The world economy (mainly refers to European and American countries) can start from opening up new sea routes and colonial expansion at the earliest. In the fierce trade competition and colonial struggle, the world market has gradually formed. Subsequently, Britain first started the industrial revolution, and then the industrial revolution also appeared in European and American countries. The great productivity produced by the industrial revolution swept the world into the capital market economy. With the final formation of the capitalist world market, global integration, economy and technology are closely related, and the trend of globalization is strengthening day by day.
