技术创新与产业升级的互动机制

The Interaction Mechanism of Technological Innovation and Industrial Upgrading

将技术创新分为自主创新与技术模仿,基于2008~2014年省级面板数据,以市场化指数为门槛变量,建立面板联立方程的门槛模型,分别探讨它们与产业升级之间的非线性相互影响机制。研究发现,自主创新对产业升级的影响没有门槛效应,自主创新总能显著正向影响产业升级;技术模仿对产业升级的影响具有单一门槛效应:市场化指数低于门槛值的省份,技术模仿对产业升级有显著正向影响,而超过门槛值的省份,其影响不显著;产业升级对自主创新的影响显著为正且存在单一门槛效应;市场化指数高于门槛值的省份,其影响程度远大于低于门槛值的省份;产业升级对技术模仿的影响存在双重门槛效应:在低市场化指数的省份,其有显著正向影响,在中市场化指数省份,其影响不显著,在高市场化指数省份,其影响显著为负。

Technology innovation is divided into independent innovation and technology imitation,to respectively explore nonlinear interaction mechanism between them and the industrial upgrading.Based on the provincial panel data from 2008to 2014,the threshold model of the panel simultaneous equation is set up and the marketization index is taken as the threshold variable. The empirical results find that there is no threshold effect for the impact of independent innovation on industrial upgrading and independent innovation always has a significant positive impact on industrial upgrading.There is single threshold effect for the impact of technology imitation on the industrial upgrading:technology imitation has a significant positive impact on industrial upgrading in provinces with a marketization index below the threshold value,while it has no significant impact in provinces with index beyond the threshold value.There is a single threshold effect for the impact of industrial upgrading on independent innovation:when the marketization index of the provinces is higher the influence of the threshold value,it is far greater than that of the provinces below the threshold value.There is a double threshold effect on the impact of industrial upgrading on technology imitation:it has a significant positive effect in in provinces with low marketization index,the impact is not significant in the provinces with medium marketization index,and the impact is significantly negative in the provinces of high marketization index.
