知识产权保护对制造业企业绿色创新效率的影响研究
Research on the Impact of Intellectual Property Protection on the Green Innovation Efficiency of Manufacturing Enterprises
摘要
Abstract
Against the backdrop of the accelerating global transition towards green and low-carbon development,green innovation has emerged as a pivotal driver for high-quality economic growth.To delve deeper into the impact mechanisms of intellectual property protection on the green innovation efficiency of manufacturing enterprises,this study utilizes panel data from A-share listed manufacturing companies in China from 2009 to 2022.Adopting a two-stage innova-tion value chain perspective,the research segments green innovation efficiency into green tech-nology R&D efficiency and green achievement transformation efficiency.Employing a two-way fixed effects model and a mediation effects model,the study conducts an empirical analysis.The findings reveal that intellectual property protection significantly enhances both green technology R&D efficiency and green achievement transformation efficiency in manufacturing enterprises.Mechanism tests indicate that intellectual property protection indirectly improves green innova-tion efficiency by increasing R&D investment intensity and alleviating financing constraints.Heterogeneity analysis demonstrates that the promoting effect of intellectual property protection on green innovation efficiency varies significantly across different types of enterprises,regions,and industries.Based on these findings,this study proposes the following policy recommenda-tions.Firstly,further refine the intellectual property protection system and optimize the patent approval process.Secondly,promote the construction of industry-university-research coopera-tion platforms to achieve resource sharing and technological collaboration.Thirdly,optimize the financing ecosystem through deepened green finance reforms,including launching dedicated low-interest loans and green bond issuance mechanisms to ensure sustained funding for green technology adoption.Fourthly,implement differentiated policies in response to enterprise types and regional heterogeneity to boost regional collaborative innovation capabilities and accelerate the green and low-carbon transformation of the manufacturing industry.This study not only en-riches the literature on the relationship between intellectual property protection and the green in-novation efficiency of manufacturing enterprises,but also makes significant theoretical and prac-tical contributions from multiple perspectives.Based on the research findings,it puts forward tar-geted policy recommendations,providing policymakers with theoretical and practical references.Committed to promoting the green innovation development of enterprises,this research holds great theoretical and practical significance for optimizing the green innovation environment of China's manufacturing industry,facilitating regional coordinated development,and achieving the"dual carbon"strategic goals.关键词
