Shandong Province places the work of "agriculture, rural areas, and farmers" in a top priority, striving to create a model for rural revitalization in Qilu. In this context, evaluating the efficiency of the use of financial support for agriculture funds has become the key to comprehensively promoting the rural revitalization strategy. Based on a three-stage DEA(data envelopment analysis）model and evaluates the efficiency using the DEA output values of the fiscal support for agriculture funds in Shandong Province from 2012 to 2021. The calculation results show that the efficiency of financial support for agriculture in Shandong Province is not DEA effective. The reason is that pure technical efficiency and scale efficiency have not reached DEA effectiveness. Finally, policy recommendations are proposed from three aspects: financial fund management, project performance management, and improving the external environment.
