Taking 194 family farms in Shandong Province surveyed in 2022 as the research object,the efficiency of family farms was measured using an input-oriented DEA model. Based on four characteristic variable dimensions of family farmers, family farms, agricultural factor inputs, and environment, the Tobit model was used to measure the driving factors of family farm efficiency. The research results indicate that the overall efficiency of family farms in Shandong Province is at a considerable level, with wool for improvement in both pure technical efficiency and scale efficiency. Among the driving factors of family farm efficiency, whether the family farm owner is a party member ,whether the family farm has complete financial records, labor input ,capital input, land input, total liabilities, and the total amount of agricultural production subsidies received by the family farm in the past three years have a significant positive impact on family faint efficiency.
