   本网讯(通讯员:张鹃)根据2017年初的最新数据,我院方晶老师的合作论文”China’s Rising IQ (Innovation Quotient) and Growth : Firm-level Evidence”(合作者Hui He, Nan Li)入选国际货币基金组织工作论文系列(IMF Working Paper)。

 

        该文基于一个独特的,包括1998-2007年间的工业企业信息和专利数据,来检验中国近年来快速增长的专利活动,是否和真实的经济产出联系在一起。作者们发现了很强的证据,来支持企业专利数量与企业绩效正相关的观点。除此以外,此文还发现,虽然平均来看,国有企业在绩效和创新方面水平比私营企业都更低,但是迅速增长的专利,给予国有企业更快速的生产率增长。

 

Abstract

This paper examines whether the rapid growing firm patenting activity in China is associated with real economic outcome by building a unique dataset uniting detailed firm balance sheet information with firm patent data for the period of 1998-2007. We find strong evidence that within-firm increases in patent stock are associated with increases in firm size, exports, and more interestingly, total factor productivity and new product revenue share. Event studies using first-time patentees as the treatment group and non-patenting firms selected based on Propensity-Score Matching method as the control group also demonstrate similar effects following initial patent application. We also find that although state-owned enterprises (SOEs) on average have lower level of productivity and are less innovative compared to their non-state-owned peers, increases in patent stock tend to be associated with higher productivity growth among SOEs, especially for patents with lower innovative content. The latter could reflect the preferential government policies enjoyed by SOEs.

KEY WORDS:

Keywords: Innovation, Growth, Patent, R&D, Productivity, SOE Reforms, China
