Globalization is the trend toward integrating national economies into a global market through unrestricted trade, open access to markets, and financial flows. As a result of globalization, 40% of world output is produced by the largest 500 companies, and some individual company revenues exceed the GDP of many countries. The growth of multinational corporations has also accelerated, with over 82,000 transnational corporations responsible for most global trade and foreign investment. While globalization offers benefits like increased market access and lower costs, it also faces criticisms such as loss of national autonomy and inequality. Managing globalization to maximize its benefits while mitigating drawbacks requires consideration of both its opportunities and challenges.
