管理经济学名词解释
1.管理经济学：是一门研究如何把传统经济学的理论和经济分析方法应用于企业管理决策实践的学科。
2.机会成本：是指一项资源在被放弃的其他用途中可能获得的最高净收入。
3.边际分析法：是运用导数和微分方法研究经济运行中微增量的变化，用以分析各经济变量之间的相互关系及变化过程的一种方法。
4.增量分析法：是边际分析法在实际运用中的变形，只要分析一个方案引起的收入是否大于由此引起的成本即可。
5.委托—代理问题：现代企业制度下企业所有权和经营权是分离的，使所有者作为委托人，经营者作为代理人，由于目标差异，产生“委托-代理问题”。
6.需求的变动：除了价格之外，任何一种决定需求的因素发生变化时，需求曲线移动。
7.需求量的变动：在其他条件不变时，由于某种商品自身价格变动导致的该商品的需求数量的变动。
8.供给的变动：是指非价格因素变动，它导致供给曲线发生移动。
9.供给量的变动：是指价格因素发生变动它导致供给量沿供给曲线变动。
10.需求-供给分析法：就是通过绘制供给和需求曲线，可以分析供给、需求与价格之间的关系，还可以分析供需曲线背后诸因素对价格和市场交易量的影响的一种方法。

17.规模经济：指当企业扩大经营规模时单位成本下降，因而使效率提高及总成本下降。
18.范围经济：是指一个企业因从事多种产品的生产，而引起的长期平均成本降低的现象。
19.沉没成本：指决策前已经指出，或承诺要支出，因而是不受将来决策影响的成本，属于非相关成本。
管理经济学名词解释
名词解释：1、管理经济学：是一门研究如何把传统经济学的理论和经济分析方法应用于企业管理决策实战的学科。
2、边际分析法：是进行经济、管理决策的一种基本方法。
在这里，“边际”含有“边缘”和“新增”之意。
根据这一方法，一个方案是否值得采用，不是看其全部收入是否大于全部成本，而是看其新增的收入（边际收入）是否大于新增的成本（边际成本）。
根据边际分析法原理，利润最大化的决策规则是：使边际收入等于边际成本。
3、增量分析法是边际分析法的变形。
二者的共同之处是，判断一个方案对决策是否有利，都要看由此引起的收入是否大于由此引起的成本，即看它能否为决策者增加利润。
它们都体现了向前看的决策思想。
二者的区别公公在于，边际分析法分析的是变量的微量（或单位）变化对收入、成本或利润等的影响，增量分析法分析的则是某种决策对收入、成本或利润等的影响。
4、企业价值最大化：也就是说股东财富的最大化。
现代企业管理的理论办都把它当作企业决策的长期目标。
在这里，企业价值是指企业未来预期利润往返现值之和。
5、现代企业制度下的企业，所有权和经营权是分离的。
所有者（股东）并不直接经营企业，而是通过董事会启用经理人员来管理企业。
在这里，所有者是委托人，经理人员则是代理人。
所有者（股东）的目标是企业价值最大化（反映在酱市场上就是股票价格的最大化，即股东财富的最大化）。
经理人员追求的则是高薪和更多的福利。
所以，所有者的目标和经理人员的目标是有差异的；经理人员有可能以牺牲股东的利益为代价来谋求个人的利益。
这就是经济学中所说的委托—代理问题。
6、会计利润：等于销售收入与会计成本之差。
经济利润等于销售收入与机会成本之差。
计算会计利润的目的是报告企业的盈亏情况，以便投资者作为投资的根据、政府作为征税的根据等。
经济利润则是企业决策的依据。
7、机会成本是指资源用于次好的、被放弃的其他用途本来可以得到的净收入。
或者说，资源用于某一用途的机会成本就是必须放弃的次好方案的价值。

管理经济学资料名词解释2021名词解释（一）曾经考过的1.管理经济学：管理经济学是一门研究如何把西方传统经济学的理论和经济分析方法应用作企业管理决策课堂教学的学科。
2.边际分析法：边际分析法是微观经济学分析和研究资源最优配置的基本方法。
边际即“额外”、“新增”之意。
