It can be seen from the successful hosting of the 2008 Olympic Games and the upcoming Winter Olympics in China that my country’s sports economy is on the cusp of rapid development. However, my country’s backward physical education in colleges and universities seriously hinders the development of the sports economy. In order to adapt to the sports economy in my country’s new situation, the reform of college sports education is imminent. To this end, this article mainly injects capital into the reform of physical education in colleges and universities, strengthens teachers through economic strength and complements various competitions, so that my country’s sports economy is steadily on the road of rapid development. In this experiment, the sports economic profit of the experimental group that injected college physical education through the economy was as high as 1.7 million yuan, 8.5 times higher than the control group of traditional physical education. This also confirms that the development of the sports economy first needs to inject capital into sports education, so as to increase people’s consumption of sports activities through education, in order to promote the steady development of my country’s sports economy.
