This study examines the causal mechanisms between Corporate Social Responsibility (CSR), Ethical Leadership (EL) and Corporate Values (CV), with Corporate Reputation (CR) acting as a mediating variable, within the restaurant industry. The study is based on a population of 88 restaurants that are members of the Indonesian Hotel and Restaurant Association (PHRI) in the Special Region of Yogyakarta. Using a census method, primary data from questionnaires were analysed using Partial Least Squares–Structural Equation Modelling (PLS-SEM) with SmartPLS 4.0 software. The empirical results demonstrate that CSR has a direct, positive and significant influence on Corporate Value, whilst Ethical Leadership does not show a significant direct influence. Based on the results of the mediation analysis, it was confirmed that Corporate Reputation does not strongly mediate the relationship between CSR and Corporate Value, whereas Corporate Reputation was found to fully mediate the effect of Ethical Leadership on Corporate Value. These findings provide theoretical justification that the integrity of internal leadership must be crystallised into external reputation in order to be converted into market valuation and long-term competitive advantage.
