中文摘要
      以2005—2016年中国30个省的建筑业数据为依据,识别出主要的二氧化碳(CO2)排放源,将其作为投入指标重新构建了评价中国建筑业全要素碳生产率(CI TFCP)的指标体系.然后采用数据包络分析和基于生产前沿的收敛检验方法研究了2005—2016年各省的CI TFCP指数及其收敛性.得到以下结论:中国及其东、中、西部地区的CI TFCP均逐年升高,东、中、西地区的年均升高率由高到低;材料和能源消耗强度、科技、教育和能源结构等均可能影响CI TFCP指数;中国及其东、中、西部各省与最佳生产前沿省份的平均差距,最佳生产前沿与最差生产前沿省份的差距均逐年扩大.基于以上结论,提出了降低材料消耗强度、引导研发投入和促进技术扩散等提高中国CI TFCP的建议.
英文摘要
      Based on the construction industry data of 30 provinces in China from 2005 to 2016, the main carbon dioxide (CO2) emission sources were identified and used as input indicators to reconstruct the evaluation indicator system of the construction industry total factor carbon productivity (CI-TFCP). The data envelopment analysis method and convergence test method based on production frontier were used to study the CI-TFCP index and its convergence of the provinces from 2005 to 2016. The conclusions are as follows: CI-TFCP in China and its eastern, central and western regions all increase year by year, with the highest average annual growth rate in the east and the lowest in the west. The intensity of materials and energy, technology, education, and energy structure may affect the CI-TFCP index. The average gap between China and its eastern, central and western provinces and the best production frontier provinces, and the gap between the best production frontier and the worst production frontier provinces have been expanding year by year. Based on the above conclusions, suggestions have been proposed for improving the CI-TFCP in China by reducing the intensity of materials, directing R&D investment, and promoting technology diffusion.
