Abstract

The global financial system stands at a critical juncture, facing simultaneous pressures from climate change, social inequality, and governance failures that threaten long-term economic stability. In this context, institutional investors have emerged as pivotal actors in the transition toward sustainable finance, wielding unprecedented influence over corporate environmental, social, and governance (ESG) practices. While existing literature has established correlations between institutional ownership and ESG performance, the mechanisms through which investors actually shape corporate behavior remain inadequately understood. Traditional approaches have predominantly relied on linear regression models that treat institutional investors as homogeneous entities, overlooking the complex network dynamics and strategic interactions that characterize real-world influence processes. This research breaks from convention by developing a novel computational framework that captures the multidimensional nature of investor influence on corporate sustainability. We conceptualize the financial ecosystem as an evolving network where institutional investors and corporations engage in continuous negotiation over ESG standards. Our approach integrates three methodological innovations: dynamic network analysis to map influence pathways, natural language processing to extract ESG commitments from corporate communications, and machine learning to identify tipping points in corporate resistance to sustainability initiatives. The central research questions guiding this investigation are threefold. First, how do different categories of institutional investors vary in their capacity to influence corporate ESG practices, and what investor characteristics determine this influence? Second, through what mechanisms do institutional investors coordinate to amplify their individual impact on corporate sustainability? Third, what conditions trigger rapid, widespread adoption of ESG standards across corporate networks, and can these transitions be predicted? Our findings challenge several established assumptions in the sustainable finance literature. We demonstrate that investor influence operates not merely through ownership stakes but through strategic network positioning and coalition-building. The research reveals that universal owners—institutions with highly diversified portfolios that effectively own slices of the entire economy—possess unique leverage to drive systemic change. Furthermore, we identify specific threshold effects where corporate resistance to ESG initiatives collapses, creating cascading adoption of sustainability standards across industry sectors. This paper makes both theoretical and practical contributions to the field of sustainable finance. Theoretically, we develop a new framework for understanding investor influence that accounts for network dynamics and strategic coordination. Practically, we provide investors, corporations, and policymakers with tools to map influence pathways and identify leverage points for accelerating the sustainability transition. The insights generated have significant implications for addressing pressing global challenges, from climate change mitigation to inequality reduction, by harnessing the power of financial markets to drive positive social and environmental outcomes.
