数字化转型对区域高技术产业创新差距影响研究

Research on the impact of digital transformation on the innovation gap of the regional high-tech industry

高技术产业在推动区域创新协调发展中发挥重要作用,研究数字化转型对高技术产业创新差距的影响对于优化创新空间格局,提升科技创新整体实力具有重要意义。本文在分析数字化转型对创新差距影响机制的基础上基于省级面板数据进行研究,并运用面板回归模型、分位数回归模型、面板门槛模型及BVAR模型实证分析数字化转型对创新差距的影响规律与互动关系。结果表明:(1)总体而言数字化转型对创新差距表现出显著的缩小作用;(2)从区域看,东部地区省份数字化转型拉大了创新差距,而中西部地区省份数字化转型则有利于缩小创新差距;(3)随着创新差距的不断扩大数字化转型对其的缩小作用逐渐变小;(4)当数字化转型处于较低与较高水平时,其对创新差距呈现出显著的缩小作用,且当数字化转型水平较高时这种缩小作用表现的更强;(5)创新差距的不断拉大抑制了数字化转型水平的提升,数字化转型与创新差距呈现出负向互动关系。因此,不同地区应立足自身发展的实际制定数字化发展策略,更好发挥数字化转型在缩小创新差距、实现创新收敛中的作用,同时也要客观认识到创新差距的积极作用,既要防止没有创新差距更要防止过大的创新差距。

The high-tech industry plays an important role in promoting coordinated development of regional innovation.Studying the impact of digital transformation on the innovation gap of high-tech industries is of great significance for optimizing the innovation spatial pattern and enhancing the overall strength of scientific and technological innovation.This paper analyzed the impact mechanism of digital transformation on innovation gap based on provincial panel data,and used the panel regression model,quantile regression model,panel threshold model,and BVAR model to empirically analyze the impact law and interactive relationship of digital transformation on innovation gap.The results showed that:(1)digital transformation has,in general,shown a significant narrowing effect on the innovation gap;(2)from a regional perspective,the digital transformation of provincial-level regions in the eastern region has widened the innovation gap,while the digital transformation of provincial-level regions in the central and western regions is conducive to narrowing the innovation gap;(3)as the innovation gap continues to widen,the role of digital transformation in narrowing it gradually diminishes;(4)when digital transformation is at a low or high level,it shows a significant narrowing effect on the innovation gap,and this narrowing effect is stronger when the level of digital transformation is high;and(5)the continuous widening of the innovation gap has suppressed the improvement of digital transformation level,and there is a negative interactive relationship between digital transformation and innovation gap.Therefore,different regions should formulate digital development strategies based on their own actual development,better leverage the role of digital transformation in narrowing innovation gaps and achieving innovation convergence,while objectively recognizing the positive role of innovation gaps.It is necessary to prevent both lack of innovation gaps and excess of innovation gaps.
