摘要:	近年來有關環境保護與資源再生的相關議題逐漸受到大眾重視，為了兼顧經濟發展與生態保護，政府不但在桃園、台南、高雄及花蓮設置環保園區，並且積極推動資源再利用、再生能源等相關環保產業。本文所探討電弧爐煉鋼集塵灰是屬於有害事業廢棄物之一，其富含鋅、鐵、鉛及鉻等有價金屬。因此，各國競相投入研發電弧爐煉鋼集塵灰回收再利用技術，不僅減少有害物質危害環境，並使有限的資源能永續循環使用。為了探討有害事業廢棄物集塵灰資源再利用及汙染物排放量關係，此研究資料採A公司財務報表、生產報表和申報汙染排放等相關數據，引用KLEM投入產出模型，並以OLS做統計迴歸分析。結果顯示：（1）產品與電力費用及投入原料集塵灰有顯著正向關係。（2）汙染物排放量與有害廢棄物處理量及主要物料使用量有顯著正向關係。We human beings pay more and more attention on environment protection and resource reuse recent years. For business development and ecological protection, Taiwan government not only established environment protection areas in Taoyuan, Tainan, Kaohsiung and Hualien, but also support the related business such as resource recycling, renewable energy…etc.This study discusses the about electric arc furnace steelmaking dust, one of hazardous industrial waste, riches in divalent metals such as zinc, iron, lead and chromium. Thus, lots of nations devote to the related research and develop their technique of electric arc furnace steelmaking dust recycling. It decreases the influence on the environment of those hazardous materials, and such limited resources can be reuse.To investigate the relationship between the recycling of harmful industrial waste and emissions of pollutants, the research materials used in this article is from A Company’s financial statement, production report, and pollution emissions data. By using the KLEM I-O model, regression analysis and industrial competition analysis, our results show: (1) There is a significant positive relationship between products and electricity costs and investment in the raw flue dust, (2) Pollutant emissions have significant positive relationship with the amount of hazardous waste treatment and material use.
