: Under the background of urbanization, rural hollowing out, and aging, it is increasingly urgent to solve the problem of “who will farm the land” to stabilize the foundation of national food security. The socialized agricultural machinery service undoubtedly provides a feasible solution. From the perspective of land productivity, and based on field survey data from 597 farmers in four major wheat-producing provinces in China, this study applied an endogenous switching regression model. By constructing a “counterfactual” analysis framework, this paper’s empirical analysis showed that the socialized agricultural machinery service had a positive impact on the land productivity of wheat production. At the same time, the impact of socialized agricultural machinery services on land productivity was heterogeneous due to the differences in planting scale, terrain, and concurrent business. It can give full play to the positive influence of socialized agricultural machinery services on stable grain yields and increases. It is necessary to guide and support the effective supply of socialized agricultural machinery services in the key links of food production, and to reasonably guide the main providers of socialized agricultural machinery service to provide high-quality services that meet the production needs of small farmers according to local conditions, so as to promote the organic connection between small farmers and the development of modern agriculture.
