Abstract: In recent years,family farms,which are mainly characterized by scale and intensification,have developed rapidly,and the socialized service system of agricultural machinery mainly serving family farms and farmers' agricultural machinery operations has been basically formed.Agricultural mechanization service has significantly reduced production costs,improved production efficiency,increased economic benefits,and achieved an increase in family farm scale returns.Through the introduction of macro policies to cultivate and develop agricultural mechanization social service organizations,the state has directly or indirectly promoted the development of family farms.With the reasonable price mechanism of medium supply and demand market,agricultural mechanization social service can adjust the coordinated development of family farm and agricultural mechanization social service organization to realize the maximization of common interests.Agricultural mechanization service has a direct impact on production and operation cost,yield,profit and other basic factors,and has a microcosmic transmission effect on family farms.Only by formulating systematic macro-support policies,reforming the structure of market supply and demand,attaching importance to the transmission and feedback of factors,guiding the optimization of the structure of agricultural machinery and equipment industry,strengthening the support of subsidies for agricultural science and technology innovation,and strengthening the construction of agricultural machinery service team,can the maximum matching degree of supply and demand of socialized agricultural machinery service be achieved,and mutual promotion and win-win results be achieved.

Key words: agricultural machinery, agricultural mechanization service, agricultural mechanization service, family farm
