在全球氣候變遷與淨零碳排壓力日益加劇的情勢下，能源轉型已成為多數國家邁向永續發展的重要途徑，離岸風電因具備高穩定性與大規模發電潛力，已成為全球能源政策中的重要技術。台灣為達成2050年淨零目標，規劃於2030年達成13.1 GW離岸風電裝置容量，並於2046至2050年間提升至40至55 GW，其中浮動式離岸風電將扮演未來目標量的關鍵角色。本研究以台灣浮動式離岸風電為研究對象，透過投入產出分析(Input-Output Analysis)評估其對台灣經濟與產業結構的潛在貢獻。首先整理國內外浮動式離岸風電之技術現況與成本結構，建立符合台灣產業體系的投入產出模型。為預測裝置容量之發展趨勢，本研究透過S曲線設計高、中、低三種發展情境，並搭配學習曲線預測其成本下降趨勢。透過模擬結果，分析浮動式離岸風電對各產業帶來的經濟影響及其在不同發展情境下的減碳潛力，以綜合探討其經濟與環境效益。
研究結果顯示，浮動式離岸風電無論在建置或運維階段，皆具備顯著的經濟帶動潛力。建置階段的產值與所得貢獻高度集中於資本密集型產業，如：金屬製品、機械設備與營建工程。在產業快速擴展的高成長情境下，2040年總產值帶動高達1.97兆元，附加價值貢獻逾1兆元，創造逾47萬個工作機會，所得帶動高達4,000億元，展現在高投資期的潛在經濟效益。相較之下，運維階段雖年效益相對較小，但具長期穩定特性，對區域經濟與服務型產業結構具持續性貢獻。高成長情境下2050年可帶動達500億元的產值帶動，並創造1.4萬人就業與138億所得帶動。在環境效益方面，本研究顯示，隨著裝置容量與發電量成長，其減碳潛力亦同步提升，在高成長情境下2050年二氧化碳減量約1040.42萬噸，即使在低成長情境下減碳量亦達685.86萬噸。
最後，依據研究結果，建議政府未來在推動能源轉型政策時，同步落實產業在地化、技術能力提升與人才之培育等規劃，以確保產業發展的持續性與自主性。亦建議強化綠色金融，以促進整體產業對離岸風電等減碳項目的參與，加速低碳轉型進程。

In pursuit of net-zero carbon emissions by 2050, Taiwan has set ambitious targets to expand offshore wind power capacity to 13.1 GW by 2030 with further growth projected to reach 40 ~ 55 GW by 2050. Floating offshore wind generation technology is expected to play a pivotal role in attaining these goals. This study employed input-output analysis to assess the impact of offshore power generation on industrial development, carbon reduction, and key national economic indicators. Learning curves were used to predict trends in cost reduction, and the trajectory of installed capacity was simulated under three scenarios: high-growth, baseline-growth, and low-growth.
Our findings indicate that Floating offshore power generation will provide considerable economic and environmental benefits. During the construction phase, these projects could have substantial short-term economic benefits, particularly in capital-intensive industries. Under the high-growth scenario, it is estimated that by 2040, this sector could drive NT$1.97 trillion in output and support nearly 500,000 jobs. Despite a modest economic effects during the operations and maintenance (O&M) phase, these projects could make a sustained contribution to regional economies and service-oriented sectors. Under the high-growth scenario, O&M could generate NT$50 billion in output and generate roughly 14,000 jobs driving NT$13.8 billion in income.
Carbon reduction potential scales proportionally with installed capacity. By 2050, annual CO2 emissions could be reduced by 10.4 million tons under the high-growth scenario or 6.86 million tons under the low-growth scenario.
