| Summary: | 碩士 === 佛光大學 === 應用經濟學系 === 106 === This study uses dynamic DEA models to assess energy efficiency takes 20 countries of the Asia-Pacific Economic Cooperation from 2010 to 2014. We select the capital stock, labor and fossil fuel energy consumption are input variables, carbon dioxide CO2 emissions are undesirable output, and the gross domestic product is the intertemporal conversion variable. It is also intended to produce, and the APEC economies are divided into annual energy and overall energy efficiency, and the improvement direction is proposed for the difference variables. With the proposal of magnitude, we will discuss the changes of inter-temporal conversion variables and propose suggestions for improvement. Finally, it analyses the implications of energy investment and efficiency policies of APEC economies.
The results show that Australia, Brunei, New Zealand and the United States are the best performers among APEC economies in terms overall energy efficiency from 2010 to 2014. A benchmark can be set base on the excellent energy efficiency during the study period.
The countries with lowest overall energy efficiency are Indonesia, Mexico and China,. There is great potential for improvement. Reducing capital stock, labor, fossil fuel energy consumption, carbon dioxide CO2 emissions, and increasing gross domestic product can increase energy efficiency, but countries do not want to reduce the state's capital stock, and labor and population birth adjustments are not easy. It can only start from adjusting the fossil fuel energy consumption, carbon dioxide CO2 emissions and domestic production gross. The results of the study show that in order to improve energy efficiency and reduce fossil fuel consumption and CO2 emissions, it is also expected to increase the gross domestic product, unless the countries can cut the policy from the policy and technical aspects, and appropriately adjust the energy policy and actively develop new energy technologies to effectively reduce carbon dioxide CO2 emissions and achieve optimal energy efficiency.
