Final answer:
The global economy refers to the international spread of trade and commerce across national boundaries.
Step-by-step explanation:
The statement that the global economy refers to the heightened economic regulation of many national markets as they protect themselves from one another is False. The global economy actually refers to the international spread of trade and commerce across national boundaries with minimal restrictions from governments. It is the process of integrating governments, cultures, and financial markets through international trade into a single world market. This interconnectedness of markets can pose both opportunities and threats for countries depending on their ability to compete in the international market.
