| 中文摘要: |
| 建筑业是能源消耗和碳排放大户，其碳减排势在必行。本文在对国内 30个省域建筑业碳排放量核算的基础上，运用空间自相关模型对其时空特征进行刻画，进一步采用 LMDI方法对建筑业碳排放进行因素分解。研究结果表明:建筑业碳排放总体呈现上升趋势，具有空间正相关性及空间集聚特征；省域建筑业碳排放整体呈现增长态势，存在空间差异且日益显著。全国建筑业碳排放的影响因素促进性因素依次是人口规模、产出规模，抑制性因素依次为能源排放强度、能源强度和建材排放强度；不同因素的影响效应存在地区差异，建材排放强度效应对华中地区的抑制作用最明显，产出规模效应对华中、华东地区有明显的促进作用；不同省域对中国建筑业碳排放的增加贡献存在差异，福建、江苏、安徽等省份贡献最大，新疆、青海、海南、内蒙古等省份贡献最小。 |
| 英文摘要: |
| The construction industry is a big carbon emitter in China，and its carbon emission reduction is imperative. This paper accounts for carbon emissions from the construction industry in 30 provinces in China，and uses a spatial autocorrelation model to portray and analyze its spatial and temporal characteristics，and adopts the additive logarithmic mean Dependent exponential decomposition(LMDI)method to factorize them. The research results show that:carbon emissions from construction industries show an overall upward trend，with positive spatial correlation in most years，and exhibit spatial clustering characteristics；China′s 30 provinces show an overall increase in carbon emissions from construction industries，but the spatial differences are getting more apparent； Population scale effect and output scale effect，in turn，promote carbon emissions in the Chinese construction industry；energy emission intensity effect，energy intensity effect，and building materials emission intensity effect， in turn，inhibit carbon emissions in the Chinese construction industry. There are regional differences in the effectsof different factors. The emission intensity effect of building materials has an obvious inhibitory effect on CentralChina，and the output scale effect has an obvious promoting effect on central China and East China. Different provinces have different contributions to the increase of carbon emissions in China′s construction industry. Fujian， Jiangsu，Anhui and other provinces contribute the most，while Xinjiang，Qinghai，Hainan and Inner Mongolia contribute the least. |
