【摘要】 目的：研究我国体育系统本科院校人员数及其占体育系统总人数比例的数学模型，旨在为体育事业发展提供科学的依据。方法：利用2013-2020年我国体育系统本科院校人员数以及其占体育系统总人数比例的数据，建立GM(1,1)模型，并对模型进行检验。结果表明：我国体育系统本科院校人员数GM(1,1)模型为：■,体育系统本科院校人员数占体育系统总人数比例的GM(1,1)模型为：■。检验结果显示模型拟合好，预测精度高。最后利用该模型预测2021-2024年的数据，其结果为：2021-2024年体育系统本科院校人员数分别为(6214,6365,6519,6677),呈现逐年递增的趋势。更多还原

【Abstract】 OBJECTIVE: This paper studies the mathematical model of the number of people in undergraduate colleges and universities for China and its proportion in the sports system, aimed to provide a scientific basis for the advancement of sports undertakings. METHOD: The numbers of people in undergraduate colleges and universities for China from 2013 to 2020 and its proportion in the sports system were used, and a GM(1,1) model was set up and tested. RESULTS: the GM(1,1) model of the number of people in undergraduate colleges and universities for China is ■, and the GM(1,1) model of its proportion in the sports system is ■. The test results showed a good model fit and a high prediction accuracy. Finally, the model was used to predict the data from 2021 to 2024. RESULT: The number of people in undergraduate colleges and universities for physical education and sports from 2021 to 2024 is 6214, 6365, 6519, and 6677 respectively, showing a y-o-y growth trend.更多还原
