基于面板数据的我国碳排放区域差异研究

Study on Regional Differences of Carbon Emission in China Based on Panel Data

主要利用30个省市1997—2012年共16年间的面板数据,结合STIRPAT模型,考虑人口、人均GDP、能源强度、城镇化水平、工业结构和对外贸易程度等6种影响碳排放的因素,对我国东中西3个区域~1的碳排放差异进行比较分析。研究结果表明:东部区域对外贸易程度的提高是降低碳排放的主要因素,而城镇化水平则是影响碳排放增加的主要驱动因素;工业结构是影响中部区域的碳排放的主要因素;经济发展水平对于西部区域的碳排放影响作用最大。不同区域应当根据区域特点,制定符合区域特色的节能减排对策,实施区域差异化减排策略。

This paper uses the panel data of 30 provinces about 16 years during 1997-2012,combined with the STIRPAT model,to compare and analyze the regional difference factors of carbon emissions of Eastern,Central and Western China,including population,per capita GDP,energy intensity,urbanization level,industrial structure and foreign trade degree.The results show that the increase of foreign trade degree is the key reason to reduce the carbon emissions of Eastern China,while urbanization level is the main driving factor that affects the increase of carbon emissions;industrial structure is the main factor affecting the carbon emission in the central region;and economic development level has the greatest impact on the carbon emission in the western region.According toregional characteristics,different regions should implement the strategy of regional difference reduction,and take the road of energy saving and emission reduction with Chinese characteristics.
