Abstract: In the process of international trade, the problem of the problem of high consumption and high carbonization of agriculture in China has become increasingly prominent. How to improve the relationship between environmental costs and environmental benefits in agricultural export trade has become the key to reduce the high-carbon agricultural exports, which is of great value to the realization of low-carbon agriculture in China. By constructing the MRIO model, and using the continuous-time non-competitive input-output table of comparable prices from 2007 to 2019, the embodied carbon in the added value of agricultural exports in the major countries of Asia, North America and the European Union was measured and structurally decomposed. The research showed that the transformation of agricultural export trade in China has achieved preliminary results, and the embodied carbon in the added value of agricultural exports decreased rapidly, but it was still higher than that of the major developed economies in the world. The sharp decline of the agricultural carbon emission intensity was the key factor influencing the embodied carbon in the added value of agricultural export trade in China. Therefore, the countermeasures were put forward including rationally formulating the policies to optimize the scale of agricultural exports, appropriately increasing the agricultural trade barriers, reducing the transfer of embodied carbon in the added value of agricultural exports in China from other countries, and enhancing the export competitiveness of some agricultural products with low added value and low emission, improving the comprehensive added value of agricultural exports in China, etc.
