This study aims to examine the effect of liquidity and profitability on firm value with corporate social responsibility as a moderating variable. The population of this study is a company that is included in the LQ_45 list since 2013-2016 with a population of 180 observations. The sampling technique uses purposive sampling with the authors of companies that are always registered in the LQ_45 period I and II for each year and not outliers. The sample of this study was 145 observations. The analysis technique used regression analysis with pure moderator interaction model. The results of the study show that liquidity has a significant negative effect on firm value; while profitability does not affect firm value; and CSR has a significant positive effect on firm value. CSR has no function to moderate the influence of liquidity on firm value; but proven to strengthen the influence of profitability on firm value. This result shows that CSR provides additional incremental information on the firm value.
