R&D税收优惠政策的激励效应分析——以高新技术企业为例

Analysis of Incentive Effect of Preferential Tax Policies on R&D of High-tech Enterprises

本文基于2008-2018年A股上市的高新技术企业的非平衡面板数据,对高新技术企业的税收优惠政策对其R&D的激励效应进行理论分析与实证检验。结果显示,税收优惠政策促进着高新技术企业的研发投入,且流转税优惠的激励作用要大于所得税优惠。在通过企业规模与性质分组分析后,可论断税收优惠政策对大型、非国有科技型企业的激励作用要大于中小型、国有企业。因此,要转变税收激励方式,对中小型、非国有企业给予更大的发展空间与税收优惠政策,使得我国的税收优惠政策具有普适性和普惠性。

Based on the non-equilibrium panel data of high-tech enterprises listed on A-share market from 2008 to 2018,this paper conducts a theoretical analysis and an empirical test on the incentive effect of tax incentives on R&D of high-tech enterprises.The results show that the preferential tax policy promotes the R&D investment of high-tech enterprises,and the incentive effect of turnover tax preference is greater than that of income tax preference,and the incentive effect of tax incentives on large and non-state-owned enterprises is greater than that of small and medium-sized enterprises.Therefore,it is necessary to change the way of tax incentives and give more development space to small and medium-sized and non-state-owned enterprises.
