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… 相似文献

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。 相似文献

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。 相似文献

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? 相似文献

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… 相似文献

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. 相似文献

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 θk+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. 相似文献

长期以来,规模经济理论阻塞了经济学家们对小企业存在和发展原因的分析,经济学家们面临要么承认规模经济导致的垄断性市场结构,要么肯定小企业的存在和发展的两难选择。本文将从协调规模经济与小企业存在之间矛盾的角度,分析小企业存在的一般原因。 相似文献

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. 相似文献

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. 相似文献

This paper establishes the existence of an invariant probability measure on the set Π of measure-preserving bijections of the unit interval. In fact, the measure may be further restricted to be a Baire-measure. This result is compared with Aumann's (1967) and Aumann and Shapley's (1974) impossibility theorems. 相似文献

In this paper we first give an elementary proof of existence of equilibrium with dividends in an economy with possibly satiated consumers. We then introduce a no-arbitrage condition and show that it is equivalent to the existence of equilibrium with dividends. 相似文献

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. 相似文献
