数字经济空间集聚结构驱动共同富裕——基于区域创新与产业结构升级的作用机理

Spatial Agglomeration Structure of Digital Economy Drives Common Prosperity--Based on the Mechanism of Regional Innovation and Industrial Structure Upgrading

本文以2011—2021年省域和城市面板数据为依据,先构建了“物质—精神—生态”三维系统的共同富裕评价体系并利用熵权法对其进行了测算,再运用静态面板模型、工具变量估计等实证考察了数字经济空间集聚结构对共同富裕的影响及其作用机制。研究发现:(1)东部地区共同富裕水平与数字经济多中心水平相较于中西部地区更高;(2)数字经济单中心空间集聚结构容易诱发垂直化的过度集聚空间地理现象,不利于全面推动共同富裕,而多中心空间集聚结构容易形成扁平化的空间联动增长模式,有助于全面推动共同富裕;(3)数字经济单中心空间集聚结构通过加剧区域创新要素配置失衡、产业结构布局失调而间接对全面共同富裕产生阻碍作用,而多中心空间集聚结构通过促进区域创新要素配置平衡、产业结构布局优化而间接对全面共同富裕产生推动作用。为扎实推动共同富裕,应主张促进数字经济做强做优做大、合理布局数字经济空间集聚结构以及强化路径依赖等举措。

Based on the provincial and urban panel data from 2011 to 2021,this paper firstly constructs the common prosperity evaluation system of a'material-spiritual-ecological'three-dimensional system and measures it using the entropy weight method,and then empirically investigates the influence of spatial agglomeration structure of digital economy on common prosperity and its functioning mechanism using static panel model and instrumental variables estimation.Then,we empirically examined the impact of the spatial agglomeration structure of the digital economy on common prosperity and its mechanism by using the static panel data model and instrumental variable estimation.It is found that:(1)The level of common prosperity and digital economy polycentricity is higher in the eastern region compared with the central and western regions.(2)The monocentric spatial agglomeration structure of the digital economy is prone to inducing vertical over-agglomeration of spatial geography,which is not conducive to the comprehensive promotion of common prosperity,while the polycentric spatial agglomeration structure is prone to the formation of flat spatial linkage growth patterns,which is helpful to the comprehensive promotion of common prosperity.(3)The monocentric spatial agglomeration structure of the digital economy indirectly hinders the overall common prosperity by exacerbating the imbalance in the allocation of regional innovation factors and the imbalance in the layout of industrial structure,while the polycentric spatial agglomeration structure indirectly promotes the overall common prosperity by facilitating the balance of the allocation of regional innovation factors and the optimization of the layout of industrial structure.In order to solidly promote common prosperity,the government should advocate initiatives such as promoting the strengthening and expansion of the digital economy,rationally laying out the spatial concentration structure of the digital economy,and reinforcing path dependence.
