Abstract：As the climate crisis intensifies, the Earth & Climate System Model as a key numerical simulation tool for predicting and responding to future climate change has become increasingly important. The Coupled Model Intercomparison Project (CMIP) aims to promote model development and deepen scientific understanding of the Earth’s climate system, and has become a core platform for international model exchange and application. This paper summarizes China’s participation in the sixth CMIP (CMIP6), and statistically analyzes the citation situation, research overview and characteristics of Chinese models in CMIP6-related studies. The results show that Chinese models are widely used and have a far-reaching impact, but lack highly cited achievements. It is necessary to integrate resources and focus on developing representative models. In addition, this paper briefly introduces the seventh Coupled Model Intercomparison Project (CMIP7) under preparation, and summarizes the opportunities and challenges China faces in model development. The application prospects of Chinese models are broad, but there is still room for improvement. China should continue to increase investment in research and development, maintain international competitiveness, and be well-prepared for continued in-depth participation in global climate change governance.
