2018년 세상에서 가장 GDP가 높은 나라는 어디인가?
The United States is the world's largest economy with a GDP of approximately $19.39 trillion, notably due to high average incomes, a large population, capital investment, moderate unemployment, high consumer spending, a relatively young population, and technological innovation. Tuvalu is the world's smallest national economy, with a GDP of about $32 million, because of its very small population, a lack of natural resources, reliance on foreign aid, negligible capital investment, demographic problems, and low average incomes.
