本論文應運而生於當今全球對環境、社會與治理（ESG）和永續發展目標（SDGs）議題的日益升溫之際。著眼於全球環境管理技術領域的創新，並針對中國、日本、美國三大經濟體在環境技術創新及專利策略的表現，同時探討我國在此全球趨勢中的策略定位與創新潛力。目的在於揭示這些國家在全球環境治理領域的角色及策略，並評估我國在環境技術發展上的機遇與挑戰。
本研究選擇Espacenet資料庫作為主要的資訊來源，並借鑒OECD Environment Working Papers的檢索策略，聚焦於空氣、水、廢棄物處理等重要環境技術領域進行分析。透過對比分析法和卡方分析，評估不同技術領域的專利活動，以全面了解全球環境技術的創新及地理市場的趨勢。
研究發現，過去近四十年間，全球在環境技術領域的專利申請量顯著增長，特別是自2000年代初期起。此趨勢反映了國際社會對於環境問題的重視和對技術創新的積極追求。中國、日本和美國在環境管理技術領域展現出顯著的領導地位，其中又以中國的專利數量尤為突出，顯示其技術創新與市場需求的活躍。此外，我國在某些領域顯示出潛在的發展空間，透過加強投資和發展，有望在全球環境治理中發揮更積極的角色。

This thesis emerges amidst the global emphasis on Environmental, Social, and Governance (ESG) and Sustainable Development Goals (SDGs). It focuses on environmental management technology innovations, scrutinizing the efforts of China, Japan, the United States, and Taiwan's strategic role in this realm. The study aims to discern their contributions to global environmental governance and evaluate Taiwan's potential in technological advancements.
Utilizing the Espacenet database and a search strategy from OECD Environment Working Papers, the research concentrates on pivotal areas like air, water, and waste management technologies. Applying comparative and chi-square analyses, it gauges patent activities to unfold global environmental technology trends.
The findings reveal a marked increase in environmental technology patents over the past four decades, accelerating since the early 2000s. This surge underscores the international community's commitment to addressing environmental challenges and fostering innovation. Among the examined nations, China demonstrates a commanding presence in patent applications, signaling robust market demand and innovation. Concurrently, Taiwan exhibits emerging potential in specific sectors, indicating its growing relevance in global environmental discourse. The study underscores the urgency for Taiwan to escalate its involvement in environmental technology to align with global standards and contribute significantly to international environmental governance.
