Does the integration of the digital economy and the real economy enhance urban green emission reduction efficiency? Evidence from China
As a new engine driving high-quality economic development, the integration of the digital economy (DE) and the real economy (RE) (IDERE) may become crucial in enhancing the efficiency of green emission reduction (EGER). Based on panel data from 279 cities in China spanning from 2011 to 2021, this study explores the impact of IDERE on EGER. The results indicate: (1) IDERE can significantly enhance EGER. (2) Heterogeneity analysis shows that IDERE has a more substantial promoting effect on EGER in eastern regions, intelligent city pilots, cities with strong intellectual property protection, and cities with high industrial agglomeration levels. Mechanism analysis reveals that IDERE primarily boosts EGER by fostering green technological innovation (GTI), promoting industrial structure upgrading (ISU), and reducing energy consumption intensity (ECI). (3) IDERE exhibits a positive spatial spillover effect on improving EGER, facilitating collaborative emission reduction among cities. These findings provide new insights into promoting IDERE development and enhancing EGER, as well as offering fresh perspectives for achieving dual carbon targets.

Sustainable Cities and Society (SCS) is an international journal that focuses on fundamental and applied research to promote environmentally sustainable and socially resilient cities. The journal welcomes cross-cutting, multi-disciplinary research in various areas, including:
1. Smart cities and resilient environments;
2. Alternative/clean energy sources, energy distribution, distributed energy generation, and energy demand reduction/management;
3. Monitoring and improving air quality in built environment and cities (e.g., healthy built environment and air quality management);
4. Energy efficient, low/zero carbon, and green buildings/communities;
5. Climate change mitigation and adaptation in urban environments;
6. Green infrastructure and BMPs;
7. Environmental Footprint accounting and management;
8. Urban agriculture and forestry;
9. ICT, smart grid and intelligent infrastructure;
10. Urban design/planning, regulations, legislation, certification, economics, and policy;
11. Social aspects, impacts and resiliency of cities;
12. Behavior monitoring, analysis and change within urban communities;
13. Health monitoring and improvement;
14. Nexus issues related to sustainable cities and societies;
15. Smart city governance;
16. Decision Support Systems for trade-off and uncertainty analysis for improved management of cities and society;
17. Big data, machine learning, and artificial intelligence applications and case studies;
18. Critical infrastructure protection, including security, privacy, forensics, and reliability issues of cyber-physical systems.
19. Water footprint reduction and urban water distribution, harvesting, treatment, reuse and management;
20. Waste reduction and recycling;
21. Wastewater collection, treatment and recycling;
22. Smart, clean and healthy transportation systems and infrastructure;
