The combination integration of urban development models (CUDM) emerges as pivotal in aligning economic development with achieving the “dual-carbon” goals. However, existing studies often overlook CUDM's potential for carbon emissions reduction. Multi-period DID models exhibit excellent performance in mitigating endogeneity and eliminating omitted variables. This study examines the impact of t...

In grey system theory, the performance of an established grey forecasting model largely depends on how efficiently the grey information can be measured from data. Most existing grey forecasting models use grey accumulating generators to obtain grey information. However, not all grey information helps improve the performance of grey forecasting models. Consequently, simple accumulation leads to ...

Accurate short-term prediction of bioenergy power generation structure can optimize the bioenergy structure and help achieve carbon neutrality. However, there are currently few related studies, and most of them present long-term predictions on the development potential of bioenergy, which cannot meet the modeling requirements of predicting structure. Hence, the Fractional-order-accumulation gre...

Strategic emerging marine industries have become a new economic growth pole, and countries worldwide seek to transform their land economy into a marine economy. Institutional supply is the primary way for governments worldwide to support the development of strategic emerging marine industries. To study the impact of market cultivation on the supply efficiency of China's marine strategic emergin...
