摘要数字信息技术的广泛应用对生产生活产生了重大影响，在经济增长和人民福
祉方面更是尤为突出。本文在完成数字信息技术对多维贫困的影响研究之上，进
一步讨论了社会资本的中介作用。而就数字信息技术的应用而言，在不同的区域，
对于不同收入水平的家庭及同一地区的城乡居民都有不同的影响。
为实现完整全面对于问题的衡量，本文采用中国家庭面板研究（CFPS）数
据库用于数据处理，并采用中介效应模型对问题进行研究。数字信息研究发现，
技术使用可以从社会网络、社会参与和社会信任三个方面提升社会资本，进而缓
解多维贫困。结果表明，在数字信息技术对于多维贫困的影响传导中，社会信任
比社会资本和社会参与具有更显著的中介作用。
此外，研究结果还表明数字信息技术的使用对于不同的收入水平群体具有不
同的影响，对于低收入群体具有更大的影响。这体现了数字信息技术具有的普惠
性特征，通过将接受信息的门槛、交通的门槛、通讯的成本降低，使得低收入人
群也能获得在数字信息技术改革中的收益，有效促进低收入人群增收，降低贫困
水平。在社会资本的中介效应中，高收入群体的中介效应显著高于低收入群体的
社会资本中介效应，尤其在收入位于最高的25%的人群中，他们的社会资本具有
最高的中介效应，这一结果反映出社会资本作为一种特殊的资本，其所表现出的
并非通常所认为的边际效应递减。而是更多地体现为，只有高质量的社会资本才
能对生计生活产生明显的作用，而通常而言，非贫困群体拥有比贫困群体更高质
量的社会资本水平，而也就因此能够更多从社会资本中获益。
在对城乡多维贫困状况进行异质性的分析中，发现城乡多维贫困状况存在显
著差异。城镇地区的数字信息技术使用程度明显优于农村地区，而城镇地区也因
拥有较高水平的社会资本，因而导致其对于城镇的多维贫困状况具有较为优异的
缓解作用。
对于总体回归而言，本文认为，数字信息技术可以全面改善所有群体的多维
贫困状况，而其对于多维贫困的缓解中，社会资本起到了重要的中介作用，而在
社会资本的中介作用中，进一步看到了其中社会信任承担的重要作用，因此本文
认为，依靠数字化的进步信息技术，可以建立更方便的社交网络，建立更充足渠
道信息沟通，增强社会信任和社会参与，并有所缓解多维贫困。

Abstract
Abstract
The wide application of digital information technology has a significant impact
on production and life,economic growth and people's well-being.This paper
evaluates the mediating role of social capital and the impact of digital information
technology on multidimensional poverty.The application of digital information
technology in different regions has different impacts on families with different income
levels and urban and rural residents in the same area.
In order to achieve a complete and comprehensive measurement of the problem,
this paper uses the Chinese Household Panel Research (CFPS)database for data
processing,and uses the mediation effect model to study the problem.Research on
digital information shows that technology use can improve social capital and social
trust from social network,social participation and social capital,thus alleviating
multidimensional poverty.The results show that social trust is more significant than
social capital and social participation in mediating the multidimensional poverty of
digital information technology.
In addition,the research results also show that the use of digital information
technology has different impacts on different income levels,and has a greater impact
on low-income groups.This reflects the universal benefits of digital information
technology.By reducing the threshold of receiving information,the threshold of
transportation and the cost of communication,low-income people can also gain
benefits in the reform of digital information technology,effectively promoting the
income increase of low-income people and reducing the poverty level.In the
mediation effect of social capital,the mediation effect of high income group is
significantly higher than that of low-income groups the intermediary effect of social
capital,especially in income is located in the top 25%of the crowd,their social
capital have the highest intermediary effect,the results indicated that social capital as
a special kind of capital,the show is not usually as diminishing marginal effect.It is
more that only high-quality social capital can have a significant impact on livelihood,
and generally speaking,non-poor groups have a higher level of quality social capital
than poor groups,and therefore can benefit more from social capital.
In the heterogeneity analysis of multidimensional poverty in urban and rural
areas,it is found that there are significant differences in multidimensional poverty in

Abstract
urban and rural areas.The degree of digital information technology use in urban areas
is obviously better than that in rural areas,and urban areas also have a higher level of
social capital,which leads to an excellent alleviating effect on multidimensional
poverty in urban areas.
For general regression,this paper argues that digital information technology can
improve every aspect of multi-dimensional poverty of all groups,and its for ease of
multidimensional poverty,social capital plays an important role in the mediation,and
in the intermediary role of social capital,we saw one further assume the important
role of social trust,therefore this article think,With digital advances in information
technology,we can build more convenient social networks,create more channels for
information communication,enhance social trust and engagement,and alleviate
multidimensional poverty.

poverty,mediating effect,bootstrap test；
