There　are　problems　of　decision　making　for　the　development　level　of　rural　E-commerce　with　multi-dimensional　preference　and　consideration　of　decision　maker＇s　psychological　behavior.　Aiming　at　the　problems,　a　multidimensional　preference　decision　making　method　is　proposed　based　on　prospect　theory.　Firstly,　the　development　level　evaluation　problem　of　rural　E-commerce　is　described,　and　the　comprehensive　prospect　value　of　alternatives　is　computed.　Then,　the　consistency　measure　and　inconsistency　measure　of　objective　ranking　and　decision　maker＇s　preference　based　on　prospect　theory　are　defined.　Furthermore,　a　fuzzy　multi-dimensional　preference　optimization　model　based　on　the　expectation　level　and　tolerance　of　decision　makers　is　established,　the　comprehensive　prospect　value　of　each　alternative　is　calculated,　the　ranking　of　alternatives　is　determined　by　the　comprehensive　prospect　value.　Finally,　the　validity　and　applicability　of　the　proposed　method　are　illustrated　by　analyzing　the　development　level　of　rural　E-commerce　for　every　county　and　city　in　Sanming　City.　©　2020,　Editorial　Office　of　Control　and　Decision.　All　right　reserved.
