基于B2C模式上的F2F商务模式

21世纪是全球电子商务高速发展的时代,短短十几年的时间里电子商务B2B、B2C、C2C已经逐渐发展壮大,而一种全新的从工厂到家庭(F2F)商务模式已经渐渐加入了电子商务的浪潮。本文主要在B2C模式的基础上介绍F2F模式、以及F2F模式的实例和发展前景。随着互联网的高速发展,F2F模式因其线上与线下结合的直销模式特点,将是电子商务的下一个掘金点。

C2C电子商务模式下顾客忠诚度提升策略

C2C模式下的网络卖家从以前的一枝独秀,因其竞争对手B2C模式下电商的快速发展,像B2C模式下的网络卖家正在不断借鉴C2C模式的优秀做法,扩充商品种类,同时保持自身优势进行规模采购、垂直营销,专注于细分市场,形成比C2C模式下的个人卖家更有竞争力的价格,这使得C2C卖家地位早已动摇,利润也被大大挤压出去,发展是十分困难。

B2C和C2C的市场建设比较分析

随着互联网技术的日益普及,电子商务迅猛发展。B2C和C2C作为电子商务主要的两种模式,在推动电子商务发展方面起到了巨大作用。随着电子商务的进一步发展,两种模式融合的趋势越来越明显,因此加强B2C和C2C模式的比较研究,推动两种模式的更好融合,就具有重要的理论和实践意义。     

B2B2C模式对销售渠道的影响研究

随着电子商务在中国爆发式的增长,电子商务的模式也出现百花齐放的现象,B2B2C模式作为一种符合目前中国国情的大势所趋的处于高速发展中的复合型电子商务模式,B2B2C模式是B2B和B2C两种电子商务模式的整合:以B2C为基础,以B2B为重点,将两个商务流程紧密结合,从而形成一种新的电子商务模式,对销售渠道的结构、流程、功能和管理都带来巨大影响。     

价格战攻势退居次席电商巨头争相上马开放平台

B2C开放平台越发成为电商们的必争之地，而随着价格战的偃旗息鼓，包括天猫、京东、苏宁在内的电商巨头纷纷在平台的营销模式上下起了工夫     

电商税收流失测算与治理研究

B2C、C2C模式作为电商零售领域的代表模式,目前存在问题较多的是B2C模式,该模式成为税务机关的征税盲区,存在一定程度的税收流失。文章对电商税收流失问题采取社会实验方法进行抽样调查和流失额测算。国内电商平台以阿里巴巴旗下的淘宝、天猫最为成熟,故而选取淘宝、天猫两个电商平台上的电器、服装、食品、图书、酒水、家具、化妆品七大行业420家网店进行测试,对抽样网店的工商税务登记、发票开具情况等重点内容进行随机暗访测试。电商税收流失测算部分主要估测增值税和个人所得税的流失额,根据阿里巴巴官网公布的电商交易额数据和百货零售业、超级市场零售业、综合零售业的增值税平均税负率等三种口径测算电商C2C模式下的增值税流失额;根据阿里巴巴官网公布的电商交易额数据和个人所得税平均税负率的经验值估测个人所得税流失额,并推演至全国电商平台,测算全国C2C模式下的税收流失额。最后,基于电商税收流失测算结果,提出关于电商税收流失的治理对策。     

RANK TESTS IN 2X2 DESIGNS

Abstract. In literature numerous attempts can be found for the evaluation of two factor designs with fixed effects by means of rank tests. The aim of the present article is to show the limits of these methods and to give some new procedures for 2X2 designs. First, functionals of distribution functions shall be defined whose relations to the usual parameters of the linear model are analysed. These functionals are free of nuissance parameters under the respective hypothesis; they are estimated by special ranks of the data. The asymptotic distribution of these statistics is derived by a generalization of the Chemoff–Savage theorem for correlated random variables. The asymptotic variance depends on the parent distribution function but it can be estimated by using special rank methods. Thus, one obtains asymptotically distribution–free tests for two–factor designs with fixed effects. Some counter examples show why it is not possible to construct suitable rank tests for greater designs than the 2X2 design. The paper closes with a discussion of the drawbacks of the well known rank transform.     

Jackknife estimators of a relative risk in 2×2 and 2×2×K contingency tables

Several jackknife estimators of a relative risk in a single 2×2 contingency table and of a common relative risk in a 2×2× K contingency table are presented. The estimators are based on the maximum likelihood estimator in a single table and on an estimator proposed by Tarone (1981) for stratified samples, respectively. For the stratified case, a sampling scheme is assumed where the number of observations within each table tends to infinity but the number of tables remains fixed. The asymptotic properties of the above estimators are derived. Especially, we present two general results which under certain regularity conditions yield consistency and asymptotic normality of every jackknife estimator of a bunch of functions of binomial probabilities.     

A response to LDR 2 LDR: KNEX 2 U

An act of leadership is always an act of practical theory. We lead because we hold visions of the world as it ought to be, because of the not yet, because of the potential that we see in ideas and people. Yet, there still exists a perceived binary between leadership theory (in the strong sense) and leadership practice, a binary that divides organizations, classrooms, and the differing bodies of leadership literature. In this Symposium, Duncan Waite and his colleagues discuss the barriers they have faced in bringing theory to the educational leadership classroom, as well as the promise they feel theory holds for more productive, equitable, and humane schooling organizations.

Rank tests for the 2×2 split plot design

Summary In the 2×2 split plot design there are given rank tests for the classical hypotheses of the main effects and interaction.The asymptotic normality of the proposed teststatistics is proved and their consistency is investigated. For testing the main effects these methods cannot be extended on the generala×b split plot design Counter-examples are given.     

商界G2

G2，是一些国际媒体在经济危机爆发后推出的概念，由G8、G20演变而来，意谓现在世界政经格局由中美两国大致主宰，中美之间的竞争、合作和对话，足以判定大势。其实，在眼下中国的服务与消费产业，也有G2现象，只不过，这儿的G不再代表Government（政府），不妨以Giant（巨头）取代之。一中一外两大企业巨头，或者中外两种势力，在服务消费领域形成对峙，若论本土成长性，前者占优。
