摘要:	循環經濟受到重視，愈來愈多企業朝向循環經濟以減少資源消耗、提高企業獲利，降低環境污染。化工業是製造業的基礎，卻面臨資源稀缺、嚴重浪費和環境問題，其生命週期的每個階段皆可能對環境產生負面影響；故許多化工企業發展循環經濟以改善上述所提到的問題。本研究擬評估2014至2016年化工產業的循環經濟績效以檢視成效，採用跨期動態網路資料包絡分析法(Dynamic Network Data Envelopment Analysis)。此方法考慮跨期觀點，且能衡量多種投入與產出或具有未知生產函數的工業流程，同時考量到中間不良產出與鍊接活動。以全球化工企業作為研究對象，針對循環經濟的整體效率進行探討，分析化工企業的生產效率與循環效率，並觀察化工企業循環經濟的年度績效變化。研究結果顯示化工業的循環經濟成果才剛開始推展，大部分化工企業的生產效率十分成熟，在循環效率上則有改善空間。故鼓勵化工企業可以藉由本研究之管理決策矩陣與投影分析，找到提升循環經濟績效的方向，達到最有效率的表現。;With the high attention on the circular economy, more and more enterprises turn toward the circular economy to reduce resource scarcity, increase corporate profits, and decrease environmental pollution. The chemical industry is the foundation of the manufacturing industry, but it faces scarcity of resources, serious waste and environmental problems. Each stage of its life cycle may have a negative impact on the environment; therefore, many chemical companies develop circular economy to improve the above mentioned problems. This study aims to evaluate the circular economy performance of the chemical industry from 2014 to 2016 so as to examine the effect. This study uses the Dynamic Network Data Envelopment Analysis method because it considers periods .And it is able to evaluate multiple inputs, outputs even unknown industrial processes. while considering undesirable outputs and linking activities. Taking global chemical companies as research objects, this paper discusses the overall efficiency of circular economy, analyzes the production efficiency and environmental efficiency of chemical enterprises, and observes the annual performance changes of chemical enterprises′ circular economy. The research results show that the circular economy results of the chemical industry have just begun to be promoted. The production efficiency of most chemical companies is very mature, and there is room for improvement in environmental efficiency. Therefore, chemical companies are encouraged to use the management decision matrix and projection analysis of this research to find the direction to improve the performance of circular economy and achieve the most efficient performance.
