Co‐control of the haze pollution emissions in China: Insight from supply chains.

This article focuses on analyzing the co-control of three major haze precursors—volatile organic compounds (VOCs), sulfur dioxide (SO2), and nitrogen oxide (NOx)—in China from 2007 to 2017, using environmentally extended input–output analysis, structural path analysis, and structural path decomposition methods. The study identifies fixed capital formation, particularly investment in construction, as the most critical final demand driving emissions of these pollutants. It highlights that from 2007 to 2012, the key supply chain path increasing emissions was "transportation and warehousing→household consumption," whereas from 2012 to 2017, "electricity, gas, and water supply→household consumption" became the dominant path contributing to emission reductions. Changes in direct emission intensity were found to be the primary driver of emission changes in these supply chains, followed by changes in final demand, suggesting that coordinated adjustments in both production and consumption supply chains are essential for effective haze pollution mitigation in China.
