材料分析题

2011年8月5日，国际评级机构标准普尔公司宣布将美国AAA级长期主权信用评级下调一级。在欧洲、希腊、爱尔兰、葡萄牙相继爆发债务危机，作为欧元区第三大经济体的意大利也卷入漩涡，欧债危机蔓延至欧元区核心经济体，市场传言法国会成为下一个丧失AAA评级的经济体。

主权债务危机的成因复杂。首先，金融危机是西方主权债务危机的导火索，金融危机使得政府税收锐减，为了救市刺激经济使得财政赤字大增；其次，信贷经济是主权债务危机的根源，以美国为例，过去数十年沉湎于“信贷经济”，从政府到个人负债累累；最后，体制缺陷是债务危机深化的主要原因，以欧洲为例，欧元区存在天生的体制缺陷，即货币政策和财政政策的“二元性”—仅仅统一货币政策而未统一财政政策。

国际货币基金组织认为，未来西方国家将长期处于入不敷出的窘境，人口老龄化、退休金、社保和医保等开支，将压得各国政府喘不过气来。

（1）如何看待“信贷经济”的作用？从经济生活角度，谈谈欧美债务危机的发生给我国经济社会平稳健康发展的启示。

（2）主权评级从一个侧面反映出一国的国家信用度。保持良好的国家信用度，政府责无旁贷。运用政治生活知识，说明我国政府在保持我国良好的国家信用度方面应该有的作为。
