Description
Qianzi Wang and co-authors modeled in 2026 how worker movement softens the economic harm of workplace heat stress in China. Heat cuts worker output, and losses ripple through supply chains, but yearly models miss daily detail and worker flows. Their model used daily movement data across 313 Chinese cities to trace these ripples.
Yearly heat stress cost China about 2.6 percent of GDP, with supply chain spread driving most losses. Worker inflows to hot, industrial southeast regions offset local output drops, saving billions directly and more through the chain. Under a 2030 warming path, losses grow sharply, but paired industry and work-hour changes could cut them by about 30 percent.
