摘要
研发支出会计政策变更会通过创新投入和创新产出对企业创新要素投资效率产生影响,同时研发费用税收政策变化会强化该影响。在总结研发支出会计政策变更和税收政策变化的基础上,以工业企业为例并与高新技术产业对照,运用瓦格勒模型对该影响进行了分阶段的实证检验,并据以提出改进和运用研发支出会计政策促进提高企业创新要素投资效率的建议。
Changes in accounting policies for R&D expenses affect investment efficiency of enterprise innovation factors through input and output of innovation,and changes of R&D expenses tax policies strengthen such influence.On the basis of summarizing the changes in accounting and tax policies for R&D expenses,by taking industrial enterprises as an example and comparing with high-tech industries,this paper uses the model created by Wurgler to carry out an empirical test for those impacts in phases,and suggests improving and using accounting policies for R&D expenses to boost the investment efficiency of enterprise innovation factors.
