การวิเคราะห์ประสิทธิภาพด้านการผลิตและความได้เปรียบโดยเปรียบเทียบของโครงการกลไกการพัฒนาที่สะอาดด้านพลังงาน : กรณีกลุ่มพลังงานชีวมวล / ชีวกฤต ลาภบุญเรือง = An analysis of productive efficiency and comparative advantage on energy sector in clean development mechanism : a case of biomass energy / Cheewakrit Lapboonruang
This study examines productive efficiency and comparative advantage on energy sector in clean development mechanism of biomass energy project. The observations were collected for 20 biomass energy projects in 2007, and then examined by stochastic production frontier analysis in format of transcendental logarithmic function. Comparative advantage also calculated by social cost-benefit ratio method in order to compare with shadow exchange rate. Result indicates that "Khon Kaen Sugar Power Plant" is the most efficient project with 99.727 percent nevertheless "Malwa Industries, Ludhiana Small Scale Biomass Project" is the less efficient project with 50.850 percent. All of this average efficiency through period is 89.716 percent. The shadow exchange rates were calculated by country, 34.7926 in Thailand, 8.4857 in China and 45.4606 in India. Ratio between Shadow Exchange Rate and Social Cost-Benefit ratio show that all observations have comparative advantage. The ratio for Thailand, China and India are 0.8253, 0.7163 and 0.5782, respectively. Whereas projects without CERs exhibit higher SCB/SER values or lower advantage.
