蘇花高的興建源起係於一九九○年由李登輝前總統所提出之「產業東移」政策,工商業界倡議興建蘇花高速公路,該項政策歷經了幾次的總統大選、縣市長及立法委員選舉,乃至於地方選舉,此項政策都僅止於規劃和環境評估之階段。本文採用Sabatier和Jenkins-Smith的倡導聯盟架構之理論,係因其兼顧理論的廣度與深度,深度係指政策次級系統概念之提出,廣度則涉及政策變遷過程當中,行動者的信仰系統與價值觀點的變項,該架構適足以檢驗蘇花高這項政策議題之演變過程。本文所欲探討的命題如下:第一,透過學者專家介入所產生之政策導向學習,經過社會輿論的發酵,對於政策目標之達成並無有效助益。第二,在贊成與反對聯盟激烈競逐之情勢下,政策掮客的出現並無助於政策議題之解決。第三,政策菁英之規範性深層核心信仰並不會因為重大事件之影響而改變,但其政策信仰則有可能因而改弦更張。
Based on the policy context of Su Hwa Highway in Hualien County, this article explores three propositions by applying the Advocacy Coalition Framework. The first proposition is that the involvement of academics and experts, based on public opinion, is not beneficial to the achievement of policy goals. Secondly, the appearance of policy brokers is not helpful to the solution of public issues when different coalitions compete for diverse policy goals. Thirdly, pivotal events do not change the normative core beliefs of policy elites, whereas their policy belief might be influenced and changed. This research indicates that the first two propositions are not sustainable, while the third one is.
