摘要
税收优惠是各国政府采取的激励企业R&D投入的主要政策工具。本文建立回归模型,通过对103家样本企业的问卷调查统计分析,实证评价了我国现行R&D税收优惠政策对企业R&D投入的激励效应。结果表明。现行R&D税收优惠政策对企业R&D投入具有正的影响,但激励作用不明显,政府每减免企业R&D投入的1元钱税收,只能刺激企业增加R&D投入0.104元。究其原因,在于现行R&D税收优惠政策存在优惠范围较窄、与现行税制不协调等问题。因此,还须采取措施进一步完善现行R&D税收优惠政策,增强其有效性。
Tax Incentives is the main policy that all of the countries' governments adopt to incentive the enterprise's R&D investment. The article evaluates the performance of our existing R&D tax incentive policies on enterprise's R&D expenditures through the regression methodology and questionnaires of 103 sample corporations. The demonstration shows that: the existing tax policies can affect enterprise's R&D expenditures, but the effect is vague. One Yuan revenue reduction only can exchange 0. 104 Yuan enterprise' s R&D expenditures~ The reason is that our existing R&D tax incentive policies still have some problems, such as narrower scope of incentive and disagreement with existing tax policy. So some measures must be taken to improve the existing R&D tax incentive polices and strengthen it's validity.
