With　the　accelerating　pace　of　technological　innovation,　the　uncertainty　of　technology　development　is　also　increasing,　so　it　is　important　to　estimate　the　trend　of　technology　development　through　scientific　and　reasonable　technology　foresight.　One　of　the　recent　foresight　methods　is　TFDEA,　which　is　based　on　data　envelopment　analysis　and　is　theorectically　an　effective　quantitative　approach　for　technology　forecasting.　However,　the　application　and　research　of　TFDEA　are　relatively　modest.　In　this　paper,　TFDEA　is　applied　in　assessing　and　forecasting　the　quantitative　trends　in　the　mobile　terminal　technology　with　its　effectiveness　tested.　©　2011　IEEE.
