在美国产品责任法中,风险-效益标准是认定产品设计是否存在缺陷的重要标准。在我国的产品责任法中,对产品设计缺陷的认定标准实质上是消费者期待标准,该标准在对复杂产品以及存在明显危险的产品的设计缺陷的认定方面,存在着明显的不足,因此无法很好地保护消费者的利益。本文建议将风险-效益标准引入我国产品责任法中,并在使用该标准时,将本由原告承担的举证责任转移给被告。 In the United States Product Liability Law, the risk-benefit criterion is an important criterion for determining whether a product's design is flawed.

The standard has obvious deficiencies in the design defects of complex products and obviously dangerous products, and therefore can not Good protection of the interests of consumers. This paper proposes to introduce the risk-benefit standard into our country's product liability law, and when using this standard, transfer the burden of proof which the plaintiff should bear to the defendant.
