This conceptual paper aims to construct an integrated theoretical framework that explores the impact of leadership styles (transformational and transactional) and human resource development policies on human capital efficiency and the retention of national cadres, highlighting the mediating role of organizational culture. Drawing upon contemporary management theories—particularly human resource management and human capital theory—the study conceptualizes how modern leadership practices and strategic HR policies (such as workforce planning, recruitment, training, compensation, and performance appraisal) collectively influence institutional sustainability through enhanced human capital. The paper is situated within the context of the United Arab Emirates, with particular emphasis on the Dubai Police General Headquarters, which is recognized for its institutional excellence and innovation in public service. The model proposed suggests that effective leadership and well-structured HR policies play a vital role in attracting, developing, and retaining skilled national employees, while organizational culture serves as a catalyst that shapes and reinforces these relationships. The theoretical implications of this study aim to inform institutional strategies that enhance talent retention, optimize human capital, and promote long-term organizational performance aligned with national development goals.
