摘　　要：以2008—2011年中国创业板上市公司为样本,通过研究税收对企业创新活动的影响,为税收政策影响经济增长提供微观经验证据.实证结果发现,企业税收负担改变研发投资现金流敏感性.前期税收负担越高的企业,研发投资与现金流之间的敏感性越强;税收负担越高的企业,报告的研发投入强度也越高.实证结果说明,税收负担挤出创业板上市公司研发投资,同时也强化企业利用税收优惠政策进行避税的激励.挤出效应削弱企业创新能力,避税激励导致企业报告的研发投入强度偏离其真实研发投入水平.Taking the samples of ChiNext listed firms from 2008 to 2011, it provides the micro evidence on the impact of tax policy to economic growth through investigating the impact of tax on innovation activities of enterprise. The empir- ical results find out that tax burden can significantly change cash-flow sensitivity of R＆D investment. The higher the ex ante tax burden is, the stronger the sensitivity between R＆D investment and cash flow will be. The higher the ex ante tax burden is, the higher the reported R＆D investment density will be. The empirical results imply that tax burden in- troduces the crowd out R＆D investment and strengthens the incentives for enterprises to take advantage of tax preferen- tial policy to reduce tax burden. Crowd out effect weakens the innovation ability of enterprises. Tax evasion incentive causes enterprise to report R＆D input density diverging from its true level.
