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.

Key words: agricultural and rural digital economy, agricultural productive services, mechanism research, mediation effect, regional heterogeneity

摘要： 农业生产性服务业是农业现代化转型的基础，农业农村数字经济的发展能为农业生产性服务业提供新的动能，有利于农业现代化的实现。在测度农业农村数字经济的基础上，利用中国31个省（自治区、直辖市）的面板数据，通过固定效应模型与中介效应模型实证研究农业农村数字经济对农业生产性服务业的影响机制。结果表明：固定效应模型下农业农村数字经济系数为0.013 4且显著，说明农业农村数字经济的发展能够促进农业生产性服务业的发展；农业科技创新，农业产业合理化与农业产业高级化在中介检验检验中系数分别为0.033 2、0.035 4、0.018 2且显著为正；异质性条件下，农业农村数字经济对于农业生产性服务业的影响为中部＞东部＞西部；农业发达省份影响较为显著，而对农业不发达地区无显著性影响。
