绿色技术创新、碳排放与制造业升级

Green technology innovation,carbon emissions and manufacturing upgrading

基于梳理绿色技术创新与制造业升级的数理逻辑,运用2005—2021年我国30个省份的面板数据,构建双向固定效应模型,并引入碳排放这一中介变量,实证检验变量之间的影响作用。研究发现:(1)绿色技术创新可有效促进制造业合理化发展与高级化发展;(2)经过了内生性控制与稳健性检验后,结论依旧成立;(3)我国东、中西部地区因其经济发展、资源禀赋等因素不同,导致绿色技术创新对制造业升级的影响存在异质性;(4)碳排放存在中介效应,绿色技术创新可以通过削减碳排放来促进制造业升级。因此,在未来实现制造业升级过程中,要突破制造业,尤其是重污染行业绿色技术创新的瓶颈,突破“信息孤岛”,搭建绿色技术有效、安全交流平台,同时,促进制造业升级过程中要注意对环境的保护,避免通过绿色技术创新促进制造业升级过程中产生负的外部性。

Based on the mathematical logic of green technology innovation and manufacturing upgrading,a bi-directional fixed-effect model was constructed using panel data of 30 provinces in China from 2005 to 2021,and carbon emission as a mediator variable was introduced to empirically test the influence of the variables.The findings are as follows:(1)Green technology innovation can effectively promote the rationalization and advanced development of manufacturing industry;②After the endogenous control and robustness test,the conclusion of this paper is still valid;(3)The impact of green technology innovation on manufacturing upgrading is heterogeneous in the eastern and central regions of China due to their different economic development and resource endowment.(4)Carbon emissions have an intermediary effect,and green technology innovation can promote the upgrading of manufacturing industry by reducing carbon emissions.Therefore,in the process of upgrading the manufacturing industry in the future,it is necessary to break through the bottleneck of green technology innovation in the manufacturing industry,especially in the heavily polluting industry,break through the"information island",and build an effective and safe exchange platform for green technology.At the same time,it is necessary to pay attention to the protection of the environment in the process of promoting the upgrading of the manufacturing industry,and avoid negative externalities in the process of promoting the upgrading of the manufacturing industry through green technology innovation.
