我国智能产业优惠政策对智能效率的影响效应实证研究——基于企业生产系统的微观视角

An Empirical Study on the Effect of Policy Support in China's Intelligent Industry on Intelligent Efficiency--Micro Perspective Based on Enterprise Production Systems

为辨明我国智能产业优惠政策对智能效率的影响效应,从企业生产系统的视角,构建智能产业优惠政策与智能效率的关系模型,采用我国智能上市公司数据分别进行固定效应回归和门槛回归分析。结果表明以企业生产大系统的智能效率为指标评价政策扶持的影响效应有失偏颇;优惠政策在企业生产子系统和大系统对智能效率的效应相互影响,对企业生产子系统的影响存在差异,需采取相应对策加以应对。

In order to identify the effect of support policies in China's intelligent industry on the intelligent efficiency,from the perspective of production systems in enterprises and based on Cobb-Douglas production function,the relationship model between fiscal subsidies and tax preference and intelligent efficiency;the data of China's intelligent listed companies are used for the fixed effect regression and threshold regression analysis of whole data and sub industry chain link data.The results show that it is biased to evaluate the effect of policy support based on the whole production system;the effect of supporting measures on efficiency of production subsystems and the whole production system varies and there is cross effect among those effects.So countermeasures shall be taken to improve the intelligent efficiency.
