Improving specialized level of agricultural socialized service system is an important support to accelerate agricultural modernization. The construction of agricultural socialized service system has experienced three periods： the exploration of market-oriented reform of agricultural service system， the construction of agricultural socialized service system， and the construction of new agricultural socialized service system， which has become an important part of the road of agricultural modernization with Chinese characteristics. The prominent problems of the agricultural socialized service system are the lack of professional service ability， which is manifested in the following aspects： some public service institutions are "tangible but not real"； the knowledge structure of personnel is lagging behind and seconded for other uses； the service force is scattered and the layout is unreasonable； the service mode is out of the development trend of modern agriculture； the bottleneck of professional upgrading of agricultural service supply is caused by a series of problems， such as the weakness of whole industry chain professional service strength， the unbalanced development of agricultural productive service industry， the imperfect service organization system for smaller farmer households， and the repeated and disordered development of various service platforms. In order to meet the requirements of agricultural modernization in 2035， we must take the initiative to adapt to the evolution trend of agricultural modernization， and according to the ideas of marketization， diversification， integration and scale， pro

mote the formation of a new， convenient and efficient pattern of multi shared agricultural socialized service， which is guided by the government， led by the market， diversified in main bodies， diversified in forms， and benefited from the whole chain， and build the agricultural specialized socialized service system into a breakthrough on the road of agricultural modernization with Chinese characteristics
