根据专利实施方式的差异将在沪深股市挂牌上市的122家医药股份有限公司划分为4类:内部研发型企业(A型)、合作偏好型企业(B型)、开放创新型企业(C型)、转让活跃型企业(D型)。基于2010—2014年的122家医药上市公司的面板数据,采用Eviews软件构建固定效应模型,从专利数量与专利质量两个维度审视这4类企业的技术创新策略与企业成长性之间的关系。结果显示,大部分专利指标对企业成长具有促进作用,不同类型的企业其专利对成长性所作贡献不一,本文针对不同类型企业提出了提升成长能力的建议。
According to the difference of patent implementation, 122 pharmaceutical companies listed in Shanghai and Shenzhen stock markets are divided into four categories: internal R & D enterprises (A type), cooperative preference enterprises (B type), open and innovative enterprises (C type ), Transfer of active enterprises (D type). Based on the panel data of 122 pharmaceutical listed companies in 2010-2014, Eviews software was used to construct the fixed effect model to examine the relationship between the technological innovation strategies and business growth of these 4 types of enterprises in terms of the number of patents and the quality of patents. The results show that most of the patent indicators have a positive effect on the growth of enterprises. Different types of enterprises make different contributions to their growth on the basis of their own patents. This article suggests different types of enterprises to enhance their growth ability.