用边际分析法去来衡量一个方案或一个项目与否不利，就是必须把这个方案的额外成本（边际成本）与引发的额外收益(边际收益)相比较。
如果边际收益大于边际成本，就是不利的。
否则，就是有利的。
3.外显成本：企业实际的支出，通常能在会计帐上表现出来。
4.机会成本（4）：指如资源用于其他的、次好的用途所可能得到的净收入5.经济利润：指销售收入与机会成本的差额6.需求量（3）：所指在一定时期内，在一定条件下，消费者愿并且能够出售不起的某种产品或劳务数量7.供给量（2）：指在一定时期内，一定条件下，生产者愿意并有能力提供某种产品或劳务的数量。
8.公共物品：（2）：那些没有价格，因而价格机制对其生产和消费不起调解作用的物品称作公共物品。
指具备两个关键的特征：存有非竞争性、非排它性的产品和劳务9.需求的变动（2）：是指某商品在自身价格不变的条件下，由于其他因素变动所引起的该商品的市场需求数量的变动。
它整体表现为市场需求曲线的平行加速度10.市场需求弹性（2）：需求量对某种影响因素变化的反应程度11.价格弹性：需求量对价格变动的反应程度。
12.需求收入弹性（2）：需求量对消费者收入水平变化的反映程度13.市场需求的交叉弹性：一种产品的需求量对另一种有关产品价格变化的反应程度14.优势互补Fanjeaux：两种产品必须分拆采用，就可以对消费者产生更大的效用15.生产函数：反映生产的投入与产出之间的关系，反映在生产过程中，一定的投入要素女团所能够生产的最小产量。
16.边际收益递增规律（4）：如果技术维持不变，减少生产要素中某个要素的投入量，而其他要素的投入量不变，增加的投入量起初会使该要素的边际产量增加，增加到一定点之后，再增加投入量就会使边际产量递减。
Bwdaaxu管理经济学知识点
七夕，古今诗人惯咏星月与悲情。
吾生虽晚，世态炎凉却已看透矣。
情也成空，且作“挥手袖底风”罢。
是夜，窗外风雨如晦，吾独坐陋室，听一曲《尘缘》，合成诗韵一首，觉放诸古今，亦独有风韵也。
乃书于纸上。
毕而卧。
凄然入梦。

-----啸之记。
绪论：一．管理经济学与微观经济学的异同同：前者与后者都是研究企业的行为，都要根据对企业目标的假设，再结合企业内外的环境来研究。
异：（1）后者是一门理论科学，研究的是抽象的企业，而前者则是一门应用科学，研究的是现实的企业（2）后者是以企业的唯一目标是追求最大利润为假设的，而前者则认为实现企业的目标从短期看，只能是有条件地谋求尽可能多的利润，从长期看，则是追求企业价值的最大化（3）后者是以企业所处环境的全部信息已知为假设的，据此来研究企业行为的一般规律，而前者则认为企业的环境信息是不确定的，因而需要依靠多种学科的知识对有关数据进行预测和估计，在不确定条件下进行具体决策。
二、管经的理论和支柱主要有：建立经济模型，边际分析法，需求弹性原理，关于市场机制和市场竞争的基本原理，边际收益递减规律，机会成本概念和资金的时间价值。
三、管经的决策准则1、企业目标：企业分为短期目标和长期目标。
短期目标是多样化的，长期目标是实现企业长期利润的最大化。
2、利润的种类及其在决策中的作用：可分为会计利润和经济利润，经济利润是决策的基础。
几种特殊情况下的机会成本：（1）业主用自己的资金办企业——把这笔资金借出可得到的利息。
（2）业主自己兼任经理——他在别处从事其他工作可得到的薪水。
（3）机器原来闲置，现在用来生产某种产品——零。
（4）机器原来生产A，可得利润X元，现在改生产B——生产A可得到的利润X元。
（5）过去买进的物料，现在市价变了，其机会成本——按市价计算。
（6）按目前市价购进的物料、雇用的职工以及贷入的资金——与其会计成本一致。
（7）机器设备折旧——该机器设备期初与期未可变卖价值之差。
常用的经济术语的英文缩写及简要解释
