Analytic hierarchy process (AHP) and expert consultation method are used to determine the evaluation index system and index weight. Suitability effect of the information service system of "Agricultural Science and Technology 110" is taken as the target layer. The five indices at criterion layer are the organizational mode of agricultural information service, the support system of agricultural information resources, the agricultural information transfer system, the capital source of agricultural information service, and the support system of agricultural information service. And the index layer includes the talent team of agent service, the interaction between the subject and object, the accuracy of agricultural information, the convenience of agricultural information transfer, the adequacy of fund, the efficiency in the use of fund, the status of information infrastructure and so on. Evaluation result shows that the information service system of "Agricultural Science and Technology 110" in Sichuan Province is suitable for the rural economic development at present. The major factors restricting the information service system are the lack of continuity, the weak infrastructure of agricultural information infrastructure, and the relatively low education level of agricultural producers. Therefore, we should further explore and improve the operation mechanism of agricultural information service, expand the capital source of agricultural information service, strengthen the construction of agricultural infrastructure, and ensure the continuous operation of information service system.展开更多
