Digitalization is an excellent opportunity for the manufacturing industry all over the world to improve the core competitiveness and break through the "low-end locking" dilemma. However, it is not clear whether the digitalization of the manufacturing industry has positive ecological and environmental benefits under the resource and environmental constraints. To answer this question, we use the data from the world input-output database (WIOD) to investigate the impact of manufacturing input digitalization on carbon emission intensity by an extended analysis. The results show that the input digitalization of the manufacturing industry has mixed effects on reducing carbon emission intensity. The productive input digitalization can reduce carbon emission intensity, but the distributional input digitalization may increase carbon emission intensity. Non-pollution-intensive manufacturing and high-input digital manufacturing have stronger carbon emission reduction effects than the other industry sectors. From the perspective of input sources, input digitalization from domestic sources has a significant inhibitory effect on the carbon emission intensity. In contrast, input digitalization from foreign sources may increase carbon emission intensity.
数字化是全球制造业提高核心竞争力、突破“低端锁定”困境的绝佳机遇。然而,在资源环境约束下,制造业数字化是否具有积极的生态环境效益尚不清楚。为回答这一问题,我们利用世界投入产出数据库(WIOD)的数据,通过扩展分析研究了制造业投入数字化对碳排放强度的影响。结果表明,制造业投入数字化对降低碳排放强度具有混合效应。生产性投入数字化可以降低碳排放强度,但分配性投入数字化可能会增加碳排放强度。非污染密集型制造业和高投入数字化制造业比其他行业部门具有更强的减排效果。从投入来源看,国内来源的投入数字化对碳排放强度具有显著的抑制作用。相比之下,国外来源的投入数字化可能会增加碳排放强度。
