Abstract:

Reducing the urban?rural income gap is an important part of China's steady promotion of common prosperity, and this paper studies the intrinsic connection between the level of digital economy development and the urban?rural income gap based on the panel data of 30 provincial?level administrative regions in China from 2013 to 2021. The results of the study show that digital economy is conducive to narrowing the urban?rural income gap, and the rationalization of industrial structure exerts a partial mediating effect; in regions with higher levels of human capital, the development of digital economy can effectively alleviate the urban?rural income gap, and the rationalization of industrial structure plays a complete mediating effect, however, in regions with lower levels of human capital, the digital economy does not have a significant impact; when the level of economic development is low, the digital economy will expand the urban?rural income gap, while when the level of economic development is high, the digital economy will narrow the urban?rural income gap. Based on this, suggestions have been put forward to promote the coordinated development of industrial digitization and digital industrialization, further promoting the rationalization of industrial structure, enhancing the level of human capital, and optimizing the environment for the development of digital economy, in order to maximize the effectiveness of the digital economy in promoting the optimization of industrial structure and narrowing the income gap between urban and rural areas.

Key words: Digital economy, Urban?rural income disparity, Industrial structure optimization, Mediating effect, Level of economic development

摘要：

缩小城乡收入差距是我国稳步推进共同富裕的重要内容。基于2013—2021年我国30个省级行政区的面板数据，研究了数字经济发展水平与城乡收入差距之间的内在联系。结果表明，数字经济有利于缩小城乡收入差距，且产业结构合理化发挥部分中介效应；在人力资本水平较高的区域，数字经济发展能有效缓解城乡收入差距，且产业结构合理化发挥完全中介效应，但在人力资本水平较低的区域，数字经济对城乡收入差距并不产生显著的影响；当经济发展水平较低时，数字经济会扩大城乡收入差距，而当经济发展水平较高时，数字经济会缩小城乡收入差距。基于此，提出了推动产业数字化和数字产业化协调发展、深入推进产业结构合理化、提升人力资本水平以及优化数字经济发展环境等建议，以发挥数字经济推动产业结构合理化及缩小城乡收入差距的作用。
