Liou Yao-hwa's view is that Taiwan's future development should have three urban concentrations at its core. "Northern Taiwan should have Taipei at its heart, and include Ilan, Keelung, Taipei County, Taoyuan, and Hsinchu. With a population of about 9.5 million, it would be on a par with Belgium. The five counties of Central Taiwan would have Taichung City as their center, being roughly comparable to Singapore.
劉曜華則指出，台灣應該以 3 大都會區為核心發展：「北台灣以台北為中心，包括宜蘭、基隆、台北、桃園與新竹，人口約 950 萬人，約等於比利時；中台灣 5 縣市以台中市為中心，約等於新加坡；南台灣包括嘉義、台南、高雄、屏東，人口約 700 萬人，略高於香港。」
