Corporate governance encompasses the mechanisms, processes, and relations by which corporations are controlled and directed. This paper delves into the theoretical foundations and pragmatic underpinnings of corporate governance, offering a comprehensive analysis of the principles and practices that ensure effective oversight and accountability within corporations. The theoretical framework integrates agency theory, stakeholder theory, stewardship theory, and resource dependency theory, providing a multidimensional perspective on governance structures and their implications. Pragmatically, the paper examines the role of boards of directors, executive compensation, shareholder rights, and regulatory frameworks in shaping corporate governance practices. Through a synthesis of empirical research and case studies, the paper highlights best practices and identifies challenges in implementing robust governance mechanisms. The study underscores the importance of ethical leadership, transparency, and stakeholder engagement in fostering sustainable corporate performance and enhancing investor confidence. Ultimately, this book contributes to the ongoing discourse on corporate governance by bridging theoretical insights with practical applications, aiming to guide policymakers, practitioners, and academics in advancing governance standards and practices.
