中国高技术产业技术多元化对持续创新的影响研究

Research on the Influence of Technological Diversification on Persistent Innovation in China’s High-Tech Industry

技术多元化是高技术产业持续创新的重要前提和基础,探讨其中的作用机理具有重要价值。在回顾相关理论的基础上,提出高技术产业技术多元化对持续创新的影响效应、外部技术获取与改造和技术多元化模式调节效应的基本假设,并利用中国高技术产业1998—2020年的面板数据进行实证检验。研究结果表明:①高技术产业技术多元化对持续创新(技术和产品)的促进作用具有门槛效应,存在“最优区间”;②外部技术获取与改造正向调节高技术产业技术多元化和持续创新的关系;③基于技术间知识关联度和核心技术能力两个维度,可将高技术产业技术多元化划分为高关联-强核心、低关联-强核心、低关联-弱核心和高关联-弱核心四种模式;④不同模式的技术多元化对高技术产业持续创新的促进效应存在差异性,“高关联-强核心”型技术多元化更有利于技术持续创新提升,“低关联-强核心”型技术多元化则更有利于产品持续创新提升,“低关联-弱核心”型技术多元化对持续创新的促进效应最弱。

Technological diversification is an important prerequisite and foundation for the persistent innovation of high-tech industry,and it is of great value to explore the mechanism of its role.On the basis of reviewing relevant theories,the basic hypotheses of the influence of technological diversification in high-tech industry on persistent innovation,the moderating effect of external technology acquisition and transformation and technological diversification pattern were put forward,and empirical tests were carried out using the panel data of China’s high-tech industry in the period of 1998-2020.The results show as follows.Firstly,the promotion effect of technological diversification on persistent innovation(technology and product)in high-tech industry has a threshold effect and there exists an“optimal interval”.Secondly,external technology acquisition and transformation positively moderate the relationship between technological diversification and persistent innovation in high-tech industry.Thirdly,based on the two dimensions of technology relatedness and core technology competence,the technological diversification of high-tech industry can be divided into four patterns:high relatedness-strong core,low relatedness-strong core,low relatedness-weak core and high relatedness-weak core.Fourthly,there are differences in the promotion effect of different patterns of technological diversification on the persistent innovation of high-tech industry.The“high relatedness-strong core”type of technological diversification is more conducive to persistent innovation of technology,the“low relatedness-strong core”type of technological diversification is more conducive to persistent innovation of product,and the“low relatedness-weak core”type of technological diversification has the weakest promoting effect on persistent innovation.
