This paper studies the trend and influencing factors of population change in central China from 2001 to 2020. At the same time, the population regression models of three provinces of Henan, Hubei,Hunan are constructed and analyzed by using the methods of linear regression and principal component analysis. The results show that the population in central China has a negative growth trend in recent years, and the per capita GDP, birth rate, mortality rate, urbanization rate and industrial structure upgrading index have a signifi-cant impact on the total population, among the per capita GDP and birth rate change in the same direction of the total population of cen-tral China. Finally, some suggestions are put forward, such as that the government should adopt an active birth policy to spread good birth idea so as to increase the birth rate of the population in central China accelerate the economic development of central China to in-crease the per capita GDP, etc., in the hope of alleviating the problem of negative population growth.
