全球贸易对鲨鱼割鳍法规的反应

Global shark mortality continues to rise despite increasing regulations aimed at limiting shark fishing and trade. Regulatory measures may influence shark product markets, but this relationship has been difficult to quantify because of fragmented and poorly resolved data. We present a global analysis evaluating the effects of domestic shark finning regulations on trade in shark products across 188 countries. Using causal inference methods and the Aquatic Resource Trade in Species database (2007–2020), we find weak and statistically insignificant effects of finning regulations on overall shark trade volumes. However, long-term trends suggest that countries adopting finning regulations tend to reduce exports, modestly increase imports, and maintain relatively stable domestic consumption. Our framework provides a broader approach for investigating the economic pathways and drivers of mortality associated with sharks and other traded wildlife species.
