By using survey data from 186 rural farmers in Jilin Province, the influencing factors on farmers’ adoption of maize mechanized harvesting was analyzed by using Logistic model. The results show that gender, technological training, scale of planting, proportion of non-agricultural income, perceived effectiveness, cooperative association membership, the support from the government policies and demonstration projects are positively and significantly correlated with the adoption of maize mechanized harvesting, whereas serious natural disasters plays significant negative effect on it. The policy proposal recommended is enhancement of technological training, acceleration of land integration and circulation, promotion of rural labor transfer, strengthening against disaster ability, as well as governmental supportive policy contributing to acceleration of the spread of corn producing entire mechanization and adoption of maize mechanized harvesting.
