Abstract: The comprehensive efficiency, technical efficiency and scale efficiency of agricultural products processing industry in Xinjiang from 2010 to 2020 were analyzed through the DEA efficiency model. The empirical results showed that the comprehensive efficiency of Xinjiang’s agricultural products processing industry was invalid in most years in recent years. Compared with the pure technical efficiency, the scale efficiency was the main reason for the ineffectiveness of DEA in agricultural products processing industry in Xinjiang. The DEA projection results showed that the DEA ineffectiveness of Xinjiang’s agricultural products processing industry was mainly reflected in the redundancy of industry assets and liabilities and the lack of industry profits. The main reasons for the ineffectiveness of DEA in Xinjiang’s agricultural products processing industry were the backward technology and equipment, the small number of leading enterprises and the lack of agricultural product processing talents. Based on this, some countermeasures and suggestions were put forward,such as strengthening the support of agricultural products processing industry in Xinjiang,strengthening the park construction, introducing leading enterprises, and cultivating agricultural product processing talents.

Key words: Xinjiang, agricultural products processing industry, input-output efficiency
