This study selected data related to agricultural product export in Xinjiang from 2004 to 2022, constructed a high-quality agricultural product export development evaluation index system covering the five dimensions of innovation, coordination, green, open and sharing based on new development concept, and measured the high-quality development of agricultural product export in Xinjiang. The study concluded that the level of high-quality development of Xinjiang agricultural product export improved from 2004 to 2022; the green development index showed an upward trend, the innovation development index rose first and then declined, and the coordination development index, the sharing development index, and the opening development index were in the rising state. Among these, the innovation development index declined significantly, was an important factor restricting the high-quality development of Xinjiang agricultural product export. The green development index was an important factor contributing to the high-quality development of Xinjiang agricultural product export. In addition, the study found that the main factors affecting the high-quality development of Xinjiang agricultural product export also included insufficient export competitiveness and advantages, low dependence on foreign trade and small international market share, high export market concentration, and insufficient ability to drive employment. Based on the above research, Xinjiang should establish an agricultural employment subsidy policy in the new development stage, strengthen the reserve force for agricultural development; continue to promote the innovation and development of agricultural science and technology platforms, cultivate new kinetic energy and new advantages for the development of agricultural products export; and seize the opportunity of the “One Belt, One Road”, realize the high-quality development of agricultural products export.
