知识产权保护对企业数字技术创新的影响效应研究——来自中国上市公司的证据

摘要/Abstract

摘要： 知识产权保护是激励创新和完善创新资源的重要制度因素。本文从知识产权制度供给和知识产权司法保护两个维度构造了城市层面的知识产权保护指标，以2011—2021年中国沪深A股上市公司为研究样本，系统考察了知识产权保护对企业数字技术创新的影响及其作用机制。研究发现：知识产权保护能够显著促进企业数字技术创新，经过一系列稳健性检验后，上述结论依然成立。影响渠道检验表明，企业研发投入强度增加和数字化转型水平提升是知识产权保护赋能企业数字技术创新的重要途径。异质性分析结果表明，在国有企业、大规模企业和知识产权产业企业组别中，知识产权保护对企业数字技术创新的赋能作用更加显著。上述研究发现有助于深入发掘知识产权保护对企业数字技术创新的作用效果，这为政府有关部门利用知识产权保护激励企业数字技术创新提供了政策参考。

Abstract: Intellectual property protection is an important institutional factor for stimulating innovation and improving innovation resources. This paper constructs urban-level intellectual property protection indicators from two dimensions: intellectual property system supply and intellectual property judicial protection. Taking China’s A-share listed companies from 2011 to 2021 as research samples, this paper systematically examines the impact of intellectual property protection on enterprise digital technology innovation and the underlying mechanism. The study finds that intellectual property protection can significantly promote enterprises’ digital technology innovation, and the above conclusion still hold after a series of robustness tests. The influence channel test shows that the increase in the intensity of R&D investment and the improvement of the level of digital transformation are important ways for intellectual property protection to empower enterprises’ digital technology innovation. The results of heterogeneity analysis show that the enabling effect of intellectual property protection on digital technology innovation is more significant in the group of state-owned enterprises, large-scale enterprises and intellectual property industry enterprises. The above research findings are helpful for further exploring the effect of intellectual property protection on enterprise digital technology innovation, and thus provide policy reference for relevant government departments to use intellectual property protection to stimulate enterprise digital technology innovation.

Key words: intellectual property protection, enterprise digital technology innovation, R&D investment, digital transformation
