Since genetically modified crop / food (GMC/GMF) was commercially planted in 1996,the cultivation of GMC has continued to keep rapid and stable growth in recent 14 years in the world.Meanwhile,the debates on whether GMF are safe,whether GMF should be commercially planted and whether GMF should be labelled or not have never stopped.In fact,these problems are mainly involved in social assessment of GMF.Social assessment standards of GMF include three standards:unity of production and quality,unity of efficiency and justice and unity of interests and responsbilities,which jointly construct a social assessment standard system of GMF.
