低碳城市 低碳发展 区域差异
低碳城市 低碳髮展 區域差異
저탄성시 저탄발전 구역차이
low carbon city; low carbon development; regional difference
利用《中国城市智慧低碳发展报告》中我国GDP前110强地级以上城市的低碳发展数据，运用加权变异系数法和Theil指数分解法分析了大样本城市低碳发展水平的空间分异，并运用多元线性逐步回归模型定量分析了各层次低碳发展综合水平的影响因素及其差异。结果表明：样本城市的整体低碳发展水平不高，高值城市以东部地区的轻工业城市或综合型城市为主，低值城市则以中、西部的资源型城市或重化工业城市为主；城市整体的低碳发展水平的空间差异较大，低值城市的空间差异最大、高值城市的空间差异最小、中值城市的空间差异居中；城市低碳发展的区域分异主要由层次间的差异引起；碳排放系数、能源效率、人均GDP是影响城市低碳发展的主要因素；城市整体和中、低值城市影响因素的显著性的排序结果为碳排放系数〉能源效率〉人均GDP，而高值城市的排序结果是能源效率〉碳排放系数〉人均GDP。提出：可参考“共同但有区别的责任”原则分解各城市的碳减排量，对各层次城市宜采取差别化的低碳发展政策。
利用《中國城市智慧低碳髮展報告》中我國GDP前110彊地級以上城市的低碳髮展數據，運用加權變異繫數法和Theil指數分解法分析瞭大樣本城市低碳髮展水平的空間分異，併運用多元線性逐步迴歸模型定量分析瞭各層次低碳髮展綜閤水平的影響因素及其差異。結果錶明：樣本城市的整體低碳髮展水平不高，高值城市以東部地區的輕工業城市或綜閤型城市為主，低值城市則以中、西部的資源型城市或重化工業城市為主；城市整體的低碳髮展水平的空間差異較大，低值城市的空間差異最大、高值城市的空間差異最小、中值城市的空間差異居中；城市低碳髮展的區域分異主要由層次間的差異引起；碳排放繫數、能源效率、人均GDP是影響城市低碳髮展的主要因素；城市整體和中、低值城市影響因素的顯著性的排序結果為碳排放繫數〉能源效率〉人均GDP，而高值城市的排序結果是能源效率〉碳排放繫數〉人均GDP。提齣：可參攷“共同但有區彆的責任”原則分解各城市的碳減排量，對各層次城市宜採取差彆化的低碳髮展政策。

Using the data of low carbon development of top 110 cities in GDP from＂Smart Low Carbon Development of Cities in China＂ ,this paper uses the method of weighted coefficient of variation and the first-order decomposition of Theil index to analyze the regional difference in low carbon development levels of large sample cities. Then it uses the multiple linear stepwise regressions to analyze quantitatively the influence fac- tors of different low carbon development levels and their regional difference. The conclusions are as follows：the whole low carbon development level is not high,and the cities with high value consist of light industry cities or comprehensive cities in eastern region,while the cities with low value are mainly resource-based or heavy industry cities in mid-west region;the whole difference is very large, and the regional difference of cities with low value is the biggest,and that of cities with high value is the least, and that of cities with medium ones is in the middle; the regional difference mostly results from the differences among stratifications;CO2 emission coefficient,energy efficiency and per capita GDP are the main influencing factors of low carbon development of city; the significance of influencing factor for whole, medium and low value cities in descending order are all CO2 emission coefficient〉energy efficiency〉per capita GDP,but for high value cities,it is energy efficiency〉CO2 emission coefficient〉per capita GDP. Therefore,government should refer to the principle of＂common but differentiated＂to distribute the reduction of carbon emission,and adopt the differentiated policies of low-carbon development for cities with high,medium and low value.
