体育彩票业网络关注度时空分异与影响因素研究

The Spatial-Temporal Differentiation and Influencing Factors of sports lottery Network Attention

网络关注度体现了人们对某种事物的现实关注和潜在需求,为研究大数据背景下事物发展趋势提供了新的数据参考。运用指数测度、探索性空间数据分析(ESDA)和地理探测器等方法,对2011—2021年我国31个省(市、自治区)体育彩票网络关注度的时空分异特征及影响因素进行分析。结果表明:(1)在时间上,2011—2021年中国体育彩票总体呈现先上升再下降并趋于稳定的态势。(2)在空间上,中国体育彩票网络关注度总体表现为集聚—随机—再集聚分布的特征;各省份之间空间异质性与空间依赖性并存;网络关注度的冷热点区域沿“胡焕庸线”两侧分布,呈现出南多北少、东部密集西部稀疏的极化效应。(3)地区生产总值、中青年人口数量、大专及大专以上人口数、互联网宽带接入用户数和体育彩票销量是造成中国体育彩票网络关注度空间分异的核心影响因素,各个因素的影响程度在地理空间上存在一定差异。

Network attention reflects people’s real concern and potential demand for something,and provides new data reference for studying the development trend of things under the background of big data.This paper used the methods of index measurement,exploratory spatial data analysis(ESDA)and geographical detectors to analyze the spatio-temporal characteristics and influencing factors of sports lottery network attention in 31 provinces(cities and autonomous regions)of China from 2011 to 2021.The results show that:(1)in terms of time,the overall trend of China’s sports lottery from 2011 to 2021 is to rise first,then decline and tend to be stable;(2)in terms of space,the overall focus of China’s sports lottery network is characterized by a cluster random cluster distribution;Spatial heterogeneity and spatial dependence coexist among provinces;The cold and hot spots are distributed along both sides of the“Hu Huanyong Line”,showing a polarization effect of more in the south and less in the north,dense in the east and sparse in the west;(3)The core influencing factors that cause the spatial differentiation of China’s sports lottery network attention nationwide are the gross regional product,the number of young and middle-aged people,the number of college students and above,the number of Internet broadband access users and the sales of sports lottery tickets.At the same time,the impact of each factor varies in geographical space.
