基于脱钩视角的中国与其他G20国家 贸易关系时空演变.

Based on the trade data between China and other G20 countries from 2001 to 2019, this paper analyzed the evolution of bilateral trade pattern, analyzed the interdependence of bilat‐ eral trade by using trade intensity index and HM index, and analyzed the trade decoupling situa‐ tion between China and other G20 countries by using decoupling model and catch-up decoupling model. The results show that: (1) China and other G20 countries show asymmetric trade interde‐ pendence. China's trade intensity with other G20 countries is greater than that with China, while other G20 countries are more dependent on China's market;(2) The trade decoupling relationship between China and other G20 countries has changed from weak negative decoupling to expansionary negative decoupling. The trade sensitivity has decreased first and then increased. It has experienced four evolution stages: weak negative decoupling, expansionary negative decoupling, relative decoupling I and expansionary negative decoupling;(3) The United States and South Korea have achieved absolute catch-up with Japan, and most countries have achieved relative catch-up with Japan and Saudi Arabia. China's economic and trade relations with other G20 countries tend to be negatively decoupled for a long time. The "relative decoupling" of China's economic and trade relations with other G20 countries exists objectively, but it will not be "fully decoupled". China should deepen cooperation in low sensitivity areas with trade decoupled countries, tap the potential of cooperation with trade connected countries, and actively build a "decoupled discourse system" with "adjustment of interaction and dependence" as the core.
