中国体育彩票业发展的空间关联网络结构特征研究

基于2002-2020年中国大陆31个省（区市）体育彩票业数据，借助修正引力模型构建体育彩票业发展的空间网络关系，运用社会网络分析方法（SNA）对我国省际体育彩票业发展的空间关联网络结构特征进行实证分析。研究发现：在样本考察期内，中国省际体育彩票业发展的空间关联关系数总体呈上升态势，省际体育彩票业发展的网络结构并非"等级森严"，但随时间的变迁其互动联系进一步增强。省际体育彩票业发展的空间关联网络结构中的连线增多，稳定性进一步增强。北京、天津、上海、江苏、浙江和福建对我国省际体育彩票业发展的空间关联及空间溢出效应具有较大影响力，在空间关联网络结构中处于比较中心位置，扮演着"中心行动者"的角色。在省际体育彩票业发展的空间关联网络结构中，第Ⅰ板块包括北京和天津两市，属"双向溢出"板块，第Ⅱ板块包括广东、上海等5个省市，属"主受益"板块，第Ⅲ板块包括吉林、内蒙古、河北等9个省（区市），属"主溢出"板块，第Ⅳ板块包括江西、湖北及广西等15个省份，属"经纪人"板块。各大板块间存在不同方向、不同路径的互动传导机制，在东西方向和南北方向上均存在比较显著的"梯度"溢出效应。

Research on Structure of Spatial Association Network of Sports Lottery Industry in China

Based on the sports lottery industry data of 31 provinces and municipalities in Chinese mainland from 2002 to 2020, this paper constructed the spatial network relationship of sports lottery industry development with the help of the modified gravity model, and used the social network analysis method (SNA) to analyze the spatial network structure characteristics of the development of sports lottery industry among provinces in China. The results showed that:(1) during the sample period, the number of spatial correlations of the development of China's provincial sports lottery industry was generally on the rise. The network structure of the development of China's provincial sports lottery industry was not "strictly hierarchical", but its interaction was strengthened with the change of time. There were more connections in the spatial correlation network structure of the development of provincial sports lottery industry and its stability was enhanced. Beijing, Tianjin, Shanghai, Jiangsu, Zhejiang and Fujian had a great influence on the spatial correlation and spatial spillover effect of the development of the provincial sports lottery industry in China. They were at a relatively central position in the spatial correlation network structure and played the role of "central actors". In the space of a provincial sports lottery development association network structure, Plate I included Beijing and Tianjin, belonging to a "two-way overflow" plate,. Plate II included Guangdong, Shanghai and three other provinces, belonging to the "main benefit" plate. Plate III included nine provinces, such as Jilin, Inner Mongolia, Hebei, belonging to the "overflow" plate. Plate IV included 15 provinces such as Jiangxi, Hubei and Guangxi, belonging to the "broker" plate. There were interaction conduction mechanisms of different directions and different paths among the plates, and there were significant "gradient" spillover effects in the east-west areas and the north-south areas.