常用的经济术语的英文缩写及简要解释经济学术语解释1、什么是CPI、通货膨胀、PPI和GNP缩减指数？消费者物价指数(Consumer Price Index)，英文缩写为CPI，是反映与居民生活有关的产品及劳务价格统计出来的物价变动指标，通常作为观察通货膨胀水平的重要指标。
如果消费者物价指数升幅过大，表明通胀已经成为经济不稳定因素，央行会有紧缩货币政策和财政政策的风险，从而造成经济前景不明朗。
因此，该指数过高的升幅往往不被市场欢迎。
例如，在过去12个月，消费者物价指数上升2。
3%，那表示，生活成本比12个月前平均上升2。
3%。
当生活成本提高，你的金钱价值便随之下降。
也就是说，一年前收到的一张100元纸币，今日只可以买到价值97。
70元的货品及服务。
一般说来当CPI>3%的增幅时我们称为Inflation，就是通货膨胀；而当CPI>5%的增幅时，我们把他称为Serious Inflation，就是严重的通货膨胀。
主要价格指数有三个：消费者价格指数CPI(Consumer’s Price Index)，生产者价格指数PPI(Producer’s Price Index)，GNP缩减指数(GNP Deflator)。
三种价格指数的计算方法基本一样，即各种商品的价格变化程度的加权平均。
不过，每一种价格指数计算中选择的商品篮子不一样。
计算消费者价格指数时，商品篮子中包含的典型市民的消费篮子。
所以，消费者价格指数也被称为生活成本指数。
生产者价格指数计算时，选取的商品篮子中包含的是生产资源。
GNP缩减指数则是一个更具综合性的指数，其计算中选取的商品篮子既包含消费品，也包含生产资源。
可以这样说，CPI是一个同步经济指标，PPI是一个先行经济指标。
一般来说生产者价格指数领先于经济3个月到半年，消费者滞后于经济3个月到半年。
CPI 可以显示目前经济状况，而PPI可以显示未来经济状况。
PPI计算的是厂商出售的价格，而CPI计算的是消费者购买的价格。
管理经济学名词解释
绪论
1、管理经济学：是一门研究如何把传统经济学的理论和经济分析方法应用于企业管理决策实践的学科。
2、经济模型：由经济变量之间的函数关系构成，通过建立经济模型来研究经济变量之间的因果关系，可达到科学地进行经济预测和经济决策的目的。
3、边际分析法：是微观经济学分析和研究资源最优配置的基本方法，是一种正确的决策思想，用其衡量一个方案或一项活动是否有利，就是要把这个方案或活动引起的额外成本（边际成本）与引起的额外收益（边际收入）相比，如果后者大于前者，就是有利的，否则就是不利的，这种决策方法体现了向前看的决策思想。
（3）交叉弹性为零，说明X产品价格的变动与Y产品的需求量没有影响，两种物品互相独立，互不相关。。
2、交叉弹性应用举例：
（1）分析价格、销售量及产品间的竞争关系。（2）经济上区分不同部门的标志。交叉弹性的绝对值大，说明产品之间的相关程度很大，反之，互不相关。
二、需求估计：指如何求得需求函数、需求曲线和需求弹性。有两种方法：一是进行市场调查，根据所得资料估计需求；二是根据积累的统计资料，用统计法估计。
（2）可替代的物品越多，性质越接近，|εp|就越大。即替代某商品的难易程度决定此商品|εp|的大小。
（3）购卖商品的支出在人们收入中所占的比重（比重大的|εp|大，比重小的|εp|小）。
（4）时间因素也影响弹性的大小（同样的商品，从长期看，|εp|就大，从短期看，|εp|就小）。
6、价格弹性应用：
（1）弹性需求时，降价能使销售收入增加；非弹性需求时，降价则会使销售收入减少，故销售收入一定在单元弹性时为最大。销售收入曲线形状为一条抛物线。
（2）边际收入MR：指在一定产量水平上，额外增加一个产量能使总收入增加多少。边际收入在需求量为零时最大，在弹性需求时为正值，在单元弹性时为零，在非弹性需求时为负值。
