知识产权保护对企业创新的实证影响研究

Empirical research on the impact of intellectual property protection on firms’ innovation

文章利用中国120个城市的工业企业数据,检验了城市层面的知识产权保护对微观企业创新的影响。结果表明,在同等条件下,一定程度的知识产权保护有助于企业创新,但随着知识产权保护力度的加大,将抑制企业的创新活动,两者呈倒“U”型关系。

This paper tries to investigate 120 cities on the firms’innovation with China industry business performance data.The results show that,under the same conditions,some degree of intellectual property protection will indeed promote the firms’innovation,but the impact will reverse if the intellectual property protection continued to be stronger,an inverted“U”shape curve existed between the intellectual property protection and firms’innovation.
