Abstract
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.
