考虑政府干预与信息共享的装配式建筑供应链数字化转型决策研究

Research on Digital Transformation Decisions of Prefabricated Building Supply Chain Considering Government Intervention and Information Sharing

摘要: 为适应建筑业绿色发展和可持续发展的新要求，装配式建筑作为一种高效率、低污染的施工方式逐渐推广。伴随新一代数字技术融入装配式建筑生产过程，供应链迫切需要数字化转型以提升整体效率。本文构建了一个包含预制构件生产商和施工总承包方的供应链系统，研究企业在数字化转型过程中的最优决策，并进一步考虑政府干预和信息共享情景，比较分析不同机制对供应链数字化协同水平及成员收益的影响。研究结果表明，政府动态奖惩机制和信息共享机制均能有效激励预制构件生产商和施工总承包方提高数字化投入努力，但是政府激励成果与动态奖惩下限设定密切相关，存在“激励–挤出”效应。本文对装配式建筑供应链成员进行数字化转型和政府制定合理的激励政策具有一定的参考意义。

Abstract: To meet the new requirements of green development and sustainability in the construction industry, prefabricated construction has been increasingly promoted as an efficient and low-pollution construction mode. Meanwhile, with the integration of next-generation digital technologies into the prefabricated building production process, the supply chain urgently needs digital transformation to improve overall efficiency. This paper constructs a two-tier supply chain consisting of a prefabricated component manufacturer and a general contractor, and investigates firms’ optimal decision-making during the process of digital transformation. Furthermore, government intervention and information-sharing scenarios are incorporated to comparatively analyze the impacts of different mechanisms on the level of digital collaboration within the supply chain and the profits of its members. The results indicate that both the government’s dynamic reward and punishment mechanism and the information sharing mechanism can effectively incentivize the prefabricated component manufacturer and the general contractors to increase their digital investment efforts. However, the effectiveness of government incentives is highly sensitive to the lower bound of the dynamic reward–penalty scheme, and an “incentive - crowding-out” effect may arise under certain conditions. The findings provide managerial insights for the digital transformation of prefabricated building supply chain members and for the government to formulate reasonable incentive policies.
