本研究以交易成本理論（Transaction Cost Theory）為基礎，探討影響能源 需求者對於能源服務公司（Energy Service Company, ESCO）能源管理服務之 需求意願，並透過正式化控制機制連結能源服務公司內／外部情境構面。本 研究以臺灣上市上櫃的工業為研究對象，採取問卷發放、專家意見訪談兩 階段調查。研究結果發現：(1 ）能源服務公司的資產專屬性、能源管理服務契 約的複雜程度會與能源需求者的交易成本呈顯著正相關﹔（2）能源管理服務 的市場競爭程度、體制環境支持度會與能源需求者的交易成本呈顯著負相 關。本文總結，能源服務公司透過正式化控制機制的建立能提升能源需求 者的需求並加速產業開發，最後對能源管理服務之效率提出建言。

This paper aims to explore the intention of energy service demanders to the demands in energy management services by Energy Service Company (ESCO), combined with the internal control mechanisms and the external environments of ESCOs from the perspective of transaction cost theory. A general survey was conducted from the public firms in Taiwanese manufactures and several in-depth expert interviews. The results reveal that asset propriety and contract complexity are positively related to transaction costs. And market competitiveness and institutional supports are negatively related to transaction costs. This study further verifies the importance of formal control mechanisms, which are not only to strengthen market position, accelerate industrial development and solve transaction problem, but also to increase the demand intention of energy management.
