Analysis on the influence of green trade barrier’s degree on Vegetable export in China based on gravity model

The United States, the European Union and most RCEP members are important vegetable importers of China. However, in recent years, against the background of anti-globalization, many countries have set up green trade barriers of different degrees for vegetable import. Trade gravity model is a theoretical hypothesis established by Newton's gravitation formula, which is used by economists to explain the problem of determining the flow of trade within a sector. This paper uses the time series data from 2000 to 2019, modifies the gravity model, and uses STATA 12.0 for regression to analyze the impact of the green trade barrier degree of China's main vegetable trade companies on China, and analyzes the changing trend of this influence. Based on the analysis results, we can see the influence of green trade barriers on China's vegetable products is expected to be further reduced, especially after the signing of the RCEP, so China's export will increase, but China's vegetable export direction is going to focus on the east area in the short term. We suggest that China comply with international standards, improve the supply chain and logistics system of agricultural products, enhance the international competitiveness of vegetable products and diversify trade directions.
