Progress, Challenges, and Policy Insights for Collaborative Innovation Pilots on Pollution and Carbon Emission Reduction

• • The first batch comprises 64 pilot units (21 cities and 43 industrial parks), covering strategic regions including Beijing-Tianjin-Hebei, Yangtze River Economic Belt, Guangdong-Hong Kong-Macao Greater Bay Area, Yangtze River Delta, and Yellow River Basin, with all units having issued implementation plans. • • Pilot types span resource-based, industrial, comprehensive, and ecologically sound cities, and industrial parks covering steel, nonferrous metals, petrochemicals, automobiles, equipment manufacturing, and new energy sectors, ensuring broad sectoral representation. • • Identified challenges include fragmented interdepartmental collaboration, insufficient management system alignment, funding shortages for synergistic projects, and inadequate technological support, which impede scaling of successful practices. • • Recommendations for the second batch emphasize expanding pilot types to include provincial, municipal, county, township, watershed, and enterprise-level entities, with tailored focuses such as cross-regional collaboration mechanisms and product life-cycle synergy, to enhance replicability and institutionalization.
