Many　researchers　have　done　great　jobs　in　the　study　of　the　assessment　of　future　market　potential　of　emerging　technology　products,　and　it　has　been　one　of　the　research　hotspots　in　the　field　of　MOT,　while　there　are　still　not　convincing　methods　that　can　complete　the　systematic　analysis　from　the　research　results.　This　study　presents　a　systematic　analysis　method　that　combing　the　subjective　and　objective　methods　of　market　potential　assessment　and　analyzing　the　matching　up　of　the　technology　supply　and　market　requirements,　and　this　is　expected　to　be　the　comprehensive　assess　method　and　with　great　practical　value.　We　also　assess　the　future　market　potential　of　tubular　skylight　system　as　the　specific　example,　and　we　get　the　match　degree　between　the　tubular　skylight　system　and　the　market　demand　product　in　the　end.
