本文利用2001-2010年我国30个省(市)的面板数据,通过面板协整方法研究了东、中、西部地区经济增长、能源消耗强度对二氧化碳排放量影响程度的差异。结果表明,二氧化碳排放量对经济增长变化的敏感度区域性差异较小,东部略高于中、西部;对能源消耗强度变化的敏感度,东部地区显著高于中部,中部显著高于西部。因此,应基于各地区的特征制定侧重点不同的节能减排政策。
In this paper, the panel data of 30 provinces (cities) in China from 2001 to 2010 are used to study the differences in the extent of economic growth and energy consumption intensity of carbon dioxide emissions in the eastern, central and western regions through panel cointegration method. The results show that the sensitivities of carbon dioxide emissions to the change of economic growth are less regional differences, with the eastern part slightly higher than the middle and western parts. The sensitivity to the change of energy consumption intensity is significantly higher in the eastern part than in the central part and higher in the central part than in the western part. Therefore, we should formulate different policies focusing on energy conservation and emission reduction based on the characteristics of different regions.
