Construction and Development of a Green, Low-Carbon Circular Economy System Driven by New Quality Productive Forces: Evidence from Qinghai Province

Building a green, low-carbon, and circular economy system is crucial for achieving ecological protection and high-quality economic development. Focusing on Qinghai Province, this study uses the regional “Four-Zones Strategy” as an entry point to explore the framework for constructing a system driven by new quality productive forces. Using a combined weighting method and a coupling coordination degree model, the study constructs an evaluation index system to empirically analyze the synergistic evolution of Qinghai's green, low-carbon, and circular subsystems from 2008 to 2022. The results show a steady improvement in the overall performance of the green, low-carbon, and circular economy system, with progressively enhanced coupling and coordination among its subsystems. Policy guidance and industrial integration have played key roles in this progress. Based on these findings, the paper proposes policy recommendations, including integrating green computing power with AI technologies, establishing regional public brands, and developing demonstration bases. These measures provide theoretical guidance and practical references for Qinghai's green transformation and the achievement of China's carbon peaking and carbon neutrality goals.
