移动信息化时代居家网络依赖特征和影响因素研究——以南京市为例

THE FEATURES AND THE INFLUENCING FACTORS OF HOME NETWORKTHE NETWORK DEPENDENCE IN MOBILE INFORMATION AGE:DEPENDENCE AGE:A CASE STUDY OF NANJING

随着信息网络日新月异,ICT对家庭生活影响越来越大,而人们在家花在ICT时间比重也越来越高。本文针对居家网络活动,尝试提出居家网络依赖概念,以2012年南京市居民个人信息网络问卷调查为基础,构建指标体系,采用因子分析、聚类分析、回归分析等方法研究居民居家网络依赖程度的时空特征,属性特征及其影响因素。研究发现:居家网络依赖程度分为3种,不依赖,轻度依赖和重度依赖,网络活动集中在休息日的17点至23点;空间上呈现两中心向外围递减的圈层模式。居民的个人社会经济属性和职住属性对居民居家网络依赖程度产生显著的影响,年龄、信息设备水平、职住距离尤为显著。

The paper focuses on the activities which are done on the intemet at home and proposes the inter- net independence concept, which is based on the 2012 survey questionnaires about personal information us- age. The paper builds up the index system, uses the factor, cluster, regression to analyse the citizen home in- ternet dependence level on time-geography and attributes characteristic, influence factor. The result shows that the home independence degree/level could be divided into three parts： non-dependence, light-indepen- dence and heavy-dependence. From the perspective of time length about home internet dependence, the dif- ferences between residents＇ weekend activities at home are small. In addition people have plenty of time at home at weekends which is much more than that on weekdays. The internet activities at home at weekends concentrate from 17 to 23 o＇clock. Spatial pattern shows that the distance decreases from inner to outer city. Home internet dependence decreases from Caochang Gate and Gulou to Confucius temple and Huju road. With the method of variance test, different home internet dependence level has a significant difference in ed- ucational degree, information usage level, regional feature and internet activities, but not（no significant dif- ference） in sex and age. Besides, citizens＇ socioeconomic and attributes of home and workplace, spectially age, information equipment level and the commute distance also significantly affect the internet dependence.
