Abstract：Xinjiang is the important wheat production advantage area in China,and the cost-benefit of wheat is very important to farmers' enthusiasm for planting and ensuring food security in Xinjiang.The evaluation of wheat total factor productivity is of great significance to improve wheat production efficiency.Based on the cost-benefit data of China and 12 major wheat production provinces from 2007 to 2023,the study explores the comprehensive efficiency of wheat by SBM(Slack-Based Measure)model.From three dimensions of pure technology efficiency,scale efficiency and pure technology change,the comprehensive efficiency comparison results of Xinjiang compared with the main wheat producing provinces in China were obtained.The results show that:(1)The input-output comprehensive efficiency of Xinjiang wheat reaches 0.989,which is lower than the national average level and ranks 9th among the 12 major production provinces,at a relatively low level,and the comprehensive efficiency has reached the best in only eight years in 17 years.(2)The technological progress is the main driving force for promoting the comprehensive efficiency of wheat in Xinjiang.The pure technical efficiency reaches 1.017,which is higher than the national average,and only lower than the level of the four major wheat production provinces of Shanxi,Shaanxi,Inner Mongolia and Hebei.(3)The scale efficiency is 0.971,which is below the national average level,and higher than the level of the three main production provinces of Shandong,Hebei and Inner Mongolia.It is necessary to strengthen the research and development and application of new wheat varieties cultivation,reasonable dense planting,integration of water and fertilizer,and precision control technology,determine the wheat planting area scientifically and rationally,optimize the layout,and improve the scale efficiency.
