知识产权保护、技术距离与企业绿色技术创新“增量提质”

发布时间:2024-06-28作者:刘宇 张硕 梁栋浏览次数:10

摘要:企业绿色技术创新是我国绿色低碳发展的重要动力,亦是企业提高核心竞争力的重要渠道,探究知识产权保护能否促进我国企业绿色技术创新“增量提质”对推动新质生产力发展以及实现“双碳”目标有着重要影响。本文借助知识产权示范城市政策的准自然实验,基于20072021年沪深A股上市公司数据探究了知识产权保护对于企业绿色技术创“增量提质”的作用。研究发现:示范城市政策在整体上促进了企业绿色技术创新“增量提质”,然而该促进作用依赖于企业与前沿技术水平的距离,政策显著促进了接近技术前沿企业的绿色技术创新“增量提质”,对于远离技术前沿企业的影响并不显著;进一步从行业特征来看,政策显著促进了高科技行业、不易被反向工程行业、低集中度行业以及低碳行业企业的绿色技术创新“增量提质”;增加企业研发投入和强化企业社会责任是知识产权示范城市政策提升企业绿色技术创新表现的两个渠道。本文为科学构建产权保护政策以激励企业绿色技术创新行为提供了有益的政策启示。

Intellectual Property Protection, Technology Gap and “Quantity Increase and Quality Improvement” of Green Innovation

Liu Yu, Zhang Shuo, Liang Dong

Abstract: Enterprise green innovation is an important driving force for China's green and low-carbon development, as well as an important channel for enterprises to improve their core competitiveness. Exploring whether intellectual property protection can improve the quantity and quality of enterprise green innovation has a significant impact on promoting the development of new quality productivity and achieving the Carbon Peak and Carbon Neutrality Goals. This paper takes the intellectual property demonstration city policy as a quasi-natural experiment, based on the data of A-share listed companies in Shanghai and Shenzhen from 2007 to 2021 to explore the effects of intellectual property protection in improving the quantity and quality of enterprise green innovation. The results show that the demonstration cities policy has improved the quantity and quality of enterprise green innovation as a whole. However, this promotion effect depends on the technology gap. The policy significantly improves the quantity and quality of green innovation in enterprises close to the technological frontier, but the impact on quantity and quality of green innovation in enterprises far from the technological frontier is not significant. Furthermore, from the perspective of industry characteristics, policies have significantly improved green innovation in high-tech industries, industries that are not easily reverse engineered, low concentrated industries, and low-carbon industries. Increasing R&D investment and strengthening corporate social responsibility are two channels for intellectual property demonstration city policies to enhance the green innovation performance of enterprises. This paper enriches the existing research on the impact of intellectual property protection on green development from a micro enterprise perspective, providing useful policy insights for scientifically constructing intellectual property protection policies to encourage enterprises green innovation behavior.
