Abstract: Based on the external demand shock, the paper discusses the relief of the city resilience to the external demand shock and the relationship between the external demand shock and the city export. The results are as follows: The external demand shock results in the biggest decrease of the export volume and variety in small cities, followed by medium-sized cities and big cities; The external demand shock decreases the number of the export destinations of big and medium-sized cities, but has no significant impact on small cities. The external demand shock has a significant negative effect on the export volume of all the cities, which is the most significant in cities of central areas, followed by those in the east and the west; The external demand shock significantly decreases the export varieties and destinations of cities in the east and central areas, but has no significant effect on cities in the west. City economic resilience can effectively relieve the negative impact caused by the external demand shock on the city export.
