Abstract: The scale of exports of Xinjiang agricultural products to RCEP member countries has been expanding, mainly exporting plant products and food and beverages.Based on the signing of the RCEP agreement, which provided new opportunities for Xinjiang to expand the scale of agricultural exports of RCEP member countries, this study used the agricultural export panel data of Xinjiang, China and RCEP member countries from 2002 to 2020,and used the extended trade gravity model for empirical analysis.The results showed that the export scale of Xinjiang agricultural products was positively correlated with the economic scale, population quantity and institutional quality of member countries, and negatively correlated with relative geographical distance and economic development, and the export potential of Xinjiang agricultural products and RCEP member countries was generally manifested as potential development, with greater potential release space, among which the export potential with Japan, Indonesia and Malaysia was greater, and the export potential of the Philippines and Vietnam was the lowest.It was proposed that Xinjiang should make full use of the favorable conditions of RCEP countries to expand the scale of agricultural exports, focus on the export of advantageous agricultural products, do a good job in RCEP services, and fully tap the potential of agricultural product export trade.
