摘　　要：数字经济的发展带来了产业数字化和数字产业化,提高了产业活力,而在数字经济发展过程中,不同行业的数字技术投入水平可能是导致行业利润率差异的因素之一。本文从理论上分析了数字技术投入水平与行业利润率之间的关系,利用我国2017年149个行业的投入产出表数据,检验了狭义数字技术投入水平对行业利润率的影响。研究结果表明:新一代数字技术投入水平有助于提升行业经营状况,改善行业盈利能力;而传统数字技术投入水平已经成为生产和经营中的常规技术,不能解释行业间利润率的差异。据此本文提出建议:要大力推进新一代数字技术的研究,推动企业加大数字技术投入水平,推动数字技术与产业深度融合,以数字经济发展促进产业升级。The development of the digital economy has brought industrial digitization and has improved the vitality of the industry.The level of digital technology input in different industries may be one of the factors that lead to the difference in industry profitability.This paper analyzes the relationship between digital technology input level and industry profitability.Using the data of the input and output tables of 149 industries in 2017,it examines the impact of narrow digital technology input levels on industry profitability.The results show that:The input level of new-generation digital technology can improve the industry’s operating conditions and profitability,while the traditional digital technology input level cannot explain the difference in profitability between industries.Based on this,this article proposes:we must promote the research on the new generation of digital technology,enterprises to increase the input level of digital technology,the deep integration of digital technology and industry,and industrial upgrading through the development of the digital economy.
