The new quality productivity, which integrates the concepts of technological innovation, industrial upgrading, and green development, plays a pivotal role in achieving carbon emission reduction targets. Given that current research on relationship between productivity intensity remains limited, order to delve into impact intensity, its underlying mechanisms, as well heterogeneous performance across different regions city types, we select panel data from 251 Chinese cities spanning 2010 2021 conduct an empirical analysis using two-way fixed-effects model. findings reveal can significantly reduce intensity. Further demonstrates achieve by enhancing urban innovation levels government environmental regulations. Moreover, heterogeneity indicates that, compared with other regions, inhibitory effect is more pronounced western non-resource-based samples. This study not only enriches relevant theories emissions but also provides crucial basis for governments formulate targeted policies. Based this, this paper proposes investment areas related should be increased, upgrading promoted, regulations strengthened. Particular attention paid development give full play reduction.

To advance the global sustainable development agenda and uphold emission reduction commitments of Paris Agreement, this study is dedicated to exploring potential digital infrastructure construction in fostering carbon reductions. Drawing on panel data from 249 cities China spanning period 2010 2021, we empirically analyze impact, mechanisms, heterogeneous effects urban emissions using a two-way fixed-effect model. Furthermore, delve into carbon-reducing new-type construction. The research findings indicate that can significantly decrease emissions; it achieves by enhancing green innovation heightening public environmental awareness, thereby further reducing emissions. In city samples located western regions, with higher government fiscal expenditures better foundations for new energy utilization, promotional effect reductions more pronounced. Additionally, demonstrates significant emissions, where well developed, even evident. This deepens our understanding mechanisms through which digitization empowers regional variations involved, providing empirical evidence governments formulate differentiated policies future research, plan expand scope investigation countries regions globally; concurrently, will conduct an in-depth analysis long-term

Small- and medium-sized ports (SMSPs) face multifaceted challenges, including environmental pressures (pollution, resource depletion) as well socio-economic strains (community impacts, trade dynamics). Governance complexities, regulatory fragmentation, limited funding, stakeholder conflicts further exacerbate these challenges. This study identifies context-driven sustainability indicators for SMSPs proposes best practices to enhance their resilience. Four small/medium-sized in Crete, Greece—Souda (CHA), Heraklion (HER), Rethymnon (RET), Sitia (SIT)—were evaluated benchmark performance using tailored indicators. The primary objectives were the following: (a) identify relevant SMSPs, focusing on economic, environmental, social aspects, (b) propose enhancing ports, considering unique characteristics constraints. A combination of Best Worst Method (BWM) VlseKriterijumska Optimizacija I Kompromisno Resenje (VIKOR) analysis was employed. findings revealed that “environmental monitoring management” “security employment protection” are top priorities while “competitiveness” a crucial indicator small emphasizing need financial context global trade. These results offer strategic roadmap policymakers, guiding interventions aimed at improving resilience thereby supporting regional economies international networks.
