Globalization refers to the increasing integration and interdependence of national economies through cross-border movement of goods, services, technology and capital. It involves both economic and social effects as barriers to international trade and cultural exchanges are reduced. Key aspects of globalization include the expansion of international trade, growth of multinational corporations, increased capital flows between countries, and the spread of technology and culture to new parts of the world. While globalization opens new markets and opportunities for businesses, it can also face objections related to issues like outsourcing and loss of domestic jobs. Overall, globalization affects both businesses and societies in complex ways.
