Transnational corporations (TNCs) play a key role in globalization through their global production networks and ability to adapt products for local markets. TNCs take advantage of economic liberalization policies that encourage foreign investment by outsourcing and offshoring production to reduce costs. They create complex global supply chains and spread the effects of globalization through offshoring factories and outsourcing components to contractors around the world. TNCs also engage in "glocalization" - adapting products to local customs and tastes, like McDonald's offering vegetarian options in India, to develop new markets.
