全国统一技术大市场建设背景下的知识产权保护与技术交易市场

Intellectual property protection and the market for technology

随着全国统一技术大市场的建设与发展,知识产权保护与技术交易之间的关系成为越来越重要的问题。基于微观企业参与技术交易市场的视角,研究知识产权保护对技术交易的影响。鉴于数据的可得性,主要研究专利交易。研究发现,知识产权保护强度越高,企业交易的专利越多。这个影响在考虑内生性后依然显著。知识产权保护对专利交易的影响主要通过降低交易成本和增加交易收益实现。异质性方面,融资约束强的公司和高科技行业的公司的专利交易受知识产权保护强度的影响更大。研究结论丰富了文献中影响技术交易的因素,并为政策供给和进一步激发技术市场活力提供了理论依据。

With the development of the market for technology,exploring the effect of intellectual property protection on technology trading is very important.This article studies this question with the patent trading data of China.We find that the higher the intensity of intellectual property protection,the more active firms are in the market for technology,with more patents traded.This result remains robust after considering endogeneity issues.The impact is mainly achieved by reducing transaction costs and increasing transaction returns.Heterogeneity studies show that companies with stronger financial constraints and companies in high-tech industries are more affected by the intensity of intellectual property protection in patent transactions.The findings enrich the literature on patent trading and provide important reference for policy supply.
