Carbon and nitrogen are central elements in global biogeochemical cycles. To effectively manage carbon China, we developed a comprehensive model for quantifying their fluxes, investigating interplay across 16 human natural subsystems. Between 1980 2020, losses China increased 2.3-fold emissions surged 6.5-fold. Integrated management holds the potential 74% reduction to air water 91% decrease atmosphere by 2060. Compared with separate control of or nitrogen, integrated delivers an additional 1.8 million tons 26.5 2060, bringing out 37% unit abatement cost net societal benefit 1384 billion USD.

This study focuses on the coupling and coordination between China’s new-type urbanization (NU) transportation carbon emission efficiency (CET), revealing its spatial temporal evolution patterns driving factors. In recent years, rapid rise of digital economy has profoundly reshaped traditional industrial structures. It catalyzed new forms production consumption opened up pathways for reduction. makes synergies NU CET increasingly important realizing a low-carbon transition. addition, infrastructures such as 5G networks big data platforms promote energy facilitate upgrading. also promotes integration goals into urban governance, thus strengthening linkages CET. The aims to provide scientific basis regional synergistic development green transformation goal “dual carbon”. Based panel 30 provinces in China from 2004 2021, adopts entropy weight method super-efficiency SBM model quantify CET, then analyzes their interactions spillovers by combining coupled degree Durbin model. following is found: (1) show pattern “leading east lagging west”, are optimized over time, but with significant differences; (2) jumps “basic disorder” coordination”, not yet reached level advanced coordination, clustering characteristics (Moran’s I index 0.244 0.461); (3) labor force structure, intensity, structure technological innovation core factors have spillover effects, while government intervention per capita income limited roles. paper innovatively reveals two-way mechanism breaks through unidirectional research framework, systematically feedback effect two. A multidimensional evaluation system constructed overcome limitations previous single economic or demographic dimension, comprehensively portray comprehensive urbanization. multi-dimensional measurement framework proposed law perspective spatio-temporal dynamics correlation. paths key finally quantified. findings decision-making references optimizing policies, promoting transportation, taking advantage economy.
