绿色制造技术创新对制造业绿色发展的影响

THE IMPACT OF GREEN MANUFACTURING TECHNOLOGY INNOVATION ON THE GREEN DEVELOPMENT OF MANUFACTURING INDUSTRIES

本文针对绿色制造技术创新对制造业绿色发展的影响展开研究,基于2003—2019年中国27个制造业行业层面的数据,从污染行业异质性的视角,实证考察了绿色制造技术创新与制造业绿色发展的关系,进而分析了“双碳”目标下绿色制造技术创新对制造业绿色发展的影响机制及路径。主要结论是:(1)绿色制造技术创新能够显著提升制造业绿色发展;(2)绿色制造技术创新对重度污染制造业行业绿色发展作用更明显;(3)绿色制造技术创新可以通过节能减排效应、能源结构优化效应、知识溢出效应以及产业结构绿色高级化效应促进制造业绿色发展。由此得出以下政策建议:鼓励制造业进行绿色制造技术创新,并采取适当的激励与约束机制;加大能源结构优化力度,促进高效、低碳型能源制造业体系建设;完善绿色制造技术创新的知识产权保护制度,增强绿色制造技术创新成果转化能力;推动产业结构绿色高级化发展,形成以绿色知识、绿色制造技术密集型产业为主的产业结构。

This paper studies the impact of green manufacturing technology innovation on the green development of manufacturing industries.Based on the data of 27 manufacturing industries in China from 2003 to 2019 and from the perspective of the heterogeneity of polluting industries,this paper empirically examines the relationship between green manufacturing technology innovation and the green development of manufacturing industries.Moreover,this paper analyzes the influencing mechanism and path of green manufacturing technology innovation on the green development of manufacturing industries under the“car-bon peak and neutrality”goals.The main conclusions are:(1)Green manufacturing technology innova-tion can significantly improve the green development of manufacturing industries.(2)The green manufac-turing technology innovation has a more obvious effect on the green development of the heavily polluting manufacturing industries.(3)Green manufacturing technology innovation can promote the green develop-ment of manufacturing industries through the effect of energy saving and emission reduction,the effect of energy structure optimization,the effect of knowledge spillover and the effect of green and advanced in-dustrial structure.From the conclusions,the following policy recommendations are drawn:we should encourage the manufacturing industries to carry out green manufacturing technology innovation and adopt appropriate incentive and restraint mechanisms;we should advance energy structure optimization,and promote the construction of an efficient and low-carbon energy manufacturing system;we should improve the intellectual property protection system of green manufacturing technology innovation to enhance the a-bility to transform green manufacturing technology innovation achievements;we should promote the gren and advanced development of the industrial structure,and form an industrial structure dominated by green knowledge and green manufacturing technology-intensive industries.
