Abstract:Since the end of the Cold War, the world economic and trade patterns has changed significantly. The first performance is the graduate recession in the US-led western developed countries and the rising in developing countries, led by China. Second, the field of trade in services has developed rapidly, with trend to catch up with trade in goods. The evolution of trade rules has gradually shifted from multilateral to bilateral and regional trade. In terms of the development of agricultural international trade, because agriculture itself is greatly influenced by resources endowment and environmental elements, short-term agricultural pattern of international trade will not change. The United States remains the world's first agricultural superpower, and this trend is stable. At the same time, agriculture in the BRICS countries, led by Brazil, keep rising and plays an increasingly important role on the world stage. In the post-epidemic era, the international agricultural market will fluctuate greatly, and the supply-demand relationship, market structure and price level of agricultural products will change accordingly, which will have a huge impact on countries with a high degree of dependence on agricultural trade, while countries with a low degree of dependence on agricultural trade will be relatively less affected.
