Abstract: Comprehensive benefit evaluation system of high standard farmland was constructed from three aspects of economic benefits, social benefits and ecological benefits of high standard farmland construction．Economic benefits, social benefits, ecological benefits and comprehensive benefits of high standard farmland in Qingyang City from 2016 to 2021 were calculated by using entropy weight method and comprehensive evaluation method．Results showed that construction of high standard farmland in Qingyang City was still in initial construction stage, with high social benefits, and economic benefits had not yet been fully demonstrated．It was necessary to further improve ecological benefits through "time for space"．It was suggested to attract social capital investment and expand coverage of infrastructure construction by establishing a high standard farmland construction project fund; accelerate application of agricultural digital technology, and improve digital management level of high standard farmland in Qingyang City; strengthen management and protection of high standard farmland and give full play to long-term benefits of the project; adjust measures to local conditions and promote sustainable development of Qingyang's characteristic and advantageous agricultural industry．
