Achieving economic growth is among the most crucial economic objectives for countries, as consistently emphasized in Iran's development plans. In economic literature, one significant factor influencing economic growth is banking credit, which foster growth by creating investment opportunities. Given that access to suitable financial resources is a key driver for the growth and expansion of knowledge-based companies in the economy, the present study, drawing on available statistics, examines the impact of credit granted by government-owned and private banks to knowledge-based companies on Iran's economic growth. Using quarterly time series data of Gross Domestic Product (GDP), the volume of credit granted by government-owned and private banks to knowledge-based companies, bank deposit balances, and gross capital formation during the period 2024-2020, the study employs an Autoregressive Distributed Lag (ARDL) model. The results indicate that banking credit granted to knowledge-based companies have a positive and significant effect on economic growth. Furthermore, the impact of credit provided by government-owned banks is substantially stronger than that of private banks. Overall, other variables, including the ratio of bank deposits to GDP and the capital stock to GDP ratio, also exhibit positive and significant effects on economic growth.
