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.

近年來，隨著能源價格不斷飆漲以及溫室氣體大量排放造成的氣候異常變化，引起世界各國對於提高能源使用效率與加強溫室氣體排放管制的重視。溫室氣體大多由化石燃料燃燒所產生。因此，一般被視為能耗較高的發電、鋼鐵、水泥以及石化等產業，遂成為眾所矚目而被要求加強溫室氣體排放管制的主要產業。未來的產業發展規劃，必需兼顧經濟與環保，否則必將被世界潮流所淹沒。 因應全球溫室氣體排放管制趨勢，就台灣經濟發展面、財政建設面、環境永續經營面等層面考量分析，現階段石化產業之發展應對產業競爭力及環境保護做更多且更審慎的考量。於產業競爭力部分，建議中油開放民營，並運用部份釋股取得的資金，一方面引進先進的製程技術及進行設備更新，提升企業競爭力；另一方面整合國內仰賴台灣中油公司供料且在各產品領域擁有數十年營運經驗的中下游業者，建構泛中油體系的石化經營團隊。如此泛中油體系與國內另一石化產品鏈已相當完整的台塑體系，形成兩大石化體系，互為良性競爭。於環境保護方面，則建議我國應終止國光石化投資案，降低溫室氣體排放量，並藉提升廠商製程效率減少能耗，如此將使經濟發展及環境保護得以兼顧，亦達成原興建國光計畫之目的。 而未來台灣石化產業發展策略，技術發展需長期向下扎根，產品則朝高值化、精緻化發展，開發低能耗、低污染之替代能源，提升產品的附加價值，並將大宗石化耗能的產品移往海外能源低廉的地區，持續提升產業競爭力，並達成溫室氣體減少排放為目標。如是，台灣在環境保護日益重視之趨勢下，石化產業也得以永續發展。 / The high energy cost and the unusual climate change due to increasing green house gases（GHG）emission in recent years have attracted the global attentions and called for improvement of energy utilization efficiency and enhancement of GHG emission control. GHG are mostly produced by the combustion of fossil fuels. And the higher energy consumption industries such as power generation, steel, cement and petrochemical industries are thus strongly requested to reduce GHG emission. Economic development and environmental protection both are needed to be equally evaluated in the planning of future industry development. Taking petrochemical industry as an example, many of its mid-stream and down-stream products have become an unseparable part and of our daily life. In Taiwan, it has been over half century since the establishment of petrochemical industry, and now become top 10 petrochemical production countries in the world. The production value of petrochemical-related industries are very close to 4 trillion NT dollars, about 30% of total production value of domestic manufacturing sectors. Petrochemical industry and electronic industry are the two strong arms in supporting national economic growth. As a very important industry in Taiwan, however, the intensity of its GHG emission is only next to steel industry. The significant technology improvement in petrochemical industry has been achieved since the installation of the existing refinery, naphtha crackers and many petrochemical mid-stream production plants in Taiwan. It is well recognized that the GHG emission will be greatly reduced if the advanced technologies are introduced and the old facilities are revamped. Therefore, the writer would like to address a different approach toward KuoKuang Petrochemical Project which the government is giving an impetus to its execution. Here the writer would propose Taiwan CPC company, the state-owned petroleum company and the leader of Kuokuang Petrochemical Project, to become privatized after asset re-evaluation and collect some government capital from privatization through issuance of part of its shares to the open market. The capital thus collected can be used for enterprise reform. The important items of the enterprise reform include but not limited to introduction of the advanced technologies, revamping of existing facilities and establishment of a new well-integrated petrochemical conglomerate through mutual investment between Taiwan CPC and the mid-stream companies that rely raw material supplies from Taiwan CPC. From viewpoints of both economy and environment, government policy of implementation of KuoKuang Petrochemical Project is worthy for reconsideration. Formation of a CPC-lead petrochemical conglomerate would also benefit the current petrochemical companies that rely on raw material supplies from Taiwan CPC as their operation efficiencies would improved from business intergration. The newly formed conglomerate would be more powerful in further business development and more competitive in world market. They would have more resources to explore their potential in advanced technology development, in new business fields such as biomass energy, solar energy and so on. The CPC-lead petrochemical conglomerate would be able to enchance its competitiveness to another domestic petrochemical giant, Taiwan Formosa Group, and other petrochemical giants in the global market.
