Abstract: This paper uses Guangzhou Chimelong's network attention data of China's 31 provinces (cites) during 2015 to 2019 by using statistical and economically geographical methods and Baidu Index to study its temporal-spatial evolution based on five indicators, seasonal concentration index, variance coefficient, Herfinahl-Hirschman index, primacy index and geographical convergence index. The results show that China pays a rising network attention on Chimelong with a seasonal variance at seasonal concentration index being 1.991 1, 1.138 9, 1.954 3, 1.324 3 and 1.842 2 for the years 2012 to 2019. Provincial network attention has variance coefficient is 0.8, primacy index close to 3 with a higher convergence. Across the whole China, variance coefficients from the western, central, eastern is 0.349 3, 0.361 7, 0.332 8, 0.381 2 and 0.384 3, at a geographical convergence index above 60, implying a big but slowly rising difference. In the central and western, primacy index is 1, Herfinahl-Hirschman index is near to 0, and geographical convergence index lies between 31 to 38, meaning a balanced spatial structure, while in the eastern, the primacy index close to 3, geographical convergence index between 37 to 40, suggesting a higher convergence and a relatively-unbalanced spatial structure. Its temporal-spatial variance of network attention on Chimelong is a comprehensive aftermath of economy, population, network development and geographical distance with correlation coefficients at 0.693, 0.607 and 0.479 with the former three and -0.577 with the last one.

摘要： 运用统计学、经济地理学等跨学科理论方法，基于“百度指数”数据共享平台，选择广州长隆作为研究案例，收集2015—2019年中国31个省/市（港、澳、台除外）的广州长隆网络关注度数据，利用季节集中指数、变差系数、赫芬达尔指数、首位度指数和地理集中指数5个指标，分析广州长隆网络关注度的时空差异特征。研究结果表明：1）全国对广州长隆的网络关注度呈增长趋势，且存在季节性差异，2015—2019年的季节集中指数分别为1.991 1、1.138 9、1.954 3、1.324 3和1.842 2；2）各地区对广州长隆的网络关注度省际平均变差系数约为0.8，差异凸显，首位度指数接近3，集聚程度较高，关注度较为集中；3）2015—2019年全国对广州长隆的网络关注度的变差系数分别为0.349 3、0.361 7、0.332 8、0.381 2、0.384 3，地理集中指数在60以上，差异显著，且整体上差异缓慢增加，集聚程度在加强，其中中部和西部地区，首位度指数约为1，赫芬达尔指数接近0，地理集中指数在31～38，区域内空间结构相对均衡，但东部地区，首位度指数接近3，地理集中指数在37～40，区域内集聚程度较高，空间结构较为不均衡；4）广州长隆网络关注度时空差异是经济发展水平、地区人口规模、网络发达程度和地理空间距离等因素综合影响的结果，其中，与经济发展水平、地区人口规模、网络发达程度呈显著正相关，相关系数分别为0.693、0.607、0.479，与地理空间距离呈显著负相关，相关系数为-0.577。
