本文主要的目的在於針對中國發電產業的發展現況進行探討,並運用產業經濟學中Mason-Bain的「結構-行為-績效」理論,分析其市場結構、廠商行為與營運績效。並採最大五大廠商集中率(Five-firm concentration ratio, CR5)作為衡量市場集中度之指標,以探討中國發電產業的市場結構。在廠商行為部份以訂價行為、研究與創新、設廠投資、 產品開發策略與廣告及法律行為探討該產業之廠商行為及競爭策略。另以財務觀點常用的績效指標衡量業者的績效表現。 依據SCP模式的理論基礎,從市場集中度,產品差異化和進入退出壁壘等方面分析了中國發電產業的市場結構,以調整市場結構開始,來提高發電產業的市場績效,並 提供可以借鑑的理論基礎和政策建議。最後根據研究結果,研擬出五大發電集團之因應發展策略,並提出具體建議,供國內相關業者或政府經營決策之參考,藉以提升中國發電產業之競爭優勢。;The main purpose of this paper is to discuss the status of the development of the power generation industry in China and to analyze the market structure, firm conduct and operating performance by using the Mason-Bain′s "structure - conduct - performance" theory in the industrial economics. The study used Five-firm concentration ratio(CR5) as the index to measure market concentration. The price behavior, research and innovation, etc., are used to investigate the organization behavior and the strategy. The performance indicator from the financial point of view is used for evaluating the performance of the Power generation industry in China. This paper analyzes the market structure of the power generation industry in China based on the SCP model from the market concentration, product differentiation and entry and exit barriers, etc., in order to provide the theoretical basis and policy recommendations for increasing the market performance of power generation industry by starting from the adjustment of market structure. Finally, according to research result, the paper draws up the development strategy of Top5 Power Generation Groups in China, and provides concrete suggestions for domestic related operators or the government to make management decisions, and finally to promote the competitive advantages of the power generation industry in China.
