Carbon emission intensity（ CI） was calculated by using the ratio method，while marginal carbon abatement cost（M-cost） was estimated byapplying the shadow price method.A mediation efect model and a Probit model were employed toexploretheimpactandmechanismoffarmlandinfrastructureconstructiononcarbonemisionreductioninricecultivation.Tersults indicated that：farmland infrastructure significantly reduced CI ，with road engineering exhibiting a strongest effect.Green technologies playedamediatingroleintisprocess，amongichpesticidereductionsubstitutiontechnologyandwatersavingiigatiotechology demonstrate significant mediation effects.Field road had a significant inverted“U"shaped impact on M-cost .To accelerate the low-carbon transitionofriceproduction，priorityshouldbegiventopromotingtherenovationandupgradingoffieldroadprojects，stablishingan “engineringagrotegatdissodctionodelandeingmissionductiststdvaeteasedoction of farmland infrastructure.
