阅读以下文字,请分析其论证在概念、论证方法、论据及结论等方面的有效性。600字左右。 在中国改革开放的字典里,“终身制”和“铁饭碗”作为指称弊端的概念,是贬义词。 其实,这里存在误解。 在现代企业理论中有一个“期界问题”(horizon problem),是指由于雇佣关系很短而导致职工的种种短视行为,以及此类行为对企业造成的危害。当雇员面对短期的雇佣关系,首先他不会为提高自己的专业技能投资,因为他在甲企业中培育的专业技能对他在乙企业中的发展可能毫无意义;其次,作为一个匆匆过客,他不会关注企业的竞争力,因为这和他的长期收入没有多大关系;最后,只要有机会,他会为了个人短期收入最大化而损害企业利益,例如过度地使用机器设备等等。 为了解决“期界问题”,日本和德国的企业对那些专业技能要求很高的岗位上的员工,一般都实行终身雇佣制;而终身雇佣制也为日本和德国企业建立与保持国际竞争力提供了保障。这证明了“终身制”和“铁饭碗”不见得不好,也说明,中国企业的劳动关系应该向着建立长期雇佣关系的方向发展。 在现代社会,企业和劳动者个人都面临着不断变化的市场环境。而变化的环境必然导致机会主义行为。在各行各业,控制机会主义行为的唯一途径,就是在企业内部培养员工对公司的忠诚感。而培养忠诚感,需要建立员工和企业之间的长期雇佣关系,要给员工提供“铁饭碗”,使员工形成长远预期。 因此,在企业管理的字典里,“终身制”和“铁饭碗”应该是褒义词。不少国家包括美国不是有终身教授吗既然允许有捧着“铁饭碗”的教授,为什么不允许有捧着“铁饭碗”的工人呢 (提示:论证有效性分析的一般要点是:概念特别是核心概念的界定和使用是否准确并前后一致,有无各种明显的逻辑错误,该论证的论据是否支持结论,论据成立的条件是否充分等。要注意分析的内容深度、逻辑结构和语言表达。)
