本研究比較台灣五個産業(石化、鋼鐵、積體電路、汽車、造船)的發展過程,著重點在於評估産業政策在這發展過程中所扮演的角色,以檢驗新古典以及修正學派的相關理論。而結果發現:1)一個經濟體在當時的各種條件雖會限制其所可能發展産業的範疇,限制産業政策所能選擇的範圍,2)但是這限定出來的範圍相當廣泛,以致於産業政策的協調作用、社會化投資風險、以及幫助決定發展策略的功能,有相當大的發揮空間;3)但這只是潛在的可能性而已,産業政策的設計以及執行必須合宜,這些潛在的功能才有可能實現,而這確實是不容易做到的組合,同時,4)各個産業的特性,配合上政策環境的各種主客觀條件,就可能會使得各個産業的産業政策的設計與執行上的適切性有所差異,因此進而導致這些産業在經濟表現上呈現差異。
This study compares the development pattern of five of Taiwan's industries, which have been targeted for promotion by the government. The sectors studied include petrochemicals, steel, integrated circuit, automobiles, and shipbuilding. The study compares differences in the external and internal conditions, and the policy measures taken by the government in each sector, and weights them against the differences in the sector's for the policy to be effective. It is found that 1) though various conditions limit the range of options or potential targets (industries) available to the government, the limiting effects are far from determinant; 2) and leave a lot of room for industrial policy to play a role; 3) however, only if policies are appropriately designed, schemes effectively enforced and policy measure properly carried out, then industrial policy could have its desired effects; 4) differences in the industry characteristics and in policy effectiveness were found to be responsible for differences in the economic performance of these five industries studied.
