Effective land scale management is crucial for achieving agricultural modernization in China. However, the current landscape is plagued by practical challenges, including the sluggish growth of land transfer and the hindrance of moderate scale management. Jiangsu Province, characterized by its high economic development and a well-established land transfer market, has successfully addressed these issues through innovative approaches such as land readjustment and the establishment of intermediary organizations. The dataset is based on the 2020-2022 China Land Economic Survey (CLES) database, and it has been organized into three datasets comprising 943 plots, 5923 households, and 114 villages, following standardized procedures. The data content includes information on land use and transfer, as well as scale. The empirical evidence provided by this data set offers valuable insights into land transfer and large-scale operation in Jiangsu Province, thereby serving as a reference for government departments in formulating effective policy interventions.
