数字经济对流通产业结构高级化的影响研究——基于STR模型非线性效应的实证分析

Research on the influence of digital economy on the advanced structure of circulation industry——Empirical analysis based on the nonlinear effect of STR model

数字经济驱动产业创新是现代商业模式更迭以及产业转型升级的核心驱动力。本文构建2012-2019年时间序列的STR模型,实证检验数字经济影响流通产业结构高级化的非线性效应。研究发现:数字经济对流通产业结构高级化的驱动效果显著,存在跨越门槛值后的驱动力非线性特征,且数字产业总产值对流通产业结构高级化的作用具有延展性,产业规模和行业集中度在线性区制内与产业结构高级化之间存在明显衰减的弱关联关系;数字经济与流通产业结构的高级化之间存在结构转变和速度转变的非线性特征,数字产业总产值和增加值在阈值附近的转换速度较快,移动网络接入流量和国家研发占比在"低-高"区制转换中未产生"跳跃"式驱动。本文最后提出强化流通产业数字基础设施建设和强化数字经济与流通产业发展的深度融合等对策建议。

Digital economy driving industrial innovation is the core driving force of modern business model change and industrial transformation and upgrading.This paper constructs the STR model of the time series from 2012 to 2019,and empirically tests the nonlinear effect of digital economy on the promotion of circulation industry structure.Study found:the digital economy circulation industry structure is the fundamentals of the drive effect is remarkable,there is a driving force of the nonlinear characteristics after crossing the threshold value,and the digital industry output value the role of the high-level structure of circulation industry is malleable,industry scale and industry concentration area in linear system with high-level industrial structure obvious attenuation weak correlation between;There are nonlinear characteristics of structural transformation and speed transformation between digital economy and the advanced structure of circulation industry.The conversion speed of the total output value and added value of digital industry is fast near the threshold value.There is no"jump"drive in the"low-high"zone transformation of mobile network access traffic and national R&D proportion.Finally,this paper puts forward some countermeasures,such as strengthening digital infrastructure construction of circulation industry and deepening integration of digital economy and circulation industry development.
