運輸建設可帶動區域發展,惟運輸建設亦同時改變各區域發展之核心、腹地(Core-Periphery)關係。行政院經建會(2002)研擬「挑戰2008國家發展重點計畫」,研議興建蘇花國道,藉以達成「平衡區域發展」與「觀光客倍增」等多重目標。本文主要沿用Liew與Liew(1985)多區域變動係數投入產出(MRVIO)模型爲分析工具,探討若蘇花國道通車後,針對花蓮地區可能產生之觀光效益進行評估。交通建設往往影響建設沿線人口與產業聚集,本文延續馮正民與林楨家(1992)之勞動市場整合模式,進一步預測花蓮地區之人口遷徙效果。研究發現觀光產業之效益,考慮人口增加與消費影響效果後,對花蓮本地之影響雖大,但大部分效果則外溢至台北、高雄等核心城市,北部區域反而產生強者恆強的磁吸效應,總效果以北部地區最大,花蓮次之。
Economic development process, many countries witnessed Urban- Rural problem. Because the constraint of geography factors, eastern Taiwan development pattern were different from western Taiwan. The Executive Yuan (2002) have planned to build Su-Hwa Highway, to achieve multiple goals of balance regional development, doubling tourist arrivals and Island-wide trunk transportation construction. Transportation is an key factor of regional development. This research try to apply Liew and Liew (1985) Multiregional Variable Input-Output Model, in order to assess economic,tourism and environment impact. This research found after Su-Hwa Highway Operation, because of the transaction cost saving effect, Hualien district will have the most toutism economic growth benefit.
