"双碳"目标下"无废城市"建设的技术路径与协同机制研究OACHSSCD

To address the systemic lock-in of"high-carbon and high-waste"in cities under the"dual carbon"goals,this study constructs an institutional-technical-behavioral analytical framework to explore the synergistic pathways for building"zero waste cities".The research identifies three key technological drivers:energy transition,decarbonization in key sectors,and digital intelligence enablement.It reveals a significant two-way feedback effect between the low-carbon transformation of urban energy systems and the closed-loop regeneration of material metabolism.The study argues that establishing a synergistic carbon-waste governance framework is essential,requiring the integration of extended producer responsibility with carbon market mechanisms.By developing a dynamic emission factor database,implicit emission reduction benefits can be transformed into carbon assets.Furthermore,a performance evaluation system based on material flow analysis should be established to promote cross-departmental collaboration.To tackle challenges such as policy misalignment and technological marketization bottlenecks,the study recommends designing flexible accountability boundaries,fostering a"technology-industry-market"symbiotic ecosystem,and innovating green financial instruments to alleviate financing constraints.This provides a theoretical foundation and policy insights for achieving urban low-carbon and zero-waste transitions.
