Wenhuan Wang, Zijian Cai, Yongzhen Zhu, Dian Yu, Jingjing Zhan, Xiaoqi Li, Xiaoyu Wang
TL;DR
This study analyzes CO2 emissions in China's digital economy sectors through supply chains, identifying key drivers and offering strategies to reduce emissions.
Contribution
The study introduces a whole supply chain analysis of CO2 emissions in digital economy sectors using multiple perspectives and input-output frameworks.
Findings
The core digital economy sector leads in CO2 emissions from a consumption-based perspective, while industrial digitalization leads from consumption- and betweenness-based perspectives.
Interprovincial flows drive supply chain emissions from a consumption-based view, while labor compensation drives emissions from an income-based view.
Short high-carbon supply chain paths involve the power and heat production sector and industrial digitalization sector.
Abstract
As China’s digital economy sectors rapidly expand, the growing demand for coal-based electricity has become a significant source of CO2 emissions. However, the mechanism driving these emissions within supply chains remain unclear, hindering targeted carbon management. This study addresses this gap by providing a comprehensive analysis of CO2 emissions thorough the whole supply chain perspective, covering income-, production-, betweenness-, and consumption-based perspectives, along with upstream and downstream supply chain paths. It employs Leontief and Ghosh input-output (IO) frameworks and structural path analysis. The results indicate: (1) The core industry sector of the digital economy (CIDE) ranks highest in CO2 emissions from consumption-based perspective, while the industrial digitalization sector (IDS) ranks highest from both consumption- and betweenness-based perspectives.
