隨著第六代行動通訊技術（6G）逐步邁入標準制定與場域驗證階段，非地面網路（Non-Terrestrial Network, NTN）作為實現「全球覆蓋、韌性通訊」的關鍵架構，已正式被納入IMT-2030國際標準願景之中。鑒於我國地面網路高度密集、地理環境特殊且非ITU會員國，在推動6G NTN發展過程中，將面臨頻譜資源配置與制度設計等多重挑戰。本研究旨在探討我國發發展6G NTN優劣勢分析、對於頻譜管理之影響以及與現有頻段干擾之情境分析。
本研究採用文獻分析法，並輔以參與數位發展部於2023年舉辦之6G NTN座談資料作為次級補充資料（非主體訪談），彙整產官學界之既有觀點，進行交叉比對與歸納分析。首先，針對我國推動6G NTN之優劣勢進行探討，指出雖民間市場需求有限，但具備ICT產業供應鏈整合與高公共應變任務需求之潛力；其次，就NTN使用頻譜對我國現行頻譜管理制度造成之制度衝擊提出評估，強調我國應建立具彈性且兼顧公用性之頻譜政策體系；最後，針對通透型（transparent）與再生型（regenerative）系統在不同鏈路階段對IMT系統造成之干擾風險進行分類與情境分析，提出需建立共存規則與干擾評估模型之建議。
綜合分析結果指出，台灣雖在商業規模與國際制度參與方面尚存瓶頸，但於災防、戰備與偏鄉等公共性應用場域中，已具備推動6G NTN佈建之實質基礎。建議未來政策可聚焦於場域導向、公共任務優先與制度彈性原則，並強化跨部門協作與國際衛星服務合作，推動我國成為全球非地面網路技術供應鏈與應用的關鍵節點，以掌握6G時代通訊體系之新興戰略機會。

As sixth-generation (6G) mobile communication technologies advance toward global standardization, Non-Terrestrial Networks (NTN) have emerged as a critical enabler for achieving ubiquitous coverage and resilient connectivity. Taiwan, with its dense terrestrial networks, unique geographic vulnerabilities, and non-membership in the International Telecommunication Union (ITU), faces distinct challenges in developing NTN infrastructure. This study aims to evaluate Taiwan’s development prospects for 6G NTN from three perspectives: (1) national strengths and weaknesses, (2) impacts on existing spectrum management frameworks, and (3) interference risks associated with NTN system deployment.
This research adopts a document analysis approach and incorporates secondary data from the 2023 “6G Cross-Domain Applications and Spectrum Management” forum organized by the Ministry of Digital Affairs. The study synthesizes expert perspectives from government, industry, and academia to enrich its policy analysis. It highlights Taiwan’s potential in public service applications—such as disaster response, national defense, and rural coverage—while acknowledging limitations in market size and institutional engagement. Particular attention is given to spectrum conflicts in mid-band frequencies and interference risks arising from transparent and regenerative satellite system architectures.
The findings recommend scenario-driven policy design, flexible spectrum governance, and enhanced international collaboration to establish Taiwan as a strategic contributor in the global NTN ecosystem and strengthen its digital resilience in the 6G era.
