Health is an essential requirement for the promotion of comprehensive human devel-opment.Entering the new era,with the continuous improvement of China's livelihood protec-tion and welfare system,the health level of the population has been improving,and the relation-ship between health and welfare has become more closer.At present,there is still a lack of con-sensus understanding of the concepts,measurements and trends in the development of popula-tion health and welfare.Based on the coordinated and coupled relationship between the two sys-tems of health and welfare,this study constructs the national health and welfare development in-dex through the CRITIC weighting method,and analyses the basic trend of the development of national health and welfare during the 20-year period from 2003 to 2021,and found that the av-erage annual growth rate was about 1.17%from 2003 to 2021,and the average annual growth rate increased to 3.33%from 2012 to 2021.The contribution of physical exercise to the im-provement of national health and welfare was calculated,and the total contribution was 3.79%,which was higher than the annual per capita household expenditure on health care(2.99%,19th)and health expenditure(2.52%,21st).The overall trend of the contribution of physical activity from 2003 to 2021 showed an increasing trend,with an average annual growth rate was about 1.18%.
