| 摘 要： 采用2018年中国家庭追踪调查(CFPS)数据，基于因子分析法，从基础使用情况、使用范围及频率、使用深度与重要性三个层面测度样本家庭互联网使用水平；构建QUAIDS模型，探究互联网使用水平对居民家庭消费结构升级的影响。研究发现，互联网使用水平对家庭消费结构升级的影响包含促进效应和抑制效应：促进效应体现在属于必需品的食品边际消费有所下降，属于奢侈品的教育文娱、生活用品和杂项类边际消费有所增加，且家庭边际消费越高，互联网使用水平的促进效应越明显；抑制效应体现在属于必需品的衣着和交通通信边际消费有所增加，属于奢侈品的医疗保健和居住边际消费有所下降。这主要源于互联网在刺激了家庭消费需求和意愿的同时，节省了家庭的消费成本。通过对不同特征家庭进行进一步检验发现，相比于农村家庭、中西部地区家庭和中低收入家庭，互联网使用水平对城镇、东部地区和高收入家庭消费结构升级有着更全面和更强的促进效果。 |

| Abstract: By adopting the data from the China Family Panel Studies (CFPS), and based on factor analysis, this paper measures the level of household Internet usage from three levels: basic usage, usage range and frequency, usage depth and importance, and builds a QUAIDS model to explore the impact of Internet usage on the upgrading of household consumption structure. The study finds that the impact of the level of Internet usage on the upgrading of household consumption structure includes the promotion effect and the inhibition effect, that the promotion effect is reflected in the decline in marginal consumption of food which belongs to necessities, and in the increase in marginal consumption of items in education, entertainment, daily necessities, and miscellaneous items which belong to luxury, and that the higher the household consumption level, the more obvious the promotion effect of the Internet usage level. The inhibition effect is reflected in the increase in the marginal consumption of clothing, transportation and communication which belongs to necessities, and in the decrease in the marginal consumption of health care and housing which belongs to luxury items. This mainly originates from the fact that the Internet has stimulated household consumption demand and willingness, saving household consumption costs at the same time. By further testing households with different characteristics, the results show that compared with rural households, households in central and western regions, and low- and middle-income households, the level of Internet usage has a more comprehensive and stronger effect on the upgrading of consumption structure in urban, eastern and high-income households. |
