Abstract: Farmers'' income is both a basis and a barometer of rural economic development. Agricultural management income is an important part of farmers’income. Based on the survey data of five suburban counties in Tianjin, this paper uses the regression method to analyze the main factors influencing farmers'' operating income. The results show that the sustained investment of production factors and industrial structure type have a significant positive impact on farmers’operating income, while science and technology training tend to be formalistic and have a significant negative impact on it; regional position and farmers’educational level have no significant effect on operating income; new linking modes between production and marketing do not increase the bargaining power of farmers, and show no income increasing effect. The study suggests accelerating the land transfer, implementing structural adjustment policies, strengthening scientific and technological innovation and promotion, innovating production and marketing convergence mode and etc., to promote the level of farmers'' scale management and improve agricultural management income.
