【摘要】 为推动全民健身公共服务高质量发展，马拉松赛事作为典型的全民健身赛事活动，探究其空间分布规律及影响因素具有重要意义。为此，本研究以2023年马拉松赛事举办的相关数据为对象，综合运用地理集中指数、基尼系数与最优参数地理探测器等研究方法，探讨我国马拉松赛事的空间格局及其影响因素。研究发现：(1)我国马拉松赛事空间分布整体呈非均衡特征，其中C类赛事集聚程度最高，A类、B类次之，整体赛事整合后不均衡性有所缓解；(2)不同等级赛事驱动机制存在异质性，C类赛事主要依赖人口基数、道路长度与绿地面积等本地化基础资源；A类、B类赛事则以第三产业发展水平、道路长度与客运量规模等经济与交通枢纽要素为核心驱动力；3类整体赛事的驱动重心则向第三产业、绿地面积与体育设施等要素整合演进；(3)交互探测揭示多数驱动因子间存在双因子增强或非线性增强效应，表明赛事发展依赖多维度因素的协同。基于此，建议从优化区域布局、分类精准施策、强化基础设施等方面推动协同治理，促进我国马拉松赛事的空间均衡与高质量发展，从而构建更高水平的全民健身公共服务体系。更多还原

【Abstract】 To promote the high-quality development of national fitness public services,it is of great significance to explore the spatial distribution laws and influencing factors of marathon events,as a typical form of national fitness events. For this purpose,taking the relevant data of marathon events held in 2023 as the research object,this paper adopts research methods such as the geographic concentration index,Gini coefficient and optimal parameter geographical detector to discuss the spatial pattern of marathons in China and its influencing factors. The research findings are as follows:(ⅰ)The spatial distribution of marathons in China is generally unbalanced,among which Category C events have the highest agglomeration degree,followed by Category A and B events,and the imbalance of the integrated events is alleviated to a certain extent;(ⅱ)There are heterogeneous driving mechanisms for events of different grades. Category C events mainly rely on localized basic resources such as population base,road length and green space area;Category A and B events take economic and transportation hub factors such as the development level of the tertiary industry,road length and passenger traffic volume as the core driving forces;the driving focus of the integrated Category A,B and C events evolves towards the integration of factors such as the tertiary industry,green space area and sports facilities;(ⅲ)Interactive detection reveals that there are twofactor enhancement or nonlinear enhancement effects among most driving factors,indicating that the development of marathon events depends on the coordination of multi-dimensional factors. Based on the above findings,it is suggested to promote collaborative governance from the aspects of optimizing regional layout,implementing precise policies by category and strengthening infrastructure,so as to advance the spatial balance and high-quality development of marathons in China and further construct a higher-level national fitness public service system.更多还原
