Lu Bing-yan believes that both Kaohsiung and Hualien international harbors meet the conditions for establishing a free port zone, and other clear candidates should include the industrial ports of Mailiao in Yunlin County and Hoping in Hualien County, where in fact the local people have stated repeatedly that they will actively seek free port status.
針對自由貿易港設置地點，魯炳炎則認為，高雄、花蓮等國際港均是符合設置條件的港口，此外還應該納入雲林麥寮和花蓮和平兩個工業專用港，實際上地方人士也已經多次表態爭取。
