京津冀城市群体育场馆时空特征及影响因素

Spatiotemporal Characteristics and Influencing Factors of Sports Venues in the Beijing-Tianjin-Hebei Urban Agglomeration

体育场馆建设是京津冀体育协同发展的重要内容和载体,也是推动区域经济社会发展、提升区域竞争力和吸引力的重要手段。将北京、天津及河北11个地级市现有体育场馆作为研究对象,采用2015年、2021年数据以建立体育场馆城市吸引力的引力模型。运用社会网络分析方法,从网络密度、节点中心性、凝聚子群等指标,对京津冀城市群体育场馆时空特征进行定量分析,得出:从时间演化的角度来看,京津冀整体网络空间布局呈现出以北京为中心的放射状向外辐射,张家口、唐山等城市与北京空间联系逐步加深;京津冀城市群体育场馆建设网络结构发生新变化,从以北京为核心的单中心模式转变为多中心、多层次的网络新格局;2015—2021年京津冀城市群中心城市由3个增加为6个,石家庄、唐山、保定在联动南部城市和东部城市中发挥着越来越重要的桥梁作用,张家口、承德组团发展,邢台、邯郸处于边缘地区;体育场馆的时空分布受政策、经济基础、人口状况、体育产业发展状况尤其大型赛事的影响。建议:做好政策牵引,加强交流与共享,促进体育场馆协同联动;促进经济增长,做优内容以提高场馆利用率,激发现存场馆活力;聚合优势,做强赛事,实现场馆协同生态发展。

The construction of sports venues is a vital content and carrier of the coordinated development in the Beijing-Tianjin-Hebei region,as well as an important means to promote regional economic and social development,enhance regional competitiveness and attractiveness.This article selected Beijing,Tianjin,and 11 prefecture-level cities in Hebei as research objects,and used the 2015 and 2021 data to establish an attractiveness model for sports venue cities.By using social network analysis methods,quantitative analysis was conducted on the spatiotemporal characteristics of sports venues in the Beijing-Tianjin-Hebei urban agglomeration based on indicators such as network density,node centrality,and cohesive subgroups.The results are revealed as follows:from the perspective of temporal evolution,the overall network spatial layout of the Beijing-Tianjin-Hebei region shows an outward radiation with Beijing at the centre,and the spatial connection between Beijing and cities such as Zhangjiakou and Tangshan are gradually tightened.The network structure of sports venues in the Beijing-Tianjin-Hebei urban agglomeration has undergone new changes,shifting from a single Beijing-center model to a new network pattern with multiple centers and levels.From 2015 to 2021,the number of central cities in the Beijing urban agglomeration increased from 3 to 6.Shijiazhuang,Tangshan,and Baoding played an increasingly important role as bridges between southern and eastern cities;Zhangjiakou and Chengde developed hand in hand;while Xingtai and Handan were gradually marginalized.The spatial and temporal distribution of sports venues is influenced by policies,economic foundations population and the development of the sports industry,especially large-scale events.Therefore,it is recommended to:do a good job in policy guidance,strengthen communication and sharing,and promote the venue coordination and connection;facilitate economic growth,optimize the contents to improve the availability of venues,and stimulate the vitality of existing venues;integrate the advantages and better develop sports events to achieve collaborative eco-development of venues.
