Monthly wood supply behavior of associated forest owners in Austria—Insights from the analysis of a micro-econometric panel

This paper examines the wood supply from non-industrial private forest owners in Austria. The main novelty of this study is threefold. First, the underlying dataset is based on monthly wood supply. This enables an analysis of seasonal supply behavior, which is found to be different in relation to the size of the forestland. Second, it represents an original study with a dataset from a Central European country whose forest owners are apparently much more fragmented than their Scandinavian or North American counterparts. And third, the study introduces a windfall variable that effectively corrects for a market-relevant storm event. With respect to methodology, a random effects Tobit model is applied. Additionally, a Chamberlain-like term is included in the regression to deal with a possible bias generated through the correlation of regressors and unobserved heterogeneity.     

Toward Greater Validation of Supply Chain Management Theory and Concepts: The Roles of Research Replication and Meta‐Analysis

Although researchers have been working for over three decades to identify, construct, and test the critical concepts and theories that comprise the supply chain management (SCM) discipline, the field’s theoretical basis has yet to be thoroughly vetted through repetitive, rigorous study. Emerging theories in SCM offer great explanatory potential, but if they are to stand the tests of time, place, and reason, research findings must be accumulated and synthesized. For the field to prosper, we advocate the execution of multiple studies that replicate findings across contexts while simultaneously encompassing relevant theoretical extensions. Furthermore, as SCM research streams mature, scholars should then employ meta‐analytic techniques to gain consensus across studies, such that findings can be more confidently extolled to both academic and practitioner constituencies. In this article, we evaluate the progress of replication and meta‐analysis to date within the SCM field and provide some prospects for thematic research that could perpetuate accelerated validation.

Corporate Portals for Supply Chain Collaboration

ABSTRACT

This article reviews the technological capabilities offered by the portal industry's key software vendors to support inter-firm design collaboration and supply chain integration. An analysis of the technology coverage and gaps is presented, with a focus on the opportunities available for portal software improvement. Challenges for collaboration and supply chain software, including security, external access and capabilities, bandwidth and communication standards are discussed, particularly in context with the demands of portal software users. As well, a picture of the current and future state of the marketplace is developed from an analysis of the market position and product direction of a selection of eight enterprise portal vendors.     

水果“进京”流通渠道优化模型的研究

Customer Relationship Management in Electronic Markets

Abstract

Customer relationship management, or CRM, has found increased attention in both the academic and managerial worlds of marketing in recent years. While the Internet has greatly enabled the application of CRM in fostering loyal customers, the preliminary results on the effectiveness and efficiency of technology-based CRM has been far from discouraging. The authors identify various contentious issues behind the various key concepts of relationship management and identify several areas that deserve closer academic scrutiny and managerial inspection. The paper also comments on the extent to which Internet technology can bring about closer relationships with a firm's customers.

基于信息共享的供应链定价策略及利润增值研究

基于单一制造商和单一零售商构成的供应链系统,在非线性市场需求的前提下,应用博弈理论对供应链系统的定价策略进行了分析,分别得出信息共享时的博弈均衡解和信息不共享时的博弈均衡解;进一步分析了信息共享程度的大小与批发价、零售价以及双方利润之间的关系,得出信息共享程度越高,制造商和零售商的利润越大,信息共享实现了帕累托改进。最后,通过实例对结论进行了验证。
