Can Intellectual Property Protection Promote Firm Digital Innovation? A Firm Life Cycle Perspective

摘要:

在数字经济情境下,知识产权保护成为企业进行自主创新与提高市场竞争能力的重要手段。鉴于此,本文利用2011—2021年沪深A股上市公司和省级面板数据,实证检验知识产权保护对企业数字创新的影响效果及作用机制。研究表明:①从总体上看,知识产权保护能够促进企业数字创新;②分生命周期看,知识产权保护对数字创新的促进作用在成长期企业中更显著;③机制分析表明,知识产权保护可通过减少研发溢出和缓解融资约束两条路径促进企业数字创新;④异质性分析表明,知识产权保护对企业数字创新的促进作用在处于成长期的服务业企业、高科技企业、民营企业中表现更明显。研究拓展了数字创新影响机制研究的视角,为相关管理部门制定和完善知识产权保护政策提供理论参考,同时也为企业数字创新发展提供借鉴。

Abstract:

In the new context of the digital economy, intellectual property protection as an important means for enterprises to engage in independent innovation and improve market competitiveness. In view of this, panel data from A-share listed companies in Shanghai and Shenzhen from 2011 to 2021 and provincial-level data were used to test the impact and mechanism of intellectual property protection on enterprise digital innovation. The results show as follows. Overall, intellectual property protection can promote enterprise digital innovation. In terms of life cycle, the promotion effect of intellectual property protection on digital innovation is more significant in growing enterprises. Mechanism analysis shows that intellectual property protection can promote enterprise digital innovation through two paths: reducing R&D spillovers and alleviating financing constraints. Heterogeneity analysis shows that the promotion effect of intellectual property protection on digital innovation is more pronounced in growing service industry enterprises, high-tech enterprises, and private enterprises. The research expands the research perspective of digital innovation, provides theoretical reference for relevant management departments to formulate and improve intellectual property protection policies, and also provides guidance for enterprises to develop digital innovation.
