重要的发电部门对泰国的二氧化碳排放有很大贡献。在这项研究中，根据2000年、2005年和2010年的投入产出表，汇总了19个相关部门，以调查电力部门和其他部门之间的行业间联系。应用能源乘数和二氧化碳乘数对2010年19个行业的直接和间接能源强度和二氧化碳强度进行了测算。结果表明，发电行业具有较高的前向联动效应和较低的后向联动效应。因此，发电部门作为其他行业的投入来源具有很大的影响力，但吸引其他行业产出的能力较低。2010年，发电行业是能源密集度和二氧化碳密集度最高的行业，分别为1770×107千卡和3521吨二氧化碳百万美元。此外，19个行业的总间接能源强度和总间接二氧化碳强度分别占总强度的53%和52%。因此，建筑、机械和其他制造业中巨大的间接能源强度和二氧化碳浓度在泰国工业中发挥着重要作用，不容忽视。为了促进发电和其他相关部门的节能减排，这项研究建议泰国政府应促进建筑的可持续设计，并改善输配电流程。此外，今后拟建的核电站还应进行环境影响评价。本文所使用的方法可以应用于其他行业，也可以为政府评估能源消耗和二氧化碳排放的相对经济贡献和环境影响提供指导。
ABSTRACTThe vital electricity generation sector contributes substantially to CO2 emission in Thailand. In this study 19 relevant sectors, based on input-output tables for the years of 2000, 2005 and 2010, have been aggregated to investigate inter-industry linkages among the power sector and other sectors. Also, the energy multiplier and CO2 multiplier are applied to estimate the direct and indirect energy intensity and CO2 intensity of 19 industries during 2010. Results show that the electricity generation sector has a high forward linkage effect and a relatively low backward linkage effect. Consequently, the electricity generation sector has a significant influence as an input source for other industries, but it has a low capacity for attracting other industries’ output. In 2010 the electricity generation sector was the highest energy intensive and CO2 intensive industry with 1,770 × 107 kcal million US$–1 and 3,521 ton CO2 million US$–1, respectively. Besides, total indirect energy intensity and total indirect CO2 intensity from the aggregated 19 sectors accounted for 53% and 52% of the total intensity, respectively. Accordingly, the huge indirect energy intensity and CO2 intensity in the construction, machinery, other manufacturing played significant role in Thai’s industry, and should not be overlooked. To promote energy conservation and emissions reduction by the electricity generation and other relevant sectors, this study suggests that the Thai government should promote sustainable design of buildings and improve the electricity transmission and distribution processes. Besides, the environmental impact assessment should be undertaken for proposed nuclear power plant construction in the future. The methodology used herein can be applied to other industries, and they can also provide a guide for governments to evaluate relative economic contribution and environmental impact on energy consumption and CO2 emission.
