基于投入产出视角的区域数字鸿沟成因分析

The Cause Analysis of Regional Digital Divide from an Input-output Perspective

目前区域数字鸿沟形成原因的研究主要集中在成因因素的确定上,而忽视了这些因素在数字鸿沟形成过程中作用发挥程度的差异。基于投入产出视角,引入生产理论分析,发现区域数字鸿沟的成因有两个:一是"数字化"生产要素投入数量差异造成区域要素投入不足或冗余,二是"数字化"生产效率差异造成区域要素生产潜力发挥程度的不同。综合应用因子分析、线性回归和DEA方法对我国区域数字鸿沟成因进行实证研究,所得实证结果与理论分析相一致。研究表明,要快速高效地弥合区域数字鸿沟,必须在生产效率最大的前提下,增加"数字化"生产要素投入数量。

Currently,research on the causes of regional digital divide mainly focus on determining the cause factors of the divide and rarely concern the discrepancy in the degree that these factors play their roles.Based on an input-output perspective,and by introducing production theory,we find that there are two reasons for the formation of regional digital divide,one is that difference in input of ″digital″ production factors leads to elements＇ input deficiency or redundancy,the second is that difference in ″digital″ production efficiency results in the divergence in the degree of elements＇ potential utilization for production.The results from empirical research done on causes of regional digital divide in China by use of factor analysis,linear regression and DEA methods comprehensively confirm the conclusions from theoretical analysis.In order to bridge the digital divide efficiently at a high speed,it is necessary and imperative to increase the input of ″digital″ production factors under the premise of the highest productivity.
