Abstract: Taking statistical data of Binzhou City from 2009 to 2020 as research sample, constructing agricultural input-output evaluation index system, the BCC model was used to analyze agricultural input and output efficiency． The BCC model analysis showed that comprehensive efficiency（CE）of agricultural input and output in Binzhou was higher, and pure technical efficiency（PTE）was higher than scale efficiency（SE）． PTE had a strong dependence． The overall analysis showed that Binzhou's agricultural input-output efficiency was relatively high, which was greatly affected by scale, and there was a certain degree of investment redundancy and management problems． Investment in agricultural science and technology should be increased to expand the scale of agricultural production．
