摘要

Amid rapid digital technology advancement, the construction industry urgently requires digital transformation to achieve carnitially, carbon trading mechanismsbon reduction goals, yet faces critical challenges, including the absence of multi-agent collaborative mechanisms, limitations of traditional static models, and singular policy tools during the materialization stage. This study develops a tripartite evolutionary game model involving owners, building material suppliers, and construction enterprises to systematically reveal dynamic evolution patterns of digital carbon reduction under government intervention. Results demonstrate a three-stage progressive trajectory: initially, carbon trading mechanisms and fiscal subsidies cultivate building material suppliers’ digital capabilities. Subsequently, synchronized enhancement of owner regulatory subsidies requires governmental incentives exceeding 60 Yuan per square meter or supplier-generated emission reduction profits surpassing 40 Yuan per square meter to activate oversight, alongside optimized carbon prices ranging between 10 and 15 Yuan per 10,000 kg and guaranteed profit allocation exceeding 30% to construction enterprises to drive digital collaboration transformation. Ultimately, the sustainable digital collaboration ecosystem of carbon reduction autonomously emerges with mature supply chain digitalization. Decision-making mechanisms confirm that owner supervision responds to governmental incentives and emission reduction benefits simultaneously, construction enterprises demand profit allocation beyond critical thresholds, coupled with cost-covering carbon prices for collaboration, while building material suppliers’ digitalization primarily relies on owner subsidies and system synergy. The established dynamic analytical framework delivers theoretical foundations and practical guidance for phased digital decarbonization in construction.
