第一是位置，第二是位置，第三还是位置

工业园区、经济特区在一个国家经济稳步快速发展中发挥着不可忽视的作用，这样的例子比比皆是，越南也不例外。到目前为止，越南国内已经建有154家注册在案的工业园区，多集中在北、中、南重要经济区域内。虽然这些工业园区对越南经济发展贡献巨大，但是，其中许多家正式投入运营多年，园内仍空空如也，只有少数工业园区的使用面积比率和发展速度达到开发商预计的目标。     

跨国农业垄断公司对中国农业产业链的多维渗透及破解思路

近年来,以ABCD四大粮商和孟山都等为主要代表的跨国农业垄断公司加速从资本、技术和服务领域对中国农业产业链进行渗透。在资本方面,跨国农业垄断公司已在中国进行深耕,并开始进入更多细分市场;在技术方面,对核心技术的高效转化和集中掌握使其占据了农业产业链的制高点;在服务方面,对贸易、加工、仓储等服务环节的渗透使其获得了高额利润。中国农业企业是抵御跨国农业垄断公司渗透的根本,但目前中国农业企业的竞争力整体上低于跨国农业垄断公司,未能掌握核心技术、因投资回报率低而不愿深耕农业以及市场机制被扭曲是中国农业企业竞争力不足的主要原因。面对跨国农业垄断公司的多维渗透,中国应加强“监督审查”以构筑农业产业发展安全网,强化“创新引领”以打造农业企业核心竞争力,主动“扎根县域”以厚植农业企业的国内发展根基,积极“乘船出海”以拓展农业企业的全球发展空间,坚持“市场主导”以优化农业企业运营市场环境,进而谋求中国农业企业与跨国农业垄断公司的竞争均势。     

Alliance competence, resources, and alliance success: Conceptualization, measurement, and initial test

This research examines the effect of an alliance competence on resource-based alliance success. The fundamental thesis guiding this research is that an alliance competence contributes to alliance success, both directly and through the acquisition and creation of resources. Using survey data gathered from 145 alliances, empirical tests of the hypotheses provide support for the posited explanation of alliance success. The findings indicate that an alliance competence is not only antecedent to the resources that are necessary for alliance success but also to alliance success itself. C.

理解凭单制:渊源、机制、模式及运用

凭单制作为政府改革工具,实质是在公共服务中引入市场机制的一种制度安排。它渊源于新自由主义经济学,从消费者角度通过强化其选择权而巧妙植入市场竞争机制。凭单制存在公平导向、效率导向及公平与效率兼顾等不同政策取向及模式。尽管它在公共部门需要一定的运作条件,但能广泛运用于包括食品、住房、医疗、教育、幼儿保健等具有融合特征的"福利物品"提供领域。     

Child labor legislation: effective, benign, both, or neither?

This paper explores the relationship between the state-specific child labor legislation and the decline in child labor that occurred in the US between 1880 and 1900. The existing literature that addresses this question uses a difference-in-difference estimation technique. We contribute to this literature in two ways. First, we argue that this estimation technique can produce misleading results due to (a) the possibility of multiplicity of equilibria and (b) the non-linearity of the underlying econometric model. Second, we develop an empirical strategy to identify the mechanism by which the legislation affected child labor decisions. In particular, besides establishing whether the legislation was effective or not, our analysis may determine whether the legislation constituted a benign policy or not, i.e., whether the legislation constrained the behavior of families (not benign) or whether it changed the labor market to a new equilibrium in which families voluntarily respected the law (benign).     

Materialism, status signaling, and product satisfaction

The consumer satisfaction literature has not, for the mos part, integrated individual values into the product evaluation process. Yet a comprehensive understanding of consumer satisfaction can best be attained by including both consumer and product factors. To demonstrate the usefulness of including individual values, this research focuses on one consumer value, namely, materialism. The authors empirically explore how this individual value is linked to consumers’ evaluations of products they have purchased. Using surveys, the authors collected data from a sample of college students (n=211) and a sample of adults (n=270). Across these two studies, using divergent samples and products, they find consistent evidence that materialism is negatively related to product satisfaction in product categories with high potential for status signaling, but unrelated to product satisfaction in product categories with lower potential for status signaling. The consumption goals that produce these product evaluations are empirically addressed Jeff Wang (jianfeng76@yahoo.com; PhD, City University of Hong Kong) is an assistant professor of marketing in the Faculty of Business at the City University of Hong Kong. This work was conducted when he was a doctoral student of marketing in the Eller College of Management at the University of Arizona. His research interests include social networks and consumer behavior, consumer satisfaction and well-being, materialism and consumption meanings, and consumer interests and public policy issues. His dissertation studies credit card debt as a socially embedded phenomenon and investigates how consumers leverage their interpersonal ties as they accumulate and repay their debt.
