摘要
选取沪深A股2013—2018年科技类上市公司的年度数据作为研究样本,运用门槛模型和变量分析,发现企业债务杠杆率对企业创新绩效的影响曲线呈显著的U型。进一步发现当企业杠杆率小于66.06%时,增加企业杠杆率能更好地促进企业创新绩效的提高,反之则抑制。该研究在微观上丰富了企业债务杠杆率对企业创新绩效的影响效应的相关研究文献,为科技类上市公司制定相关政策提供了参考。
This paper selects the annual data of Shanghai and Shenzhen A-share technology listed companies from 2013 to2018 as the research sample, and uses threshold model and variable analysis to find that the impact curve of enterprise debt leverage ratio on enterprise innovation performance is significantly U-shaped. It is further found that when the enterprise leverage ratio is less than 66.06%, increasing the enterprise leverage ratio can better promote the improvement of enterprise innovation performance, otherwise, it will inhibit. This study microscopically enriches the relevant research literature on the effect of enterprise debt leverage ratio on enterprise innovation performance, and provides a reference for technology listed companies to formulate relevant policies.
