This paper uses panel data from a total of 137 host countries from 2009 to 2019 to test the impact of the institutional distance between China and the host country on the six indicators on the export trade effect of foreign direct investment and finds that the excellent institutional quality of the host country has a positive regulatory effect on the export trade effect but the export creation effect of China's OFDI will be weakened to a certain extent due to the existence of institutional distance.
