Abstract: Whether the quality of Xinjiang's export agricultural products has been improved is a hot topic shared by policy makers and academic researchers. It has become one of the important issues to be solved in rural revitalization, agricultural modernization and high-quality transformation of agricultural products. Based on the data of Xinjiang export agricultural products trade in 2002-2018, the calculation and analysis of the quality of Xinjiang export agricultural products, this paper uses the LMDI model to decompose the factors affecting the quality of Xinjiang export agricultural products. The results show that the quality of Xinjiang export agricultural products shows a "continuous decline - inverted U type characteristics - non-linear growth" dynamic trend; the dynamic changes in the quality of Xinjiang export agricultural products are demand effect, dependence effect, economic effect, structural effect, intensity The result of the combined effect of five factors. Among them, the demand effect is the main driving force of Xinjiang export agricultural product quality, and the dependence effect is an important driving force. The economic, structural and intensity effects are only 10.13%. Therefore, we should strictly define the power boundary of "government-market", grasp the strategic basis of "market demand", promote the construction of agricultural product quality standard system throughout "pre-production, production, and post-production", and implement the export market diversification strategy so that quality of agricultural exports in Xinjiang could be improved.
