In the context of high-quality agricultural development, farmers increasingly  engage in agricultural land use rights transfer(ALURT) to achieve large-scale  operations and improve agricultural production efficiency. However, large-scale  agricultural operations often lead to mechanized production, which may cause  higher carbon emissions, contradicting the principles of green agricultural  development. This study aimed to assess the actual impact of ALURT on the carbon  emission intensity (CEI) of croplands and explore the role of agricultural  large-scale operations in this relationship. To achieve...
