【摘要】：【目的】信息消费已成为日益增长的消费热点,为了促进城镇居民的信息消费水平,对其影响因素进行研究。【方法】分析中国城镇居民信息消费的发展状况及空间相关性,以及当期信息消费会受到的三种内、外部影响,构建相应的理论模型,进一步基于动态空间杜宾模型进行实证研究。【结果】当期信息消费支出对相邻地区并没有产生空间溢出效应,信息消费表现出耐用性特征,而居民信息消费会受相邻地区居民信息消费习惯的影响;影响因素中物价和收入的提升,短期内会促使本地居民信息消费支出增加;而受教育水平和信息基础设施水平的提升,短期内会对相邻地区产生显著的正向空间溢出效应;长期效应中,只有物价和收入对本地居民信息消费支出有影响。【局限】由于数据的可获得性,选用物价指数、受教育水平、信息基础设施、网民人数、收入等5个因素进行分析,未考虑的因素可能会对分析结果产生影响。【结论】在研究居民消费的影响因素时,必须考虑空间效应的各种影响,否则估计结果可能是有偏的。
[Abstract]:[objective] Information consumption has become a growing consumption hotspot. In order to promote the level of information consumption of urban residents, the influencing factors are studied. [methods] the development and spatial correlation of information consumption among urban residents in China are analyzed. As well as the three kinds of internal and external influences that information consumption will be subjected to in the current period, the corresponding theoretical model is constructed. Further empirical research based on the dynamic spatial Doberman model. [results] Information consumption expenditure in the current period has no spatial spillover effect on adjacent areas, information consumption shows durability characteristics, The residents' information consumption will be affected by the residents' information consumption habits in neighboring areas; the increase of prices and income among the influencing factors will prompt the local residents' information consumption expenditure to increase in the short term; and the education level and the information infrastructure level will be improved. In the short term, there will be significant positive spatial spillover effects on adjacent areas; in the long run, only prices and income will have an impact on the information consumption expenditure of local residents. [limitations] because of the availability of data, the price index is chosen. Five factors, such as education level, information infrastructure, number of Internet users and income, are analyzed. The unconsidered factors may have an impact on the analysis results. [conclusion] when studying the influencing factors of residents' consumption, The effects of spatial effects must be considered, otherwise the estimation results may be biased.
