摘要
随着数字经济的兴起,以数字化为动力,通过优化生产过程、提高资源利用效率,为制造业的绿色转型提供了新的机遇。本文采用固定效应、中介效应、门槛效应模型,以2012—2022年我国30个省市的面板数据为样本,实证研究了数字经济对制造业绿色转型的影响。结果显示,数字经济对制造业绿色转型起到显著的推动作用,且这种推动作用在不同地区、不同经济发展水平下存在异质性。基于此,本文进一步探讨了数字经济对制造业绿色转型的作用机制。门槛效应检验表明,当经济发展水平与产业结构达到一定门槛时,数字经济能够显著促进制造业绿色转型。
This paper takes 30 provinces and cities in China as the research object,and uses the panel data from 30 provinces and cities in China from 2012 to 2022 as samples.It adopts a fixed effects model,mediating effects model,and threshold effects model to conduct an empirical study on the effect of China’s digital economy on green transformation of the manufacturing industry.The research results show that the digital economy significantly promotes the green transformation of the manufacturing industry,and this promoting effect varies in different regions and at different economic development levels.Further mediating effect analysis shows that the digital economy has an indirect impact on the green transformation of the manufacturing industry by enhancing the intensity of research and development.The threshold effect test reveals the non-linear impact of the level of economic development and industrial structure on the promoting effect of the digital economy,that is,when the level of economic development and industrial structure cross a certain threshold,the digital economy will significantly enhance the green transformation of the manufacturing industry.
