城市以集群的形式参与竞争已逐渐成为一种主流，城市集群而形成的城市群碳竞争力也将成为城市碳竞争力的集中展示。运用主成分分析法对珠三角城市群、京津唐城市群、武汉城市圈和呼包鄂城市群等4个城市群2007—2011年的碳竞争力进行实证分析，发现呼包鄂城市群碳竞争力最强、武汉城市圈最弱，城市群的碳竞争力并不存在东中西部城市群依次变强或变弱的分布特点，各城市群在发展碳竞争力上各有优劣势。就此对我国城市群碳竞争力的提升提出可行性建议。

It has become a mainstream that cities have gradually participated in competition in the form of clusters,and city group carbon competitiveness will demonstrate that of the city itself. In this study,principal component analysis is ap-plied to analyze the carbon competitiveness from 2007 to 201 1 of the following four city groups,namely,the Pearl River Delta City Group,Beijing ! Tianjin ! Tangshan City Group,Wuhan City Circle and Hu-Bao-E City Group. Here are the main findings:Among the four city groups,Hu -Bao -E City Group has the most highest carbon competitiveness, while Wuhan City Circle is the weakest,which is not subject to the distribution characteristics that the competitiveness of city group gradually becomes stronger or weaker from east to west. Instead,each of them has its own advantages and disad-vantages in the development of carbon competitiveness. In this sense,this paper aims to propose feasible suggestions to en-hance the carbon competitiveness of city groups in our country.
