摘要
数字经济作为推进经济发展的助推器,能否缩小城乡收入差距?是推进共同富裕进程中值得思考的命题。在理论分析的基础上,基于2011—2019年中国31个省(区、市)面板数据,采用中介效应模型、个体时间双向固定的空间面板杜宾模型实证检验数字经济对城乡收入差距的影响机制及其空间溢出效应。研究发现:2011—2019年中国省级城乡收入差距持续缩小且呈现“西高东低”的地理格局,数字经济发展水平有明显增长且呈现“东高西低,南高北低”的地理格局。计量结果显示,数字经济对城乡收入差距的影响呈现先缩小后扩大的“正U型”关系;产业集聚在两者关系中起到中介作用;金融支持起到调节作用,延迟了数字经济扩大城乡收入差距的起始时间。进一步研究发现,数字经济对城乡收入差距存在负向显著的空间溢出效应,在不同地区存在空间分异,即在东、中和西部地区呈“正U型”关系,在东北地区呈“倒U型”关系。为更好地发挥数字经济缩小城乡收入差距的作用,需加大金融支持力度、推动产业集聚发展;推动数据要素跨域流动,统筹智慧城市与数字乡村建设,推动城乡一体化进程。
As a booster to promote economic development, can digital economy narrow the urban-rural income gap?It is a proposition worthy of consideration in the process of promoting common prosperity.On the basis of theoretical analysis, based on the panel data of 31 provinces(autonomous regions and municipalities)in China from 2011 to 2019,this paper uses the mediating effect analysis model and the SPDM model based on time and entity two-way fixed effects to test the impact mechanism of the digital economy on the urban-rural income gap.The study found that the provincial urban-rural income gap in China in 2011-2019 showed a geographical pattern of“high in the west and low in the east”,and the development level of digital economy increased significantly, showing a geographical pattern of“high in the east and low in the west, high in the south and low in the north”.The measurement results show that the impact of the digital economy on the urban-rural income gap presents a“positive U-shaped”relationship that first narrows and then expands;Industrial agglomeration plays a mediate role in the relationship between the two;Financial support plays a moderate role, delaying the starting time of digital economy to expand the urban-rural income gap.Further research shows that the digital economy has a negative and significant spatial spillover effect on the urban-rural income gap, and there is spatial differentiation in different regions, that is, there is a“positive U-shaped”relationship in the east, middle and west regions, and an“inverted U-shaped”relationship in the northeast region.In order to play the role of digital economy in narrowing the urban-rural income gap better, it is necessary to increase financial support and promote the development of industrial agglomeration;promote the cross-regional flow of data elements, coordinate the construction of smart cities and digital villages, and propel the process of urban-rural integration.
