Research on the International Relevance of China’s Economic Policy Uncertainty

Rongxia LÜ, Xiaojing ZHOU


Currently facing a complex international environment, the world faces instability and uncertainty, and the world ’s economic growth momentum is inadequate. Facing environmental instability in various aspects, in order to promote sustainable economic development, governments of various countries are also implementing policies. There is a large uncertainty. Based on the economic policy uncertainty index, this article deeply studies the correlation between the uncertainty of China's economic policies and the uncertainty of economic policies of the world's important economies, and draws the following conclusions: In terms of correlation, when major historical events occur, the economic policy uncertainty index of each country has increased significantly. Secondly, in terms of targeted correlation, the economic policy uncertainty of each country is not completely independent and will be affected by other countries. Among them, the United States and China have the highest autonomy index and have the greatest impact on other countries. France and Germany have less influence on other countries and are more affected by other countries.
