Moving Towards Synergistic Reductions on PM2.5 and CO2 and Its Mechanism: A Case Study of Yangtze River Economic Belt, China

CAS | Tsinghua University
Abstract
The Yangtze River Economic Belt (YREB) is a pivotal contributor to China’s economic growth, particularly as the nation undergoes a green transformation. Achieving synergistic reductions on pollution and carbon emissions is deemed crucial for this transition. This paper examines the spatial and temporal changes in the synergy of pollution and carbon reduction in the YREB and delves into the underlying mechanisms. Our findings indicate that while the synergy in the YREB is increasing, it manifests disparities across regions, with the lower reaches outperforming the middle and upper ones. Enterprise behavior, government guidance, and regional endowments influence this synergy. Cities in the YREB must strategically plan their urban scale, curb population overgrowth, recalibrate their industrial structures, curtail energy consumption, and enhance policy efficacy. Distinct regions should prioritize various objectives: the lower reaches should hasten scientific advancements and technological innovations; the middle reaches should foster innovation and industrial upgrades; and the upper reaches should prioritize rural and urban land intensification.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
