Abstract: How do product perishability and market connectivity jointly determine the propagation of climate shocks through food supply chains? Using 6.7 million daily wholesale price observations across 234 markets and 46 products in China (2017–2023) matched to typhoon track data, this paper documents that typhoon exposure raises wholesale prices by 4.1 percent within 100 km, with effects extending to 500 km but concentrated among vegetables. A triple-interaction specification reveals that the price response increases with operational perishability (β̂₁ > 0), decreases with market connectivity (β̂₂
