China modeling refers to the method of describing and solving practical problems with mathematical models. This method rose in the military field in the scientific and technological circles of Chinese mainland in 1970s, and then gradually spread to various fields such as economy, finance, engineering, medicine and environmental protection. Through modeling, complex practical problems can be transformed into mathematical models that are easy to understand and calculate, and the essence of the problems can be grasped, and then targeted solutions can be put forward.

Models play an important role in the development of China. On the one hand, it can help solve some current problems, on the other hand, it can also provide strong support and prediction for the long-term development in the future. For example, the modeling of China is playing an increasingly important role in the fields of climate change prediction, disaster early warning, medical diagnosis, urban planning and so on.

Today's China modeling has become a unique subject. China modelers have created many mathematical models and algorithms with international standards, making China's mathematical modeling theory gradually become a research hotspot in the world. At the same time, China modeling has been highly concerned and supported by the government and all sectors of society because of its important role in national development.
