This study investigates the interplay of organizational support, psychological capital (PsyCap), and organizational ethical climate in shaping employee performance within Chinese banks. Organizational support denotes the perception of an organization valuing its employees and investing in their well-being. PsyCap encompasses positive psychological resources facilitating stress coping, goal achievement, and perseverance. Organizational ethical climate reflects shared norms and values guiding ethical behavior within an organization. The research assesses perceived organizational support across institutional, supervisor, and colleague dimensions, measures PsyCap components (hope, resilience, optimism), and evaluates the organizational ethical climate in Chinese banks (individual, social, rule orientations). The study explores relationships between perceived organizational support, PsyCap, and organizational ethical climate, aiming to develop a Human Resource Management Framework tailored to Chinese banking dynamics. Quantitative analysis, employing questionnaires and multivariate statistical methods (descriptive, correlation, regression analysis), uncovers a significant relationship among organizational support, PsyCap, and organizational ethical climate. The findings highlight the interconnectedness of these factors, suggesting that heightened organizational support contributes to increased psychological capital, fostering a positive and ethical organizational climate. The study's outcomes offer valuable insights for enhancing HR practices, cultivating a supportive culture, and promoting ethical behavior within Chinese banks.
