| Summary: | 本文取徑經濟學的公共財概念，試圖從此一角度出發探討頻譜管理從「稀有論」轉向「公有論」的論述正當性，並釐清管理模式與財貨特性之關連。根據研究結果，頻譜資源的原始狀態雖符合公共財定義，但並非任何人所有，其財貨特性會隨著科技發展和法律制度而變動，因此「頻譜公有」的論述並未獲得專家學者支持。
儘管如此，頻譜資源在運用上需避免使用者相互干擾，因此建立一套合理的使用秩序，方能促使資源發揮效用。針對提供商業服務之頻譜，本文建議主管機關在規劃與指配上應給予使用者更多彈性，以類似出租國有地的方式，視頻譜資源為獨立客體並制訂相關法律；其次為放寬技術與用途限制，並在釋出資源後開放頻譜二次交易，讓分配效率得以提升。
長期而言，無線通訊科技將不斷演化，當干擾問題可獲得妥善解決，為追求資源使用效率，本文建議管理模式應朝開放共享的方向邁進。簡言之，「頻譜管理」任務本身就是一種公共服務，政府責無旁貸，唯有充分掌握頻譜資源的供給與需求變化，施政方針才能充分反應使用者需求。
=== This research argues that the scarcity rationale could be replaced by public spectrum rationale. The research results show that although the nature of spectrum resource is public good by economic definition, it doesn’t mean the resources are owned by the public. Therefore, the ownership of resources should be clearly defined under the law to prevent users from interfering with each other.
For spectrum used in private sector, the allocative efficiency is important for some valuable blocks of spectrum such as 800MHz, 900MHz, 1800MHz, 2600MHz. To improve allocative efficiency, the research result suggest that the government could legislate specific laws on spectrum management, while allowing users to decide how they want to make use of the resources.
In the long run, wireless communication technology will keep developing. As long as signal interference can be controlled under specific conditions, spectrum sharing including common regime and license-exempt use should be adopted. A government plays the key role which not only provides management service but should also have a systematic plan for improving spectrum efficiency.
