Abstract: The agricultural productive service industry is the foundation of agricultural modernization transformation, and the development of agricultural and rural digital economy can provide new momentum for the agricultural productive service industry, which is conducive to the realization of agricultural modernization. Based on the measurement of agricultural and rural digital economy, the impact mechanism of agricultural and rural digital economy on agricultural productive service industry is empirically studied through fixed effect model and mediation effect model using panel data from 31 provinces (autonomous regions and municipalities directly under the central government) in China. The results show that the coefficient of agricultural and rural digital economy under the fixedeffect model is 0.013 4 and significant, indicating that the development of agricultural and rural digital economy can promote the development of agricultural productive service industry, and the coefficients of agricultural scientific and technological innovation, agricultural industry rationalization and agricultural industry advanced are 0.033 2, 0.035 4 and 0.018 2, respectively, and are significantly positive. Under heterogeneous conditions, the impact of agricultural and rural digital economy on agricultural productive service industry is central>eastern>western. The impact of agricultural developed provinces is more significant, but there is no significant impact on agricultural underdeveloped areas.
