Foreign Direct Investment (FDI) plays a crucial role in shaping the economic landscape of India, attracting significant attention from investors, policymakers, and economists alike. As one of the fastest-growing economies in the world, India has been successful in improving its attractiveness to foreign investors through various policy reforms and liberalization measures. The study finds important patterns and connections in the dynamics of FDI inflow by applying quantitative analytical techniques such a regression analysis and correlation analysis. The results of regression analysis highlight the impact of the GDP on FDI inflow, showing a robust positive connection between GDP and FDI inflow. In recent years, there has been a substantial increase in FDI inflows into India across different sectors, such as telecommunications, manufacturing, and services. This surge in FDI can be attributed to the country's large and growing market, skilled workforce, improving infrastructure, and stable political environment. Analyzing the financial flows of FDI into India reveals that a significant portion of inflows comes from countries such as the United States, Singapore, and Mauritius. This diversification of funding sources indicates the global interest in investing in India and leveraging its potential as a key market in the region. The economic impacts of FDI in India are multifaceted and go beyond simply bringing capital into the country. FDI inflows contribute to job creation, technology transfer, skill development, and overall economic growth. Foreign investors bring in expertise, best practices, and access to new markets, which can benefit local industries and enhance competitiveness. Moreover, FDI inflows can also lead to improvements in productivity, efficiency, and innovation within domestic firms through spillover effects. However, it is essential to recognize the challenges associated with FDI in India, such as regulatory complexity, infrastructure bottlenecks, bureaucratic inefficiencies, and socio-political factors. Addressing these challenges requires continuous efforts from the government to further streamline regulations, improve infrastructure, enhance the ease of doing business, and foster a more investor-friendly environment.
