This study aims to examine the impact of research and development expenditure on the performance and firm value of companies listed on the Indonesia Stock Exchange during the period 2017-2021. Research and development expenditure is proxied by the natural logarithm of each company's research and development expenditure. The performance of the companies is measured by financial performance indicators, namely Return on Assets (ROA) and Return on Equity (ROE), as well as market performance measured by Tobin's Q. Furthermore, firm value is assessed by the natural logarithm of market capitalization, representing the total market capitalization. Using panel data analysis, the findings indicate that research and development expenditure has a positive impact on both the performance and firm value.
