“双碳”背景下装配式建筑成本控制分析

An Analysis of Cost Control of Prefabricated Construction in the Context of Dual Carbon Initiative

在“双碳”背景下对影响装配式建筑成本的因素进行分析,利用系统动力学原理和层次分析法构建仿真模型,得到了影响成本的关键因素。结果表明:在装配化率和政府补贴相对稳定状态下,碳交易价格的上升可以显著降低装配式建筑成本;当碳交易对成本的直接影响较小时,增加政府补贴可以有效控制建筑成本。同时,建筑工业化的快速发展和装配式建筑规模的扩大,也能显著降低装配式建筑的成本。

The factors affecting the cost of assembled buildings are analyzed under the background of“dual-carbon”initiative,and the simulation model is constructed by using the principle of system dynamics and hierarchical analysis to obtain the key factors affecting the cost.The results show that:under the relatively stable state of assembly rate and government subsidy,the increase of carbon trading price can significantly reduce the cost of assembled building;when the direct impact of carbon trading on the cost is small,the increase of government subsidy can effectively control the cost of building.At the same time,with the rapid development of construction industrialization and the expansion of assembly building scale can also significantly reduce the cost of assembly building.
