The research investigates manufacturing export effects on Indian GDP expansion rates by examining data from 2000 to 2023. India's goal to develop into a worldwide manufacturing center requires complete knowledge of how export-generated expansion impacts trade policy formation. This research employs time-series data analysis, including Ordinary Least Squares (OLS) regression and Granger causality tests, to assess the relationship between manufacturing exports and GDP. The research examines three primary manufacturing sub-sectors which power the country's export achievements namely automobiles alongside textiles as well as electronics. The study analyzes environmental elements which impact manufacturing exports by examining exchange rate movements and worldwide market conditions and international trade regulations. The research determines whether manufacturing exports drive economic growth or merely respond to GDP expansion by analyzing short-term and long-term effects. The study will establish empirical support for export-led growth ideas, guiding government officials toward better global trading competitiveness policies. The research sets out to deliver strategic recommendations about raising the importance of manufacturing exports for GDP growth through urgent improvements in infrastructure development and economic policy incentives combined with cooperation in global trade blocks. The targeted examination of the manufacturing industry allows this research to deliver a better focused and practical investigation instead of extensive trade and economic development studies. The practical implications of these findings will guide policymakers and inform future research in this area.
