This article analyzed the effects of Internet usage on the willingness to adopt intelligent agricultural technology among large-scale pig farmers by using the survey data of large-scale pig farmers in Hubei Province and the propensity score matching method in order to promote the popularization of intelligent agricultural technology. On this basis， the Probit model was used to analyze the heterogeneity and influence paths. The results showed that the use of the Internet significantly increased the willingness to adopt intelligent production technologies including intelligent management， intelligent service and safety traceability among large-scale pig farmers. The effect was in the decreasing order of intelligent production technology， intelligent management technology， safety traceability technology and intelligent service technology. The impact of Internet usage on the willingness to adopt intelligent agricultural technology among large-scale pig farmers was heterogeneous. In terms of age， the new generation of large-scale pig farmers tended to use intelligent production technologies， and the older generation of large-scale pig farmers tended to use the other three technologies. In terms of educational background， Internet use had a greater impact on the willingness of low-educated pig farmers to adopt the four technologies compared with high-educated pig farmers. In terms of business scale， small-scale pig farmers tended to use safety traceability technologies， while large-scale pig farmers tended to use the remaining three technologies. The use of the Internet can indirectly and positively affect the adoption willingness of large-scale pig farmers by improving their technical cognition and value perception of intelligent agricultural technology.
