Abstract: It is urgent to improve the conversion rate of agricultural science and technology achievements, because the mismatching of the transform ability of agricultural science and technology achievements and the scientific research strength could result in a large number of idle science and technology achievements. The innovation of incentive mechanism is the key to accelerate the transformation of agricultural science and technology achievements. In order to promote the transformation, we adopted the methods of expert discussion and questionnaire survey from the perspective of the demand of science and technology and extension personnel, studied the present situation and the restriction factors of the transformation of agricultural science and technology achievements in Tianjin, pointed out the problems existing in the incentive mechanism of the transformation, and put forward some suggestions on how to improve the incentive mechanism. We found that: the imperfect incentive mechanism was the main factor restricting the transformation of agricultural science and technology achievements, mainly manifested as the incentive policy was not clear, the management system was not well-established, the incentive target was improper and the incentive means was insufficient; at this stage, the promotion of the innovation and reform of incentive mechanism of agricultural science and technology achievements transformation should be in accordance with the requirements of“innovation-driven development strategy”
