The results of this research state that Profitability (ROA) significantly affects Firm Value (PBV), Liquidity (CR) does not significantly affect Firm Value (PBV), Leverage (DER) does not significantly affect Firm Value (PBV), Corporate Social Responsibility ( CSR) can significantly moderate the effect of Profitability (ROA) on Firm Value (PBV), Corporate Social Responsibility (CSR) can significantly moderate the effect of Liquidity (CR) on Firm Value (PBV), Corporate Social Responsibility (CSR) cannot moderate significantly the effect of Leverage (DER) on Firm Value (PBV).
