基于所有制差异视角,采用中国战略性新兴产业2011~2014年上市企业的面板数据,运用门槛回归技术考察了研发投入对企业绩效的非线性影响效应。结果表明：研发投入强度对不同所有制企业绩效的影响均存在显著的三门槛效应;研发投入强度与企业绩效之间的非线性关系表现出明显的所有制差异;企业规模、金融支持、资本结构等因素对不同所有制企业绩效的影响也表现出显著的差异。

Based on the differences in ownership, this paper examines the nonlinear effects of R＆D investment on companies performance using threshold regression techniques by the panel data of listed companies in emerging strategic industries of China from 2011 to 2014. The results shows that, the effect of R＆D intensity on the increase in the performance of compa- nies with different ownership takes on significant three-threshold effect; the nonlinear relationship between R＆D intensity and companies performance shows significant differences in ownership ; the impacts of the company scale, financial support, capital structure and other factors on the performance of companies with different ownership also show significant ownership differences.
