基于城镇化视角的收入不平等对CO<sub>2</sub>排放的影响研究

摘要基于2001—2016年我国省市面板数据,运用STIRPAT模型探讨了城镇化进程中人均收入与CO₂排放之间的关系。研究表明:城镇化与我国CO₂排放存在负相关,CO₂排放随着人均收入的增加而增加。通过对各省份以收入不同水平进行分组研究,发现人均收入、城镇化水平与CO₂排放的弹性系数显示出很大差异。高收入组中,城镇化与CO₂排放存在正相关,而较低收入组中,城镇化与CO₂排放存在负相关。在较低收入组中,人均收入对CO₂排放的弹性系数要远远高于全国平均水平,弹性系数高达1.7298。因此,在较低收入群体中,随着人均收入的提高,将带来更多的CO₂排放。减少地区CO₂排放不仅需要缩小收入差距,还需合理布局城镇化发展,倡导低碳生活。

关键词：收入不平等 CO₂排放城镇化 STIRPAT模型

Abstract： Global energy and climate problem are arising when economic development is continuing. At present, relative studies about emission amount of CO₂ have been hot issues in Economics, Management, Geography and so on. The relationship of per capita income and emission amount of CO₂ during urbanization is studied through STIRPAT model with panel data based on 2001-2016 in this paper. As studies have shown that urbanization has negative effect on emission amount of CO₂ and per capita income has positive correlation to it. It is found that elastic coefficients of per capita and urbanization to emission amount of CO₂ have big differences through STIRPAT model with different groups of income among provinces. Urbanization has positive correlation to emission amount CO₂ within group of higher per capita income, but negative correlation within group of lower per capita income. Elastic coefficient of per capita income to emission amount of CO₂ belonging to lower group of income is 1.7298 which is higher than the average level of the whole country. It shows increasing income for lower level group of income will lead to more emission amount of CO₂. In order to decrease emission amount of CO₂, deducing gap in personal income, reasonable urbanization layout are necessary and low carbon life is also advocated.
