7. Conclusions and Limitations
7.1. Conclusions
- The results show that GR has the most significant impact on CERI. The relevant government departments not only explicitly require low-carbon requirements through policies, legal norms, standards and other documents, but more importantly, they carry out strict supervision, punish construction contractors who do not meet low-carbon standards, and suspend production or even suspend business licenses for enterprises that seriously pollute the environment. Only by strictly implementing policies can relevant government departments contribute to achieving the goals of “carbon peaking” and “carbon neutrality”.
- PS, SN, PBC have a significant impact on CERI. In addition to issuing strict regulations and supervision, economic measures can be taken to enhance contractors’ awareness and autonomy in carbon reduction, such as tax incentives, financial subsidies and green construction certification. Contractors can learn advanced construction technologies from each other through organizing enterprise forums, international exchanges and cooperation, and improve their low-carbon awareness through communication. In addition to technical factors, contractors can also achieve innovation by reducing construction plans, construction concepts, management methods, and other aspects similar to recyclable waste.
- The government indirectly affects CERI by influencing SN and PBC. The government can entrust third parties and stakeholders to supervise contractors. The government’s incentive policies can also improve the ability and power of enterprises to innovate and reduce waste technology, increase the use of renewable resources, and reduce environmental pollution.
