中文摘要：

美国联邦政府将管理农场生产经营风险的一系列支持计划统称为农场安全网,具体包括主要针对农业生产经营中市场风险的农产品计划、主要针对农业生产经营中自然风险的农作物保险计划以及对上述两个计划未覆盖风险进行补充的农业灾害援助计划。2014年美国农业法案对其农场安全网的内容和结构进行调整,试图构建一个各支持计划间有机组合、注重补贴效率和强化风险管理的新农场安全网。新农场安全网下的综合支持量虽然不会超过美国在WTO的减让承诺,但增加美国农产品贸易争端的潜在范围,降低美国在WTO新协议中削减＂黄箱政策＂补贴的意愿,对世界农产品贸易产生重要影响。新农场安全网一方面将加剧我国农产品进口压力,另一方面对我国农业补贴政策改革有如下启示：继续加大支持保护力度;坚持市场化改革方向;健全农业保险制度。

英文摘要：

The federal government of United States will manage the risk of farm production and farm business through a range of support programs, which are collectively known as the farm safety net including commodity programs mainly for the market risk, crop insurance programs mainly for the natural risk and agricultural disaster assistance programs for the risk not covered by the above two plans. 2014 United States farm bill adjusted the content and structure of the farm safety net, trying to build an organic combination among commodity programs ,crop insurance programs and agricultural disaster assistance programs, focus on subsidies efficiency and strengthen risk management. The new farm safety net could make AMS no more against American reduction commitments, increase American potential range of agricultural products trade disputes, and reduce the willingness of the USA to cut ＂yellow box policy＂ subsidies in the new WTO agreement, which have an important impact on world trade of agricultural products. The new farm safety net will aggravate the pressure of imports of agricultural products for China, and have the following enlightenment to agricultural subsidy policy reform of China： continue to intensify protection of support; adhere to the market-oriented reform direction; improve the agricultural insurance system.
