伴随国际贸易自由化的发展,各国都在降低甚至在一定区域内取消关税,关税壁垒在国际贸易中的作用已越来越小。各国为了保护本国经济的发展,促进本国产品在国际市场上占有更大的份额,纷纷采用各种非关税贸易壁垒的保护措施。 With the development of international trade liberalization, all countries are reducing or even removing tariffs in certain regions, and tariff barriers have become increasingly smaller in international trade. In order to protect their own economic development and promote a greater share of their products in the international market, all countries have adopted a variety of non-tariff trade protection measures.
