Multinational corporations (MNCs) own or control production in multiple countries besides their home country. They have large-scale international operations through things like imports/exports, foreign investments, contract manufacturing, and opening plants abroad. MNCs can benefit host countries by increasing investment, employment, and income as well as transferring technology. However, they may also threaten economic sovereignty, kill local businesses through monopolies, and deplete natural resources. Both home and host countries experience advantages like jobs, exports, and development, but also disadvantages like unfavorable capital flows and neglect of the home country.
