Cybersecurity has become a crucial factor in determining foreign direct investment (FDI) flows in an increasingly digitalized world economy. Governments all around the world have implemented cybersecurity laws to protect national security, preserve data privacy, and reduce cyber threats as cross-border data flows increase and digital infrastructure becomes essential to international commercial operations. Foreign Direct Investment (FDI) flows may be impacted by these policies’ compliance costs and regulatory uncertainty, even though their goal is to establish a secure investment environment. The dual effects of cybersecurity rules on foreign direct investment (FDI) are examined in this research article, which looks at both their beneficial role in building trust and their ability to discourage investment through higher costs and restrictions. This study investigates the connection between cybersecurity laws and how they affect international investment choices. Foreign investors face both possibilities and problems as nations fortify their legal frameworks to safeguard sensitive data, vital infrastructure, and digital ecosystems. Strong cybersecurity regulations, on the one hand, promote a stable investment climate by lowering the risks of data breaches, intellectual property theft, and cyberattacks. However, legislative fragmentation among jurisdictions, strict compliance standards, and data localization laws can raise operating costs and make it more difficult for international corporations to enter the market. Using a comparative method, the paper examines cybersecurity regulations in both industrialized and developing nations to see how they affect foreign direct investment inflows. It emphasizes how investor impressions are greatly influenced by regulatory clarity, openness, and worldwide harmonization. The long-term effects of emerging trends on international investment patterns are also assessed, including digital sovereignty, cross-border data restrictions, and changing international standards.
