摘要
基于2011年中国国家发改委确定的34个低碳试点城市的截面数据,构建了城市碳排放—新型城镇化系统评价体系,通过主成分分析和熵指数计算得出城市低碳发展—新型城镇化系统的综合评价指数,并进行系统协调度和协调发展度模型研究。研究结果显示,低碳试点城市碳排放与新型城镇化耦合协调具有以下几个特征:第一,低碳试点城市碳排放—新型城镇化系统耦合协调度上总体水平不高;第二,城镇化过程中,人均CO2排放量、公共服务、基础设施建设和资源环境水平不同程度地对低碳城镇化产生影响;第三,系统的协调度和协调发展度上表现出较强的空间地域性;第四,系统的协调度与协调发展度总体来说有很强的正相关性;第五,系统在新型城镇化水平、协调度、协调发展度指标和区域经济发展水平存在很强的对应关系,而城市碳排放系统、协调度、协调发展度指标与区域经济的关系并不明显。
Based on the data of 34 low carbon pilot cities in China, this paper builds up City carbon emission-New pattern urbanization system evaluation models. Mathematical and statistical analysis software of Matlab7.0 and SPSS18.0 are applied to calculate the index weights through principal component analysis and entropy evaluation methods and then get the comprehensive evaluation index of City carbon emission-New pattern urbanization system of which coordination degree model and coordination development degree model are investigated. Research result reveals that there are 4 basic consequences :first,the overall level of the coupling coordination degree of City carbon emission-New pattern urbanization system is not high;second, the system shows strong relationship between coordination degree and coordination development degree on the geographical regional type; third, the coordination degree and coordination development degree in general have a strong positive correlation; finally, the corresponding relation between the comprehensive evaluation degree, coordination degree, coordination development degree and the regional economic development level is intensively strong, on the contrary the relation is not significantly obvious between the comprehensive evaluation degree, coordination degree, coordination development degree and the city carbon emission level.
