体育服务综合体空间分布特征及形成因素

Spatial Distribution Characteristics and Forming Factors of Sports Service Complex

运用最邻近指数、地理集中指数、核密度估值和空间自相关等研究方法探究体育服务综合体的空间分布特征,再使用逐步回归分析法进一步探究体育服务综合体空间分布的主导因素。结果表明:(1)体育服务综合体最邻近指数为0.82,具有显著的非均衡性和空间聚集特征,呈现南多北少,向东集聚的空间格局,主要集聚分布于长三角城市群。(2)体育服务综合体的地理集中指数G>■,空间分布呈现非均衡状态。(3)体育服务综合体呈现两大高密度区域,其密度分布特点遵循“核心—边缘”理论,呈现以一个高密度地区为核心向四周递减的状态。长江三角城市群分布密度最高,其次是渤海城市群地区;(4)体育服务综合体的数量具有显著空间自相关,且各省区市的体育服务综合体数量较多或较少在空间上都更易聚集。(5)体育产业示范基地、人均地区生产总值、地区文化市场机构数量、地区民用飞机场数量与体育服务综合体的分布呈显著的正向关系,地区铁路营业里程与体育服务综合体的分布呈显著的负向关系。

The paper uses the nearest neighbor index,geographic concentration index,nuclear density estimation and spatial autocorrelation to explore the spatial distribution characteristics of the sports service complex,and then uses the stepwise regression analysis method to further explore the dominant factors of the spatial distribution of the sports service complex.The results show that:1)The nearest neighbor index of the sports service complex is 0.82,which has significant imbalance and spatial agglomeration characteristics.It presents a spatial pattern of“more in the south and less in the north,gathering in the east”,mainly concentrated in the urban agglomeration of Yangtze River Delta;2)The geographic concentration index of the sports service complex is G>■,and the spatial distribution presents an unbalanced state;3)The sports service complex presents two high-density areas,and its density distribution characteristics follow the“core-periphery”theory,with a high-density area as the core and decreasing to the surroundings.The distribution density of the urban agglomeration of the Yangtze River Delta is the highest,followed by the Bohai urban agglomeration area;4)The number of sports service complexes has significant spatial autocorrelation,and the number of sports service complexes in various provinces and cities is more or less likely to gather spatially;5)The distribution of sports service complexes has significant positive relationship with the sports industry demonstration base,per capita GDP,the number of regional cultural market institutions,the number of regional civil airports while the distribution of regional railway operating mileage and sports service complexes are negatively related.
