(2) Trade protection and free trade basically alternate, and the history of liberalism is very short. Before the 1940s of 19, western industrial countries were implementing trade protection measures. 1846 After Britain abolished corn laws, countries began to implement free trade policies mainly from the 1970s of 19. From 65438 to 1970, countries began to implement trade protection policies, and implemented free trade from World War II to the end of 1960s. After 1970s, the new trade policy was gradually adopted by all countries.
(3) Whoever becomes a powerful country will take the lead in breaking trade protection and proposing free trade. 19 The free trade policy in the 1940s was first put forward and implemented by Britain, a powerful country at that time. In the 1940s, the free trade policy was first put forward and implemented by the then powerful United States.
(4) The world economy is easy to implement free trade policies in the growth and prosperity stage, but it is easy to implement trade protection measures when the world economy is facing or in the depression stage.
(5) Liberalism has been dominant for a long time in theory, but in reality, real trade freedom is very short-lived. Liberalism is more often a propaganda slogan, which can be expressed in a vivid sentence: free trade is just a banner held high, but no more countries follow it. (1) For a long time to come, trade protection will remain the support point of trade policies of all countries. Not only developing countries, but also some developed countries will continue to implement trade protection because of fierce competition.
(2) The means of protection are sometimes transparent and extreme (tariff, political, military and other means) and sometimes hidden (various non-tariff barriers).
(3) New ways of protection are constantly emerging (various technologies and green barriers).
(4) Overall protection is enhanced (more trade organizations will emerge continuously).
