Analysis of physical activity in China Based on Linear Regression Model

By using the method of linear regression. Based on the data from CGSS in 2015, this article discusses the differences in the harms and systems of subjective class recognition and the influence of social and economic development on sports activities. The results show that:(1) Class identification and SES status have an impact on physical activity. Among them, there is a social division phenomenon in physical activity. (2) The influence of SES status on physical activity is greater than the influence of class identity. All this shows that people in higher strata positions will use their own advantages to consolidate their social status. It shows that subjective class recognition cannot surpass the social development of participating in sports activities. Therefore, this discussion believes that the key point of improving the amount of group exercise may be to complete the fairness and justice of sports culture. Actually, we must do the following aspects: (1) Increase the attention and frequency of social development and exercise, vigorously promote social productivity, and respond to the “right theory”; Small “structuralism”;(3) To truly achieve equality, it is necessary to strengthen the core concept of public cultural services of the local government and improve the socialist social laws and regulations to reduce the “harmfulness of subject and object theory to sports activities.”
