中文摘要：

对科技政策实施结果及其影响进行分析和评估对政府完善科技政策意义重大。本文以国家层面发布的与产业技术创新相关性最强的454条技术创新政策为研究对象,基于柯布-道格拉斯生产函数,利用2000-2009年产业面板数据,对政策力度、政策稳定性与创新绩效进行了研究。结果表明：创新政策力度对技术绩效有显著促进作用,对经济绩效不显著;政策的不稳定性会抑制政策对技术绩效的激励;政策对绩效作用存在滞后效应。比较不同政策工具对创新绩效的影响,发现供给政策对创新的技术绩效有激励作用,环境政策对技术绩效和经济绩效有激励作用,需求政策对经济绩效作用显著。最后,提出应加大需求政策供给力度,完善创新政策体系等相关建议。
