What term refers to the worldwide integration of economic, financial, trade, and communication systems?

The term that refers to the worldwide integration of economic, financial, trade, and communication systems is globalization. This concept encompasses the way in which businesses and other organizations develop international influence or operate on an international scale. Globalization leads to the interconnectedness of markets and economies, making it easier for goods, services, information, and cultural exchanges to flow across borders.

In contrast, nationalization is a process where private assets are transferred to public ownership, typically involves a single country's approach to its own economy or resources. Localization focuses on adapting products or services to meet the needs and preferences of local markets, which is often the opposite concept of globalization. Internationalization is a process companies undertake to enter foreign markets but does not capture the broader systemic integration of various systems worldwide to the extent that globalization does.
