AN EVALUATION OF PROCESS‐ORIENTED SUPPLY CHAIN MANAGEMENT FRAMEWORKS

Supply chain management (SCM) is implemented by integrating corporate functions using business processes within and across companies. Several process‐oriented frameworks for SCM have been proposed but only two of these provide sufficient detail to enable implementation. We evaluate the Supply‐Chain Operations Reference (SCOR) framework and The Global Supply Chain Forum (GSCF) framework using four criteria and identify their relative strengths and weaknesses.     

Demand‐side housing policy in Costa Rica: a response to the housing deficit

The purpose of this study was to establish what the housing needs of Costa Rica are and to assess what policies have been implemented to respond to their housing deficit. In order to answer these questions, a combined methodology consisting of primary and secondary data was used. Using open‐ended questions and a topic schedule, face‐to‐face interviews with Costa Rican housing authorities were conducted at the interviewee's work place in Costa Rica in May 2003. The most recent secondary data available in the country was used to compute the housing deficit and to study the effects of demographics on current housing needs. Sources of the secondary data were the Costa Rica Ministry of Housing and Human Settlements, and the National Institute of Statistics and Census. The Costa Rican government has made great progress in reforming the housing finance system in order to meet the housing demand of its citizens. In 2002, Costa Rica had a 75.6% home ownership rate. Yet, even in light of the housing system's current success, many social, economic and political barriers threaten to undermine its accomplishments and the peoples’ ability to obtain safe and affordable housing. The paper considers the strengths and weaknesses of the current housing finance system as well as the government strategies for addressing difficulties.     

行政许可法打造法治政府

通过对新颁布的《行政许可法》的梳理和分析，认为《行政许可法》在有限政府、程序政府、责任政府等方面建立了许多具有突破意义的制度和新的规定，这些制度的建立和新的规定的实施，必将为我国建立法治化政府，进而建设社会主义的法治化国家，带来深远意义的影响。     

基于核心能力理论的企业集群边界问题研究

随着企业集群的迅猛发展,集群组织边界的识别与界定已成为实现企业集群有效治理的一个核心问题。以企业核心能力理论为基础,通过分析企业集群生产与交易活动中的企业能力、资产专有性、不确定性及交易频率等4个维度,对企业集群的组织边界进行了识别和界定,以期对企业集群的治理实践奠定必要的理论基础。     

企业网络的效率边界研究述评

企业网络是一种既不同于企业也不同于市场的中介性组织形式。企业网络的出现是企业追求效率的结果,同时,它的出现也对现代企业理论关于企业与市场的两分法提出了挑战。对此,理论界纷纷从不同视角对这一新型组织形式展开了讨论,提出了疑问,如什么是企业网络、企业网络存在的价值、企业网络的效率边界应该多大等。本文将对目前学术界关于这些问题的研究现状作一简述。     

基于交易费用理论的企业边界纵向一体化研究

交易费用理论认为，企业的最优边界在市场费用等于企业协调成本那一点，交易费用中的企业规模实质上是企业的纵向规模即纵向边界，企业纵向规模的扩张主要通过纵向一体化来实现。虽然纵向一体化能够有效地削弱人的机会主义和有限理性，克服不确定性，降低交易成本，但它并不必然是企业发展的一种好办法，企业发展到一定阶段，纵向分拆策略是有效的。企业的纵向边界呈现扩张与收缩交互进行的局面。     

现代契约经济学的企业边界决定理论:比较和评述

包括Klein的自我履约机制,Grossman, Hart and Moore的资产配置理论和Rajan ＆ Zingales的＂进入权＂理论在内的现代契约理论在不完全契约的框架下,通过引入可占用准租、资产剩余控制权和进入权等重要概念,较好地解释了企业边界决定问题,但却没有得出最大化准租的企业边界是最佳的企业边界这一应有的结论.最大化准租是交易双方多重复合交易的成果,在这一最终目的指引下,契约安排的不同形式及其所决定的企业边界的多样性,为现实中的企业调整边界和实施战略管理提供了理论依据.     

Simulation driven inferences for multiply imputed longitudinal datasets*

In this article, we demonstrate by simulations that rich imputation models for incomplete longitudinal datasets produce more calibrated estimates in terms of reduced bias and higher coverage rates without duly deflating the efficiency. We argue that the use of supplementary variables that are thought to be potential causes or correlates of missingness or outcomes in the imputation process may lead to better inferential results in comparison to simpler imputation models. The liberal use of these variables is recommended as opposed to the conservative strategy.     

Linking Public Investment to Private Investment. The Case of Spanish Regions

Public investment constitutes one of the main instruments of regional policies. The existence of a direct link between infrastructure and regional income per capita is usually accepted. Literature also describes a positive effect of public investment on private capital accumulation. This paper seeks to provide new empirical evidence on this latter relationship for the case of Spanish regions over the period 1965–1997 using panel data methodology. The results show a positive effect of productive and social public investment (especially in education) on private investment. The spillover effects generated by the productive infrastructures located in other regions do not seem to encourage the private investment in neighbouring regions. Public consumption and interest rate exert a negative influence on private capital accumulation. These results are robust to changes in the econometric specification.     

企业边界、企业扩展与企业成长的比较分析——对企业成长理论的重新解读

企业的边界理论很好地说明了企业与市场的替代关系，但却对现实中企业复杂的扩展行为与成长现象解释乏力。其实企业的边界、扩展与成长，每个概念都有其独特的内涵，并都代表着一种研究视角与理论假定。本文通过对3个概念的比较分析，对企业的主体性、企业演化成长的动力、阻力与经济效率等一些基本问题进行了梳理与研究，以期能够对企业成长理论有一个较为全面的阐述。
