摘要

2020年新冠肺炎疫情的爆发，迅速引起了人们的关注。基于百度指数，采用空间自相关和变差函数分析我国居民对疫情关注度的时空演变特征和空间分异机理，运用地理探测器对其影响因素进行探究。结果表明：①2020年1月16日—2月26日，全国范围内疫情的网络关注度呈先升后降的“倒V型”演变趋势，武汉“封城日”是其重要的时间拐点。②新冠肺炎疫情网络关注度存在显著空间正相关性，高高和低低集聚的空间特征明显；局部冷热点分布呈现以“胡焕庸线”为界的空间分异格局。③东—西方向为疫情网络关注度在空间分异上的主要方向。④新闻媒体宣传力度、人口密度、疫情传播路径、实时疫情和地理区位共同影响着疫情网络关注度的时空演变格局。

Abstract

When the novel coronavirus pneumonia outbroke in 2020, this public health emergency has attracted people's attention rapidly. Based on real-time data of Baidu index, this paper analyzes the spatio-temporal evolution characteristics of people's attention degree since the outbreak of novel coronavirus pneumonia epidemic through the spatial autocorrelation model. Moreover, this paper investigates the evolution mechanism of its spatial differentiation using the spatial variation function, and selects the geographical detectors to explore its influencing factors. The results show that:1) In the eastern, central and western regions of China, as well as nationwide, the nationwide network attention degree of the novel coronavirus pneumonia epidemic showed an "inverted V-shaped" evolution trend from January 16th to February 26th, 2020. 2) The novel coronavirus pneumonia epidemic network attention degree has significant spatial positive correlation, and the spatial characteristics of high and low concentration were obvious. 3) The spatial difference of network attention degree of novel coronavirus pneumonia epidemic has continued to shrink, the spatial differentiation caused by structural factors has gradually increased, and the scope of spatial correlation has expanded. 4) The strength of news media propaganda, and geographical location all affected the spatio-temporal evolution of network attention degree of novel coronavirus pneumonia epidemic in China.
