Research on Leading the Green Construction of Modern New Hunan with Prefabricated Buildings

在“双碳”目标与湖南省“三高四新”战略背景下，装配式建筑作为绿色建设的核心载体，对推动现代化新湖南发展具有重要意义。当前湖南省装配式建筑虽具试点先发优势，但面临配套产业失衡、建造成本高企、技术标准待完善等挑战。本研究基于政策驱动、技术适配与本土创新相统一的装配式建筑内涵，运用文献研究、实地调研与跨学科理论分析，解构绿色环保与经济效益失衡、产业链协同不足、政策市场双重约束等核心矛盾。从政策创新、技术突破、产业升级、成本优化四维度构建路径：政策层面完善“双碳 + 产业”协同治理，探索碳交易对接；技术层面研发本土化低碳技术与数字化管理平台；产业层面培育龙头企业与产业集群，拓展公共建筑应用场景；成本层面建立全生命周期评估模型，通过容积率奖励等机制激活市场。研究表明，需通过政策引导、技术创新、产业协同与市场驱动四维联动，突破“技术–经济–政策”壁垒，为新湖南绿色建设提供可操作路径，助力实现“双碳”目标与建筑产业现代化融合发展。Against the backdrop of the “double carbon” goals and Hunan Province’s “Three Highlands and Four New Missions” strategy, prefabricated buildings, as a core carrier of green construction, hold significant importance for promoting the development of a modern new Hunan. Although Hunan has a first-mover advantage in prefabricated building pilots, it faces challenges such as imbalanced supporting industries, high construction costs, and imperfect technical standards. This study, based on the connotation of Chinese modernized prefabricated buildings that integrate policy-driven, technology-adaptive, and locally innovative characteristics, employs literature research, field surveys, and interdisciplinary theoretical analysis to deconstruct core contradictions, including the imbalance between green sustainability and economic efficiency, inadequate industrial chain coordination, and dual constraints from policy and market forces. Four-dimensional paths are constructed: policy innovation to improve “double carbon + industry” collaborative governance and explore carbon trading integration; technological breakthroughs to develop localized low-carbon technologies and digital management platforms; industrial upgrading to cultivate leading enterprises and industrial clusters while expanding application scenarios in public buildings; and cost optimization to establish life-cycle assessment models and activate the market through mechanisms such as floor area ratio incentives. The study demonstrates that through the coordinated efforts of policy guidance, technological innovation, industrial collaboration, and market-driven forces, it is possible to break through “technology-economy-policy” barriers, providing an actionable path for Hunan’s green construction and facilitating the integrated development of “double carbon” goals and architectural industrial modernization.
