper adopts an integrative review design suited to a fragmented field combining empirical, conceptual, and meta-analytic studies. Drawing on peer-reviewed literature indexed in Scopus and Web of Science, the review applies transparent selection criteria and synthesises the final corpus through a mechanism-based thematic analysis. The review identifies three recurring mechanisms across the literature: cognitive expansion, governance filtering and integration, and legitimacy signalling. It argues that leadership diversity does not influence responsible innovation in a direct or uniform way. Instead, its effects depend on which diversity dimensions are present, how governance structures and processes translate heterogeneous perspectives into accountable strategic decisions, and how strongly the European institutional context links innovation to legitimacy, disclosure, and sustainability expectations. The paper contributes an integrative conceptual framework that positions governance quality as the key translating mechanism between leadership diversity and responsible innovation and highlights implications for future empirical research.
