Abstract: China is featured by a large population and limited per capita arable land，and smallholder farmers need to be linked with new agricultural business entities represented by large farms，family farms，farmer cooperatives，and agricultural companies to achieve modern agriculture However，do these new agricultural business entities have inclusive effects on the income of the surrounding smallholder farmers? Further analysis is still needed Using the Chinese Family Database which contains data from a comprehensive survey in 2019，this paper analyzes the effects of new agricultural business entities on the income and income inequality of smallholder farmers，and examine the inclusiveness and mechanisms of the effects 
The empirical results show that the development of new agricultural business entities significantly increases agricultural business income and total income of smallholder farmers，and meanwhile reduces the income inequality among smallholder farmers The effects of new agricultural business entities on the agricultural business income and total income are inclusive of farmers with different levels of human，material，and social capital Even more，the income increase effects are larger for farmers featured by lower income levels New agricultural business entities can promote the income of smallholder farmers through mechanisms such as promoting land circulation，reducing land fragmentation，adjusting planting structure，improving mechanization，and providing technology training
The main contributions of this article are threefold：First，while most current research focuses on the role of one specific type of entities，this article investigates the impact of various types of new agricultural business entities on the agricultural business income and total income of smallholder farmers Second，this article uses the Kakwani index to reflect the degree of income inequality，and examines the inclusive effects of new agricultural business entities for smallholder farmers with different ages，education，income，and informatization levels，and social relationship networks Third，this article adopts both traditional and heteroscedasticitybased IV methods，PSM，and quantile regression methods to reduce the estimation bias and improve the accuracy of the conclusions
