我国体育产业发展与国民经济增长关系的实证研究     

李国  孙庆祝 《武汉体育学院学报》2019,53(1):43

运用文献资料、数理统计、VAR模型等方法，基于2005-2015年国民经济与体育产业发展统计指标数据，通过协整检验、向量误差模型、格兰杰因果检验、脉冲响应函数与方差分解等，对我国体育产业发展与国民经济增长之间的关系进行实证分析。研究结果为：（1）协整检验与向量误差模型分析显示，体育产业增加值与国民经济发展之间存在正相关长期协整关系，这种均衡关系具有反向修正机制，当均衡关系发生波动时，当期以-1.744 073倍的力度对前一期偏离状态进行调整，将其拉回到长期均衡状态；（2）格兰杰因果检验显示，体育产业发展是国民经济增长的Granger原因，但国民经济增长不是体育产业发展的Granger原因；（3）脉冲响应函数显示，国民经济波动对其自身发展与体育产业发展均产生负效应，体育产业对于自身冲击的脉冲响应呈正相关趋势，并且能够迅速促进国民经济发展。（4）方差分解显示，国民经济在其自身发展与体育产业发展中的作用呈逐渐增大之势，体育产业的影响则呈逐渐减小之势。最后，提出了"识别均衡关系：促进国民经济与体育产业互惠共生发展"、"衡量脉冲响应：降低国民经济与体育产业均衡发展负效应"、"重视方差分解：权衡国民经济与体育产业影响因素相对性"、"完善政策法规：优化国民经济与体育产业均衡发展制度环境"等促进国民经济与体育产业均衡发展的现实路径。  相似文献

Moral Education of Youths in the Information Age     

Leslie N.K. Lo Fang Wang 《美中教育评论》2006,3(3):1-8

In Chinese societies, moral education has always been considered the most essential component of education because the nurturing of moral persons is the prime function of schooling. The implementation of moral education has relied on the inculcation of values that reflect moral ideals. The emergence of the Information Age, with a plethora of information and ideas being disseminated instantly through informational technologies, has altered the educational landscape of the world and challenged the conventional approach to moral education. Given this context, we argue that it is important for Chinese educators to find an alternative approach to moral education that can embrace the new realities of our networked world. In this approach, lofty moral ideals should give way to simple and easily understood concepts such as respect, information and ideas in the ＂cyber world＂ should be exploited rather than shunned, and the genuine interests of children and youths should form the basis of moral education that is at once relevant and enlightening. In proposing this approach to moral education, we also assume that moral educators in Chinese societies, which include school teachers, parents, and organizers of nonformal education programs, would endeavor to understand the complex world of cyber realities and devise feasible ways to suit contextual educational needs.  相似文献   

启发式教学对学生思维的启迪作用     

李国郴 《长江工程职业技术学院学报》1991,(2)

我今年50岁了,可说是年过半百。但一回忆学生时代的“寒窗”生活,课堂上老师教课的生动情景,有如电影一样在脑海中一幕幕闪过,尽管这些都是30年前的事了,也不无回味。 记得那是1958年的一天,我们在上解析几何二次抛物线方程问题,老师一上讲堂,就提出了一个使学生陷入深思的问题:用一根1长的方形条木作一矩形窗框,为了增加透光量和通风量,问如何做才能使窗子具有最大面积?如果作成下面为矩形、上边为拱形的窗框,如何做才能有最大面积?这是一个二次抛物线求极值的问题,现在看来十分简单,但那时对我这  相似文献   

Relationship between hyperuricemia and metabolic syndrome   总被引：6，自引：0，他引：6

Objective: To investigate the relationship between metabolic syndrome and hyperuricemia. Methods: A total of 2 374 subjects who received health examination in our hospital from Jan. 2004 to Dec. 2006 were enrolled in our study. Hyperuricemia is defined as ≥7 mg/dl (in men) or ≥6.0 mg/dl (in women). Metabolic syndrome was defined using AHA/NHLBI (American Heart Association/National Heart, Lung, and Blood Institute) criteria. Results: (1) The overall prevalence of hyperuricemia was 13.10%. The condition was more common in men than in women (19.07% vs 3.42%). (2) Among men, uric acid concentration is statistically significantly positively correlated with waist circumference, blood pressure, and triglyceride. Uric acid is negatively correlated with serum high-density lipoprotein-cholesterol (HDL-C). Uric acid concentration is most strongly correlated with serum triglyceride (r=0.379) and waist circumference (r=0.297). Among women, statistically significant positive correlations were noted for the serum uric acid concentrations with waist circumference, triglyceride and fasting plasma glucose. Serum triglyceride (r=0.329) and waist circumference (r=0.234) are most strongly correlated with uric acid concentrations. (3) Men with hyperuricemia had a 1.634-fold increased risk of metabolic syndrome as compared with those without hyperuricemia odds ratio (OR)=1.634, P=0.000. Women with hyperuricemia had a 1.626-fold increased risk of metabolic syndrome (OR=1.626, P=0.000) as compared with those without hyperuricemia. Conclusion: Hyperuricemia is prevalent among Chinese population. Additionally, serum uric acid is positively associated with metabolic syndrome.  相似文献
