Abstract: In order to measure and improve the efficiency of animal husbandry economic development in Xinjiang, a three-stage DEA-Malmquist index model was used to analyze the input-output efficiency of animal husbandry economic development level in 14 prefectures and cities in Xinjiang during the 13th Five-Year Plan period. The results showed that, from the static analysis, only the counties （cities） directly under Yili Prefecture had unchanged returns to scale during the 13th Five-Year Plan period, showing DEA efficiency. In other areas, because of the decline of scale efficiency or pure technical efficiency, the comprehensive technical efficiency was DEA ineffective, and the scale mostly increased. From the dynamic analysis, Malmquist index was less than 1.000 during the 13th Five-Year Plan period, which indicated that the economic efficiency of animal husbandry in Xinjiang was declining, and the change of technological progress was the main reason that hindered the improvement of economic efficiency of animal husbandry. It should strengthen technical management, take the new animal husbandry management subject as the guide, improve the ability to optimize the efficiency of resource allocation, strengthen grassland protection and construction, and promote moderate scale. Areas with high efficiency level should maintain the advantages of animal husbandry economic development and carry out technology popularization; areas with low efficiency should increase investment in policies, registration systems, infrastructure construction, talents, technology, etc.
