Does e-commerce narrow the urban–rural income gap? Evidence from Chinese provinces
利用2002-2018年中国省级面板数据，研究发现电子商务有助于缩小城乡收入差距，但该效应仅在电商发展中等以上且城镇化水平较低的地区显著，公共支出和教育水平高的地区效果更强。
Purpose A wide urban–rural income gap exists in China despite the implementation of pro-rural policies. Additionally, with the proliferation of the internet and information technology, the promotion effect of e-commerce on the economy has become apparent. Accordingly, China has been actively encouraging rural households to participate in e-commerce activities. This study aims to examine the effect of e-commerce on the urban–rural income gap. Design/methodology/approach In the study, linear and panel threshold models were applied to provincial-level panel data from 2002 to 2018. Findings The results of the linear model show that e-commerce contributes to narrowing the urban–rural income gap. Moreover, the panel threshold model results show that the narrowing effect exists in regions where the e-commerce intensity is at a medium-to-high level and urbanization is at a relatively low level; otherwise, e-commerce has no effect. In addition, in regions with a relatively high level of public expenditure and education, the income-gap-narrowing effect of e-commerce is more than double. Practical implications The urban–rural income gap can be reduced by promoting e-commerce and reducing the urban–rural divide in e-commerce use. Originality/value To determine how varying levels of e-commerce development affect the urban–rural income gap across regions, the study proposes four key causes of the digital divide in e-commerce: e-commerce intensity, public expenditure level, urbanization level and education level and applies the variables as threshold variables to examine the non-linear effect of e-commerce on the income gap.
