问题 单项选择题

经济学家:如果一个企业没有政府的帮助而能获得可接受的利润,那么它有自生能力。如果一个企业在开放的竞争市场中没办法获得正常的利润,那么它就没有自生能力。除非一个企业有政策性负担,否则得不到政府的保护与补贴。由于国有企业拥有政府的保护和补贴,即使它没有自生能力,也能够赢利。
如果以上陈述为真,以下哪项陈述一定为真

A.如果一个企业有政策性负担。它就能得到政府的保护和补贴

B.在开放的竞争市场中,每个企业都是有自生能力的

C.如果一个企业没有自生能力,它就会在竞争中被淘汰

D.如果一个企业有政府的保护和补贴,它就会有政策性负担

答案

参考答案:D

解析: 考查复言命题推理。“除非一个企业有政策负担,否则得不到政府的保护与补贴”是一个必要条件的假言命题,“企业有政策性负担”是“企业能得到政府的保护与补贴”的必要条件,所以“企业能得到政府的保护与补贴”是“企业有政策性负担”的充分条件,即D项正确而A项错误;由“如果一个企业在开放的竞争市场中没办法获得正常的利润,那么它就没有自生能力”可知B项错误;国有企业即使没有自生能力也可能赢利,因此C项错误。
