policies to prevent economic recession and promote structural transformation in the economy. While these policies have mitigated short-term economic problems, they have also increased economic policy uncertainty. Firms are an inseparable part of the macroeconomy, and economic policies and government actions significantly influence their innovative activities. This study, using panel data from 113 firms listed on the Tehran Stock Exchange during the period 1394-1401, investigates the moderating role of government support in the relationship between economic policy uncertainty and research and development (R&D) investment. The results show that economic policy uncertainty is positively associated with R&D investment, and government support has a significant positive moderating effect on this relationship. Based on the findings, it is recommended that the government increase financial subsidies to help firms amplify the positive impact of economic policy uncertainty on R&D investment
