利用中国30个省会城市1999～2008年相关数据研究了人口密度、发展水平等因素对城市人均碳排放量的影响。回归结果显示,人口密度与城市人均碳排放呈＂U＂型关系,收入水平与城市人均碳排放表现出倒＂U＂型的环境库兹涅茨曲线特征。进一步的分组回归结果表明,不同地域城市的密度效应、发展水平与碳排放呈不同模式特征,北方城市人口密度提升更有利于降低城市碳排放,东部城市发展水平与人均碳排放的倒＂U＂型特征已经显现,而中西部仅表现出线性关系,其中,上海、杭州等东部城市已达到或接近人均碳排放峰值,而中西部城市离总体回归估计的排放峰值收入水平尚有一段距离。

This paper analyzes the impacts of population density and income level on carbon dioxide emission of cities based on the data of 30 provincial cities ranging from 1999 -2008. The regression results from the whole sam- pie reveals that population density shows U shape relationship with urban carbon dioxide emission per capita, and income level takes on invert U shape relationship like EKC pattern with urban carbon dioxide emission. Regression results by group show that cities in different regions have various modes as far as the relation between population density, development level and carbon emission. The increase of population density in Nothern cities would signifi- cantly lower urban carbon emission ; the development level of east cities have taken on invert U shape relations with carbon emission per capita while that of middle - west cities have only linear correlation with carbon emission per capita. Specifically, east cities such as Shanghai, Hangzhou etc have approached the peak of carbon emission per capita, while the middle - west cities are still far away from the peak level of carbon emission per capita.
