本研究以政治學家伊斯頓（David Easton）「政治系統動態回應模型」觀點切入，探討總體環境因素如何影響台灣中產階級的流動。由1980年代美國成功的經驗得知，政府應積極營造自由經濟環境（如TIFA、ECFA、FTA與鮭魚返鄉），進而提出有利台灣本身的產業政策（如科技化服務業與發展中堅企業），教育政策（如落實技職教育與產學合作）應確實配合產業政策與專職訓練的強化，讓Y世代對未來有個夢想。假如政府部門能有所作為，預估台灣2028年始能恢復經濟力，進而中產階級向下流動比率就會減緩，抑或降低。

This study was based on the dynamic response model of a political system proposed by the political scientist David Easton to investigate the effect that overall environmental factors had on the flow or mobility of the middle-class in Taiwan. Based on the successful experience of the U.S. in the 1980's, we know that governments should be actively involved in the development of a free economic environment (such as TIFA, ECFA, FTA, and the ”Returning Salmon” project). They should also propose industrial policies that are beneficial to Taiwan (such as the science and technological service industry and the development of medium-sized companies). Educational policies (such as the implementation of technical and vocational education and industry-academy cooperation) should be correlated with the strengthening of industrial policies and specialized training to enable the Y-generation to establish ideals for the future. If government departments can effect action, Taiwan is estimated to be able to recover its economic strength by 2028. Thus, the downward mobility rate of the middle-class will be effectively mitigated or reduced.
