报告摘要：

As the largest soybean importing country, this study examines the overweight effects of the soybean import shock (Soybean-Overweight Shock: SOS) on Chinese. Exploiting prefecture-level variations in the extensive soybean import liberalization in 1996, we found large and reasonable SOS effects: a one-standard-deviation reduction in prefecture-level import tariffs on soybeans is associated with a 2.6% increase in the probability of becoming overweight, with tariff reductions on soybeans accounting for an 8% increase in the overall prevalence of overweight across China after trade liberalization. In this way, exposure to a soybean import shock significantly reduces the market price for soybean oil, which consequently leads to an increase in people’s total caloric and fat intake. We also discovered that people who eat out are often exposed to greater SOS effects than those who primarily eat in at home, while those individuals who prefer the cooking methods adopted when preparing stir-fried and deep-fried foods were meanwhile also found to feature higher SOS effects.
