The Influence of ESG, SRI, Ethical, and Impact Investing Activities on Portfolio and Financial Performance—Bibliometric Analysis/Mapping and Clustering Analysis

This paper aims to examine the publication metrics of literature related to the influential aspects of ESG (environmental, social, and governance), SRI (socially responsible investing), ethical, and impact investing on the portfolio and financial performance literature. It also seeks to identify major patterns and core themes in this topic and draw lessons from the past literature for future directions. Data from the SCOPUS database were used in this study. The ‘biblioshiny’ R package, also known as ‘bibliometrix 3.0’, was employed to conduct bibliometric analysis, utilising mapping and clustering techniques on 260 articles, in order to distil the comprehensive knowledge and identify emerging trends in ESG, SRI, ethical, and impact investing. The thematic map classified the ESG, SRI, ethical, impact investing and performance relationship themes into four categories of themes: niche themes (SRI, engagement and ESG), motor themes (corporate financial performance, corporate social performance, ESG, ESG factors, sustainability, performance, integrated reporting, gender diversity, and board size), emerging or declining themes (social responsibility, environmental
performance, socially responsible investment, ethical investment, and SRI), and basic or transversal themes (financial performance, corporate social performance, ESG performance, environmental, social, and governance). Socially responsible investing, engagement, and ESG imply a position between niche themes and a highly developed topic/emerging or a decreasing theme, while the impact of COVID-19 on sustainability and financial performance implies a position between a highly developed topic/emerging or decreasing theme and a basic theme. The findings contribute to the enhanced understanding of ESG, SRI, ethical, impact investing and performance, which are crucial for an efficient capital market in promoting sustainability and sustainable development. The study offers vital practical implications and future research directions.
