Abstract: Since 2013, China's sorghum imports have increased dramatically due to factors such as the surge in demand for feed substitutes and import quotas policies, which have seriously affected the corn-to-stock reform of the current agricultural supply side. Combined with China's sorghum import and export situation and the analysis of the US sorghum production costs, it showed that the subsidy policy is the main reason for the US sorghum price advantage and competitive advantage, China's sorghum imports have obvious spread-driven characteristics. Therefore, China needs to accelerate the improvement of agricultural support and protection system, and effectively protect the interests of agricultural producers. At the same time, China needs to improve the import and export of agricultural products system, strengthen the management of imports of major agricultural products such as corn, to prevent the surge in imports of major agricultural products on China's agricultural market impact.
