The spread of global epidemic and trade protectionism have caused the global economy to face the risk of decline, the cross-border trade and investment activities have shrunk sharply, and the environment of Chinese foreign trade enterprises has deteriorated. In the first half of 2020, China's exports reached US$ 1,098.75 billion, down 6.2% year-on-year, among which the export of clothing and machinery and equipment fell below 16%, making it a severely damaged industry. As a result, various provinces have issued targeted policies and measures on the internal circular economy from export to domestic sales, helping foreign trade enterprises to tide over the crisis from the policy level. However, there are still some problems in the domestic sales model of export enterprises, such as difficult production line turning, unsmooth sales channels, different pain points in domestic and foreign markets, and lack of brand advantages. Foreign trade enterprises must make corresponding adjustments.
