基于DPSIR和改进TOPSIS模型的装配式建筑碳排放影响因素研究

Research on Influencing Factors of Carbon Emission of Prefabricated Buildings Based on DPSIR and Improved TOPSIS Model

“双碳”目标下装配式建筑在节能减排方面具有显著优势,探究其碳排放影响因素具有重要意义。通过文献分析法对装配式建筑碳排放影响因素进行筛选,基于DPSIR模型从驱动力、压力、状态、影响、响应5个层面构建装配式建筑碳排放影响因素指标体系,利用改进的TOPSIS模型对吉林省2010-2020年装配式建筑碳排放影响因素进行了实证研究。结果表明,5个层面对装配式建筑碳排放的影响程度不同,其影响程度排序为:压力>状态>驱动力>影响>响应。并根据分析结果针对性地提出顶层设计促进装配式建筑发展、优化装配式建筑用能结构、助推装配式建筑绿色发展的建议。

Under the goal of "double carbon",it is important to investigate the influencing factors of carbon emissions.Prefabricated buildings have significant advantages in energy saving and emission reduction. In this paper,we screened the factors influencing carbon emissions of prefabricated buildings through literature analysis. An index system of carbon emission influencing factors of prefabricated buildings is constructed based on the DPSIR model from five levels:driving force,pressure,state,impact,and response. An empirical study is conducted to analyze the carbon emission influencing factors of prefabricated buildings in Jilin Province from 2010 to 2020 using the improved TOPSIS model. The results show that the five levels have different degrees of influence on the carbon emissions of prefabricated buildings. Specifically, the influence degrees are ranked as:pressure > state >driver > influence > response. Finally,based on the results,the top-level design to promote the development of prefabricated buildings,optimize the energy use structure of prefabricated buildings,and promote the green development of prefabricated buildings is targeted.
