【摘要】：研究建筑业物化能的影响因素对促进建筑业可持续性具有重要意义.为较为准确地研究建筑业物化能的影响因素,在构建部门拆分的投入产出生命周期评价模型的基础上,结合完全分解方法构建了完全结构分解模型.该模型将建筑业物化能影响因素分为列昂惕夫效应、强度效应和终端需求规模效应.采用该模型对2005—2010年建筑业物化能增长进行了实证研究.结果表明:1基于部门拆分的投入产出生命周期评价模型可在一定程度上减小产业部门划分粗略和统计数据不可靠等因素导致的误差,提高结果可靠性.22005—2010年建筑业物化能(以标准煤计,下同)增长了6.755×108t,终端需求规模效应显著拉动了建筑业物化能的增长,其贡献率高达188%;列昂惕夫效应也在一定程度上拉动了物化能增长,其贡献率为42%;强度效应则较为显著地发挥了削减物化能的作用,贡献率为-130%.3相比传统模型,完全结构分解模型消除了分解残差(-7.399×108t),从而提高了分析可靠性.从提高工程建设规划水平,加强基础设施和建筑维护,推进新型建筑工业化、绿色建造和智慧建造,促进建材生产过程节能减排和发展高性能建材等方面提出了控制建筑业物化能的建议.
[Abstract]:Study on the influencing factors of construction industry embodied energy is important to promote sustainable construction. The factors which effect the accurate study of the construction industry can be materialized, based on input-output life cycle assessment of construction sector split model, combined with the complete decomposition method to construct the complete structure decomposition model. The model of construction industry embodied energy factors into Leon Leontief effect, intensity effect and scale effect. The terminal demand growth model makes an empirical study of 2005 - 2010 the construction industry can be materialized. The results showed that: 1 error evaluation input-output life cycle model division can be reduced to some extent. The industrial sector leads to roughly and unreliable statistics based on factors such as, improve the reliability of.22005 2010 construction of energy (standard coal, the same below) increased 6.755 * 108t, the terminal needs. Effect of significantly boosting the construction industry of energy growth, the contribution rate of up to 188%; Leon Leontief effect to a certain extent, stimulating the embodied energy growth, its contribution rate is 42%; the strength effect is obvious to play a role to cut material, the contribution rate of -130%.3 compared to traditional model, complete structure decomposition model eliminates the decomposition of residual (-7.399 * 108t), so as to improve the reliability analysis. From the improvement of construction planning level, strengthen the maintenance of infrastructure and construction, promoting new industrialization of construction, green construction and the wisdom of the construction control for construction, put forward the suggestion of promoting the building of energy production process and energy saving and emission reduction the development of high performance building materials and so on.
