我国不同地区企业研发费用税前加计扣除政策实施效果对比——基于创业板公司的经验证据

摘要

In this paper,we chose 1586 panel data from the GEM companies in China from 2010 to 2014 as samples.We inspected the effect of super-deduction policy in different regions and the influence of regional innovation environmenton the effect.Previous researchers mostly began with a single region and paid much attention to the effect in just one region.They rarely considered the regional differences of the effect.The study has shown that,the overall effect of the policy is significant.Considering each specific area,there is an obvious regional difference.A further research has shown that the regional financial policy can improve the effect significantly,but regional market structure and regional economy gross have no a significant adjustment.%以2010-2014年我国创业板上市公司的1 586个面板数据为样本,对企业研发费用税前加计扣除政策在不同区域的执行效果和区域创新环境对该政策执行效果的影响进行检验.已有研究大都是从单一地区着手,着眼于加计扣除政策在某一个地区的执行效果,很少考虑到政策效果的区域性差异.文章研究发现,加计扣除政策在我国创业板上市公司的整体实施效果具有显著性,但具体到不同区域,该政策的实践效果存在着区域性差异.进一步研究发现,区域财政政策对加计扣除政策的执行效果具有显著性调节作用,区域市场结构以及区域经济总量对此并无显著性调节作用.
