互联网技术的普及和发展为中国的经济提供了健康、稳定和快速发展的驱动 力，同时在推动居民消费等各个领域发挥着重要的作用。在商品信息的传播方面， 互联网的出现使居民可获取到更多关于商品消费的资料，使得更多的消费途径能 够被社会大众理解并且接受，互联网的出现改变了居民消费模式；电子商务是一 种新型的商业经营模式，互联网商务是电子商务活动中的组成成分之一，也是现 代化的信息技术手段，新的消费模式打破了居民固有的消费习惯，在提高了当地 居民消费效率的同时，增强了对于商品的消费要求。本文首先对 CFPS2018 年数 据进行初步的分析，然后对互联网使用对居民消费的影响进行深入的研究，对互 联网与居民消费这一方面的文献补充起到了重要的作用。 文章首先通过梳理国内外相关文献得出互联网使用对居民消费有着非常重 要的影响，介绍了本文的主要内容和研究方法，定义了互联网使用、居民消费变 量的概念，以及 2018 年的居民消费与互联网的发展现状，在此基础上对 2018 年 居民消费、互联网使用、户口类型、婚姻状况与对互联网的重视程度等变量采用 描述性统计、列联表分析、卡方检验等统计方法探讨这些变量之间的关系。其次 研究互联网使用对居民消费的影响，通过分析互联网使用对居民消费的影响机制， 为后面的实证部分奠定基础，基准回归模型表明：互联网使用可以提高居民消费， 对居民消费的影响是正向的。选用家庭平均对互联网的态度作为工具变量，用 2SLS 解决了互联网使用可能存在的内生性问题。最后分析互联网使用对居民消 费的异质性，使用分位数回归法分析互联网使用对居民消费层次和居民消费类型 的影响，使用基准回归探索互联网使用对不同地区、不同收入阶层的影响、经济 发展程度不同地区的影响。研究结果表明：分位数从 10%等间距增加到 70%分位 点的时候，互联网使用的回归系数表现为：先下降后缓慢上升的趋势，说明互联 网使用对居民消费的条件分布的两端影响小于对中间部分的影响；使用互联网对 农村和城镇地区的居民家庭消费均有显著的促进作用，互联网使用在农村地区对 居民消费的影响大于城镇地区；与低收入阶层相比，互联网使用对高收入阶层的 影响更为明显；对与经济发达的地区，人口是经济发展的资本，人口的增加可以 促进经济的发展，而对于经济欠发达的地区，人口的增加在一定的程度上限制经兰州财经大学硕士学位论文 互联网使用对居民消费的影响—基于 CFPS2018 年数据的实证分析 济的发展，对经济的发展起到了阻碍作用。

The popularity and development of Internet technology has provided a healthy, stable and rapid driving force for China's economy, At the same time in the promotion of consumer consumption and other areas have played an important role .With regard to the dissemination of commodity information, the emergence of the Internet has made it possible for residents to obtain more information on commodity consumption,making more consumption channels understood and accepted by the public. The emergence of the Internet has changed the consumption pattern of residents. E-commerce is a new type of business model, Internet commerce is one of the components of e-commerce activities is also a modern information technology,the new consumption patterns to break the inherent consumption habit,at the same time of improving the efficiency of the local residents' consumption,and enhances the consumer demand for goods. Based on this,this paper first conducts a preliminary analysis of CFPS2018 data, Then the impact of Internet use on residents' consumption is deeply studied, which plays an important role in supplementing the literature on Internet and residential consumption. This paper firstly concludes that Internet use has a very important impact on residents' consumption by combing relevant literature at home and abroad, and introduces the main content and research methods of this paper. Defines the concept of Internet use and consumer variables, as well 兰州财经大学硕士学位论文 互联网使用对居民消费的影响—基于 CFPS2018 年数据的实证分析 as the status of residents' consumption and the development of the Internet in 2018, on the basis of the residents' consumption in 2018, the types of Internet use, registered permanent residence, marital status and the degree of attention to the Internet and other variables by means of Statistical methods such as descriptive statistics, list analysis, chi-square test and so on explore the relationship between these variables .Secondly,it studies the influence of Internet use on residential consumption. By analyzing the influence mechanism of Internet use on residential consumption,it lays the foundation for the following empirical part. The benchmark regression model shows that Internet use can improve residential consumption and has a positive impact on residential consumption. By using the average attitude of the family to the Internet as the tool variable, the possible endogenous problem of Internet use is solved by 2SLS.Finally,The heterogeneity of Internet use on residents' consumption, and the influence of Internet use on residents' consumption level and consumption type by quantile regression method ,The baseline regression method was used to observe the influence of Internet use on different regions, different income classes and regions with different levels of economic development. The results show that when the quantile increases from 10% to 70%, the regression coefficient of Internet use shows a trend of decreasing first and then rising slowly, which indicates that the influence of Internet use on the two ends of conditional distribution of residents' consumption is less than 兰州财经大学硕士学位论文 互联网使用对居民消费的影响—基于 CFPS2018 年数据的实证分析 that on the middle part. The use of the Internet has a significant effect on household consumption in rural and urban areas, and the impact of Internet use on household consumption in rural areas is greater than that in urban areas.Compared with low-income groups, the impact of Internet use on high-income groups is more obvious；For economically developed areas, population is the capital of economic development, and the increase of population can promote economic development, while for economically underdeveloped areas, the increase of population restricts and hinders economic development to a certain extent.
