摘要: | 本研究以某火力發電廠為研究對象,統計空氣污染防制設備之操作維護費、淨投資利息及折舊等,計算得該電廠五年(1998-2002年)平均空氣污染防制總成本為292百萬元。另外,本研究利用階層隨機取樣方式,分別抽取基隆七個行政區共500位市民進行空氣污染改善願付價值之問卷調查,經統計迴歸推估結果為每位基隆市民每年願意支付528元,以改善空氣品質。又以本問卷所得之空氣品質改善願付價值先經物價調整後,再作空氣污染社會成本效益移轉,計算空氣污染社會成本為PM10每公噸社會成本為11,265元,NOX每公噸社會成本為17,611元、而SOX為112,118元,甲電廠空污防治效益五年(1998-2002年)平均為774百萬元。最後利用成本效益分析方法計算得本個案電廠五年(1998-2002年)平均空氣污染防制效益成本比為2.65。 Taking a thermal power plant as the object of this study , its expenses on the maintenance of air-pollution protection facility and other costs such as net investment interest and depreciation are analyzed, the average annual cost of air-pollution protection was found to be NT 292 million dollars in the last five years (1998-2002). In addition , the Stratified random sampling was introduced to inquire 500 citizens of 7 districs in Keelung for conducting the questionnaire of “willing to pay price on air-quality improvement”; through the statistics regression analysis, it came to conclusion that each citizen was willing to bear his share of NT 528 dollars for “air-quality improvement”. Meanwhile , “the willing to pay price” was adjusted by introducing CPI ( commodity prices index ) and benefit transferring , the air pollution society cost of PM10 turned out to be NT 11,265 dollars per ton , NOx NT 17,611 dollars per ton , and SOx NT 112,118 dollars per ton. The average air-pollution protection benefit of this thermal power plant was NT 774 millions dollars in the last five years (1998~2002). Finally , by benefit-cost analysis, the average benefit-cost ratio of air-pollution protection in the last five years (1998~2002) was found to be 2.65. |
