Abstract: It is an important way for improving the socialized service efficiency of agricultural machinery to strengthen the foundation of agricultural material equipment and promote the process of agricultural modernization and rural revitalization. Based on the statistical data of agricultural machinery in China and the Malmquist productivity index model of DEA, the service efficiency of provincial agricultural mechanization service organizations in China from 2011 to 2019 was measured, in order to provide suggestions for improving the service efficiency of agricultural machinery socialization and promoting the development of agricultural mechanization. The results show that the service technical progress of Chinas agricultural mechanized service organizations has increased by 8.5% annually during the nine years, while the service technical efficiency of Chinas agricultural mechanized service organizations has decreased by 7.9% annually during the same period. On the whole, the service efficiency of Chinas agricultural mechanized service organizations shows obvious fluctuation characteristics, and does not increase on the whole. From the regional point of view, only the eastern region realized the improvement of total factor productivity of agricultural mechanization service organizations in the nine years, but the service technology progress of agricultural mechanization service organizations in the eastern and western regions both realized the growth. From the specific situation of each province, there is a positive increase in the service efficiency of nearly half of the provincial agricultural mechanization service organizations, but the difference is great. According to the decomposition of Malmquist productivity index, the 6 provinces that rely on pure technical efficiency and technological progress to promote the regional agricultural machinery socialization service are distributed in the eastern and central regions, but there are 12 provinces that have the loss of pure technical efficiency, technical efficiency and scale efficiency.
