The development of agricultural productive service with diversification, multiple-layer and multiple-type necessarily requires the socialized, systemized and diversified supply channels, however, different supply channels have different adaptation conditions and further express different effectiveness. Based on the survey of 599 farmer households in Chongqing, Sichuan, Guizhou and Yunnan provinces in southwest China, this paper studies the effectiveness of agricultural productive service supply from the perspective of farmers' income growth and satisfaction. The results show that in ten types of agricultural productive services, the increase of supply channels of agricultural machinery services, agricultural technology popularization service, agricultural product logistics service, agricultural information service, agricultural product quality-checking service and land transfer service is conducive to the increase of farmers' disposable income, but the increase of supply channels of agricultural capital service, agricultural infrastructure service, agricultural financial service and agricultural product marketing service is negatively correlated with farmers' income level, that different supply channels of different types of agricultural productive services have different effects on farmers' satisfaction. We should choose practical supply channels according to the real demand of agricultural production and farmer households in the process of the supply of agricultural productive service and improve the supply channels with lower satisfaction and lower income growth.
