Abstract: The application of modern information technology in agriculture and rural areas promotes the integration of “Internet + agricultural machinery services” and is an important path to improve the level of agricultural mechanization. Therefore, it is of great significance to research the impact of Internet use on the adoption of agricultural machinery services. Based on the threephase China Family Tracking Survey (CFPS) data in 2014, 2016， and 2018, XT-Probit model was used to analyze whether Internet use would affect farmers adoption and heterogeneity of agricultural machinery services. The research found that the use of the Internet could significantly improve the farmers adoption of agricultural machinery services. For every 1 percentage point increase in Internet usage, the adoption probability of agricultural machinery services increased by 0.068 percentage points. After the introduction of the instrumental variable method to deal with endogenous problems, consistent conclusions were still obtained; The impact of Internet use on the adoption of agricultural machinery services by males, younger age, and highereducated farmers was more significantly, indicating that the individuals learning and labor ability would affect the effect of Internet use; The influence coefficient of Internet use on the adoption of agricultural machinery services by households without household agricultural machinery was 0.332, which was much larger than that of 0.175 for households with household agricultural machinery, indicating that Internet use was an important means to promote the adoption of agricultural machinery services by traditional small farmers; The use of the Internet on the adoption of agricultural machinery services by farmers in nonplain areas was significantly positive, with a marginal effect of 0.114, which was 0.046 percentage points higher than the baseline model, indicating that Internet information technology has made outstanding contributions to the development of agricultural mechanization in nonplain areas. Therefore, establishing an “Internet+” agricultural machinery service information platform, increasing the construction of Internet infrastructure in rural areas, and strengthening Internet information technology training for farmers are important policy means to support the development of agricultural machinery service industry and promote the process of agricultural mechanization.
