数字贸易对制造业绿色低碳转型的影响研究

Research on the Impact of Digital Trade on the Green and Low-carbon Transformation of Manufacturing Industry

绿色低碳转型是制造业高质量发展的必然要求,数字贸易为此提供了良好契机。本文通过选取2013—2021年中国省级面板数据,考察数字贸易对制造业绿色低碳转型的影响。研究发现,数字贸易整体上促进制造业绿色低碳转型。数字贸易四个维度对制造业绿色低碳转型的促进作用从大到小依次为:数字贸易能力、创新要素基础、对外贸易潜力、基础设施环境。数字贸易对沿海地区制造业绿色低碳转型具有显著的促进作用,对内陆地区的影响不显著;在产业集聚、人力资本水平高的地区,数字贸易的促进效应更强。数字贸易主要通过技术创新、消费升级和要素配置等渠道推动制造业绿色低碳转型,且存在显著的知识产权单一门槛效应。

Digital trade presents a significant opportunity for green transformation,which has become an indispensable requirement for the high-quality development of the manufacturing industry.The purpose of this study is to conduct an empirical analysis on how digital trade affects the green and low-carbon transformation of China’s manufacturing sector,utilizing provincial panel date from 2013 to 2021.The research finds that digital trade promotes the green and low-carbon transformation of the manufacturing industry as a whole.The four dimensions of digital trade,namely digital trade capacity,innovation factor foundation,foreign trade potential,and infrastructure environment all contribute to promoting the adoption of eco-friendly and sustainable practices in the manufacturing sector,but the effects vary.Coastal areas benefit greatly from digital trade in facilitating the green and low-carbon transformation of their manufacturing industry,whereas inland areas experience a relatively insignificant impact in this regard.In regions characterized by a higher concentration of industries and a greater level of human capital,there is an observed significant facilitative impact in the domain of digital trade.It facilitates the transition of the manufacturing sector towards environmental sustainability and reduced carbon emissions,primarily through technical innovation,consumption upgrading,and factor allocation.This approach exhibits a significant impact on intellectual property rights with a prominent single-threshold effect.
