Price competition is a form of competition that relies on low price to win market, occupy market and defeat competitors. When the products produced by one country or enterprise and another country or enterprise are the same or no difference in performance, utility, style, decoration, services provided, reputation of producers, advertising and so on, a country or an enterprise can only attract customers by selling products at a price lower than its competitors, so that their products can have a market. The difference of product function or appearance can offset the effect of competition to some extent. In fact, plagiarism often occurs in China's foreign trade enterprises, which undoubtedly makes enterprises fall into vicious price competition.
