第31题: [简答题]分析国债不同偿还方式的优缺点。
参考答案:
(1)一次偿还
优点:国债还本管理工作简单、易行,且不必为国债的还本而频繁地筹措资金;缺点:集中一次偿还,有可能造成政府支出的急剧上升,给国库带来较大压力。
(2)分期偿还
优点:可以分散国债还本对国库的压力,避免集中偿还给财政带来的困难;缺点:频繁进行本金兑付,手续繁杂,工作量大。
(3)买进偿还
优点:给投资者提供了中途兑现的可能性,并会对政府债券的价格起支持作用;缺点:政府需为市场购销做大量繁杂的工作,对从事此项工作的人员有较高要求。
(4)抽签偿还
优点:可以分散国债还本对国库的压力,避免集中偿还给财政带来的困难;缺点:手续繁杂,工作量大。
(5)以新替旧

Thank you for calling the University Career Management Centre. The University Career Management Centre (UCMC) provides information, programs and services to help students in developing, refining and implementing their career objectives. UCMC Information Centre contains occupational, employer and graduate school information and comprehensive computer aided career planning and placement support. UCMC also operates two programs which will provide students out of the classroom experiences in the marketplace and working fields connected with their majors.
The cooperative education program, which is paid, gives students access to an on-going professional experience with business, industry and government
and enables students to receive from two to four semesters of actual on the job training directly related to their fields of study.
The internship program differs from cooperative education programs in that it generally is part-time, temporary work, which may be either paid or non-paid.
The purpose of the internship is to help students to meet their educational and personal expenses while they are in school. In addition, UCMC administers two services: the graduate student service and the international student service. The graduate student service offers opportunities for students to begin finalizing their post graduation plans and to make successful transitions from school to work. During the academic year, employers from business, industry and government visit UCMC to interview graduating students who are seeking employment.
The international student service provides opportunities for students to familiarize employment policies, job search techniques and the job market.
