In　this　work,　a　now　prediction　model　for　the　economic　development　of　port　city＇s　agricultural　products　logistics　chain　is　proposed.　Based　on　the　prediction　model,　the　port　city＇s　farm　products　logistics　chain　economic　development　data　were　extracted,　and　the　overall　logistics　chain　economic　development　prediction　evaluation　was　carried　out.　Design　simulation　experiment,　compare　the　design　model　and　big　data　port　city　agricultural　products　logistics　chain　economic　development　prediction　model　error　rate,　prove　the　effectiveness　of　the　study.
