Abstract: [Objective] Labor is becoming a main factor of production on the forestry economic growth. This paper attempts to answer the question how the large amount of rural labor force transfer will bring about the farmers' demand of social service on forestry production process(SSFPP). It is great significant to improve the system of the SSFPP.[Method] Based on the survey data of 1 407 households in 8 provinces(regions), this paper used the bivariate Probit model to analyze the impact of labor transfer on the farmers' demand of the SSDFPP.[Result] The impact of the labor transfer degree on the SSFPP was significant. In this paper, the forest services on product process included the forestry seed and cultivation technology service(FSCTS)and the forest insect pest and fire prevent service(FIPFPS).Their influence coefficients were -0.103 and -0.124. The factors, including households and gender of transfer, significantly affected farmers' needs and supply in differences. Charged services guided the forestry socialization services to market-oriented direction, joining forestry cooperatives can better synchronize the relationship between farmers' social service demand and availability. In addition, the population and location conditions of farmers had significant influence on the demand and supply of the SSFPP in different directions.[Conclusion] From the research results, the basic transfer of rural surplus labor have been completed, the number of further transfer is to reduce the farmers demand for SSFPP, which means to reduce the dependency of farmers on forestry management, and affect farmers' forestry production. It is not conducive to the improvement of forestland management efficiency and will also make the forest management to face the risk of being rough again. Therefore,we should further improve the forestry professional cooperatives system, speed up the professionalization and scale of forestry services in order to overcome the shortage of forestry production labor supply problems brought by labor force transfer in the single family, thereby improve the service efficiency and service capabilities of the SSFPP.
