Purpose　In　order　to　improve　the　current　level　of　agricultural　informatization　and　the　large　deviation　of　economic　growth.　Combining　the　cost　input　of　the　green　ecological　environment　and　the　level　of　economic　growth,　the　relationship　model　between　the　level　of　agricultural　informatization　and　economic　growth　is　established　in　the　green　ecological　environment.　Design/methodology/approach　The　authors　establish　an　evaluation　index　system　for　the　level　of　agricultural　informatization　and　calculate　the　total　index　of　agricultural　informatization　under　the　index　system.　Combining　the　cost　input　of　the　green　ecological　environment　and　the　level　of　economic　growth,　the　authors　establish　the　relationship　model　between　the　level　of　agricultural　informatization　and　economic　growth　in　the　green　ecological　environment.　Findings　The　research　results　show　that　the　regression　coefficient　of　determination　including　agricultural　informatization　elements　from　2014　to　2018　is　5.105466,　indicating　that　the　model　fits　well.　The　sum　of　the　variables　is　greater　than　1,　indicating　that　the　mutual　influence　of　agricultural　informatization　factors　is　also　obvious.　The　condition　of　the　hypothesis　test　in　this　study　is　significant　(5%),　which　shows　the　positive　relationship　between　the　elastic　coefficient　of　agricultural　informatization　and　the　elements　of　informatization.　The　results　show　that　the　continuous　advancement　of　the　informatization　process　can　effectively　promote　agricultural　economic　growth.　Originality/value　The　condition　of　the　hypothesis　test　in　this　study　is　significant　(5%),　which　shows　the　positive　relationship　between　the　elastic　coefficient　of　agricultural　informatization　and　the　elements　of　informatization.　The　continuous　advancement　of　the　informatization　process　can　effectively　promote　agricultural　economic　growth.
