在新时代体育产业发展进程中,我国体育产业结构性失衡问题显得尤为突出,而推进体育产业供给侧结构性改革对破解体育产业结构性失衡具有现实意义。采用供给经济学、产业经济学等相关理论,剖析我国体育产业结构性失衡的表现形式,解构我国体育产业结构性失衡的形成原因,探寻我国体育产业结构性失衡的供给侧破解路径。研究表明:1)我国体育产业结构性失衡表现在:体育产业的产值结构、就业结构、供给结构等方面。2)体育产业结构性失衡的形成原因有:经济体制决定体育产业结构、体育发展战略固化体育产业结构、大众需求结构钢化体育产业结构。3)体育产业结构性失衡的供给侧破解路径为:明晰政府与市场边界,发挥市场在体育资源配置中的决定性作用;完善体育产业结构政策,发挥体育产业在体育发展战略中的作用;推进体育供需平衡,发挥体育产业在促进体育消费中的作用。 相似文献

Place kicks in Rugby Union present valuable opportunities to score points outside the spatiotemporal dynamics of open play but are executed under varying performance constraints. We analysed effects of specific task constraints and relevant contextual factors on place kick performance in the 2015 Rugby Union World Cup. Data were collected from television broadcasts for each place kick. In addition to kick outcomes, contextual factors, including time of the kick in the match, score margin at the time of the kick, and outcome of the kicker’s previous kick, were recorded. Effects of spatial task constraints were analysed for each kick, using distance (m) and angle (°) of the kick to the goalposts. A binomial logistic regression model revealed that distance from, and angle to, the goalposts were significant predictors of place kick outcome. Furthermore, the success percentage of kickers who missed their previous kick was 7% lower than those who scored their previous kick. Place kick success percentage in the 10 minutes before half-time was 8% lower than the mean tournament success percentage, which was 75% (95% CI 71–78%). The highest kick success percentage was recorded when scores were level (83%; 95% CI 72–91%). Our data highlighted how subtle changes in task constraints and contextual factors can influence performance outcomes in elite performers in international competition. Fluctuations in place kick success suggested that individual constraints, such as thoughts, emotions and fatigue, induced during competition, could interact with perceptions to influence emergent performance behaviours. 相似文献

职业教育领域的供给侧结构性改革是针对职业教育发展过程中的制度、体系、结构、内涵、质量等问题,解决人才需求与职业教育供给之间的结构性矛盾,提高人才供给适应性,扩大有效供给,实现需求与供给的平衡。本文从梳理广州市产业结构、产业从业人员结构等发展脉络入手,从院校招生规模、专业结构、层次结构、职业教育体系等方面,分析产业发展与职业教育人才供给出现的结构性矛盾,并提出广州市职业教育供给侧结构性改革的路径。 相似文献

The purpose of the study was to investigate the effect of different kicking modality, i.e., erratic-dynamic target (EDT) versus static target (ST) on the performance of the roundhouse kick in two groups of taekwondo athletes of different skill level. Three-dimensional analysis and surface electromyography (SEMG) analysis were performed on 12 (Group A: six sub-elite, Group B: six elite) athletes to investigate muscle co-activation pattern under two conditions, i.e., EDT versus ST. In the results, the muscle recruitment ratio of the agonistic muscles was higher for Group A, whereas Group B had higher recruitment ratio for antagonist muscles. Overall, the co-activation index (CI) of hip joints appeared higher in the extensors for Group A, whereas higher CI was observed in flexor muscles for Group B with comparatively higher CI during EDT condition than ST condition. Higher value of CI was observed in flexor muscles of the knee joints among Group A during EDT conditions, in contrast, higher CI in the extensor muscles was observed among Group B during ST conditions. In conclusion, the study confirmed that erratic-dynamic movements of target could change the movement coordination pattern to maintain the joint stability of participants. 相似文献
