差异化是企业唯一的生存之道

差异化的最大敌人是增长，许多企业为了追求增长，不断地扩张产品线，分散力量，因而失去了差异化的特性。增长并非不好，但是追求增长不要改变原有的策略。最好的方式不是采取商品线延伸的策略（即以一个品牌发展多种商品），而是采取多品牌策略，即每个商品有单独的品牌，并拥有个别的差异化策略，如此每个品牌个性分明，市场可以扩大。譬如吉列（Ｇｉｌｌｅｔｔｅ）拥有５个品牌的刮须刀，因而占有 ６５％的市场。 因此，要做到“差异化”，必须做以下三个牺牲： 一、商品的牺牲：集中焦点在一种产品比分散在各种商品更有利，譬如肯德基…     

国外中小企业的生存之道

下列几个国家中小企业的生存之道,希望能给中国企业以鉴戒。     

DIY电脑中小商家的生存之道

不仅国家对DIY商家有3C认证的要求表示，而且品牌机一反昨日的沉默，明显加强了攻势，DIY商家尤其是中小商家的前途何在，生存空间在哪里，又有多大？这些问题都引起了DIY商家的深思。但从社会环境上分析来看，3C认证这几年并不会真正的实行，因为现在就业问题是我国很重要的问题，重要程度很高。而解决就业问题的重要途径是支持中小企业发展，DIY中小商家是典型的中小企业，吸纳了一定的就业，强制推行3C认证无异于将他们扫地出局。     

浅谈地市报的生存之道

地市报是我国报业家族中覆盖国土面积最广。覆盖人口数量最多的一个报纸群体。当我国进入社会主义市场经济阶段,办报模式也受到了前所未有的经济体制改革浪潮的冲击,处于党报群体中弱势地位的地市报如何生存发展成为地市报人共同关注的焦点问题。     

内卷时代的生存之道

物流行业已进入内卷时代,为了降低物流成本,一线卡友的利润空间不断被压缩,这不仅影响司机的职业发展,也对物流行业的发展非常不利。4月8日,在太原参加行业会议的合肥维天运通信息科技有限公司董事长冯雷提出,物流行业的竞争在不断地加剧,压低成本的弊端是所有企业都看得到的。     

隆力奇的生存之道

热带雨林中一个新出芽的树苗要想在众多大树中间存活、成材,必须找到遗漏阳光的缝隙．迅速吸收阳光和养分,拼命成长到枝叶不完全被其他树木遮盖的时候才能继续生长。这是热带丛林植物的生存法则。     

种地的生存之道

种地对很多人来说．是个很陌生的概念,特别是对80后、90后、00后、10后,可能不知种地为何物。按照产业划分,种地属于农业,也是最古老的产业。正因为是一个古老、经久不息的产业,其里面蕴含着一些学问、一些哲理。假定你是一个农民,只有一小块土地。     

日本国誉的创意生存之道

人们不必再为挑选礼品而苦恼,只需设定好预算并送出“礼优百”礼品目录就可以完成送礼的全过程。而收礼人也不再是被动接受,而是可以根据自己的喜好选购礼品。这是来自日本的创意,不知道在中国会不会形成一个潮流呢？     

微利时代的生存之道

据报道,国家统计局一位专家近期说,中国企业已进入“微利时代”。而伴随着微利时代的到来,市场竞争更加激烈,企业只有找准自己的比较优势,才能求得生存发展。正确的定位是前提。社会讲究分工,一个企业要想在激烈的市场竞争中求得生存发展,必须先弄清市场缺什么,自己最擅长做什么,从而找准自己的比较优势和生存之道。中国台湾地区制造业很发达,但是台湾有名气的自主品牌却不多,大部分企业是做代工,即为别的品牌厂商搞订单加工。这些企业并不是不能推出自主品牌,而是认识到做代工更能发挥自身优势,推出自主品牌反而胜算较低。适度的规模是保障…     

Satiation and existence of competitive equilibrium

In this paper, we introduce a new assumption concerning the (non)satiation property of preferences and establish the existence of a competitive equilibrium under it. The assumption is weaker than the standard nonsatiation assumption and “weak nonsatiation” introduced by Allouch and Le Van (2008). In particular, it allows preferences to be satiated only inside the set of individually rational feasible consumptions, while the two nonsatiation assumptions do not. It is also worth noting that just like the two nonsatiation assumptions, our new assumption depends solely on the characteristics of consumers.     

Pseudocontinuous functions and existence of Nash equilibria

In topological spaces, we introduce a new class of functions (pseudocontinuous functions) and we present some characterizations and properties. In particular, we show that any preference relation endowed of utility functions is continuous if and only if any utility is pseudocontinuous. A maximum theorem is proved for such a class of functions and connections with similar results are investigated. Finally, the existence of Nash equilibria for games with pseudocontinuous payoffs is obtained.     

On the existence of locally mvu estimators

It is proved that there exists an unbiased estimator for some real parameter of a class of distributions, which has minimal variance for some fixed distribution among all corresponding unbiased estimators, if and. only if the corresponding minimal variances for all related unbiased estimation problems concerning finite subsets of the underlying family of distributions are bounded. As an application it is shown that there does not exist some unbiased estimator for θ^k+c(ε≥0) with minimal variance for θ =0 among all corresponding unbiased estimators on the base of k i.i.d. random variables with a Cauchy-distribution, where θ denotes some location parameter.     

Characterization of the existence of semicontinuous weak utilities

In this paper we characterize the existence of semicontinous weak utilities for acyclic binary relations. We shall reobtain directly from that result sufficient conditions that are available in the literature.     

On the existence of walrasian equilibrium in large-square economies

An existence theorem for Walrasian equilibrium is demonstrated for an economy with a continuum of consumers and an infinite-dimensional commodity space, such as l₁ or c₀, having an ‘order-compatible’ basis.     

The existence of sampling designs with preassigned inclusion probabilities

Summary The question of the existence of a sampling design realizing given preassigned inclusion probabilities is treated. The question can be fully answered in the case of inclusion probabilities of first order. If the inclusion probabilities of second order are given it is shown why necessary and sufficient conditions for the existence of a corresponding sampling design can be derived only in very special cases.     

On existence in equilibrium models with endogenous default

The equilibrium concept defined by Dubey et al. ,  and  generates equilibria such that asset buyers could raise expected returns by paying more for the assets that they purchase. A simple example shows that, in fact, all equilibria may be return-dominated in that sense. Universal existence in the DGS model thus depends critically on the assumption that lenders are unable to exploit an obvious profit opportunity.     

交通安全宣传教育存在的问题及对策

文中针对我国目前交通安全形势的现状和交通安全宣传工作效率低的现实,阐述了新时期加强交通安全宣传教育的必要性。根据交通安全宣传教育的特征和新的社会、交通形势,提出了建设社会化的交通安全宣传教育体系的构想。     

Optimal investment with taxes: an existence result

We study the deterministic control problem of maximizing utility from consumption of an agent who seeks to optimally allocate his wealth between consumption and investment in a financial asset subject to taxes on benefits with first-in–first-out priority rule on sales. Short sales are prohibited and consumption is restricted to be non-negative. Such a problem has been introduced in a previous paper by the same authors where the first-order conditions have been derived. In this paper, we establish an existence result for this non-classical optimal control problem.
