两化融合对工业创新效率影响的突变性研究

基于两部门创新生产模型,构建了两化融合影响工业创新效率的理论模型.运用面板回归和门槛回归的方法证明了两化融合对工业创新效率的促进作用并非简单线性的,而是随着两化融合水平的提高发生了两次递增性突变.进一步研究表明,这种突变性是由于不同外部环境水平的约束造成的.在样本区间内,两化融合对工业创新效率的促进作用随着信息化基础设施水平的提高发生两次递增性的突变;随着经济发展水平和经济开放度的提高发生一次递增性的突变.

A Study on the Mutability of the Impact of Integration of Informatization and Industrialization on the Efficiency of Industrial Innovation

Based on the two-sector innovation production model, a theoretical model for the integration of informatization and industrialization to influence industrial innovation efficiency was constructed. The panel regression and threshold regression methods were used to prove that the promotion effect of the integration of informatization and industrialization on the efficiency of industrial innovation is not simply linear, but has also experienced two incremental mutations as the level of integration of informatization and industrialization has increased. Further research shows that this mutation is caused by the constraints of different external environmental levels. In the sample interval, the promotion of integration of informatization and industrialization on industrial innovation efficiency has two incremental mutation with the improvement of informatization level, and one incremental mutation with the improvement of industrialization level and degree of economic openness.
