建筑工程无标底招标理论与实践

随着中国建筑业管理体制改革的不断深化，招投标制度在中国得以推广应用，但在招投标机制方面还存在不足，有待完善。文章通过无标底招投标的博弈论基础，分析了无标底招标的意义和作用，同时对无标底招标的实施提出了一些相应的措施和建议，最后指出，随着中国加入WTO，与国际接轨，推广无标底招投标方法是我国建筑业招投标制度改革的当务之急。     

Unlocking the potential of advanced manufacturing technologies

This research examines whether investments in advanced manufacturing technologies (AMTs) such as flexible manufacturing systems (FMS), computer aided design (CAD), computer aided manufacturing (CAM), robotics, etc., are more likely to lead to improved performance if they are supported by improvements in the manufacturing infrastructure of the company. This question is evaluated using data gathered from 202 manufacturing plants chosen from industries generally considered to have relatively high investments in technology.Multiple item scales are developed and adapted from sources in the literature to measure investments in technology, infrastructure, and the performance of the plant. Evidence supporting the reliability and validity of these scales is provided. Hierarchical regression is used to analyze the relationship between technology, infrastructure, and performance. The results suggest that there is an important interaction between the adoption of advanced manufacturing technologies and investments in infrastructure. Firms that invest in both AMTs and infrastructure perform better than firms which only invest in one or the other. Separate analyses on sub-samples of firms with the highest and lowest investments in AMTs show that infrastructural investments have a stronger relationship with performance in the high investment group. Thus, the data indicate that infrastructural investments provide a key to unlocking the potential of advanced manufacturing technologies.

学习陈云同志的经济思想提高驾驭宏观经济工作的能力

在陈云同志诞辰100周年的时刻,我们缅怀这位伟大的无产阶级革命家、政治家,杰出的马克思主义者,党和国家久经考验的卓越领导人,同时回忆起陈云同志作为我国社会主义经济建设的开创者和奠基者之一,一生为社会主义经济建设作出的重要贡献。陈云同志在领导新中国经济建设的实践中,提出了许多科学的经济观点和思想,不仅为促进经济建设的健康发展,探索中国特色的社会主义建设道路,推进经济体制改革和对外开放,发挥了非常重要的作用,而且对我国当前落实科学发展观,促进经济社会协调发展,也具有深远的指导意义。陈云同志经常讲,工作要做好,一定要实…     

Group decision-making: Head-count versus intensity of preference

This paper puts forth a framework for reshaping the group decision-making process. The proposed framework extends from the usual one-issue-at-a-time decision-making to one that involves several related issues simultaneously. Weaknesses of the traditional majority voting mechanism are first identified, and then a different voting method that takes each individual voter's sentiment into account is discussed. Specifically, a decision-maker is asked to express his/her intensity of preference for the issues encountered. Three hierarchical structures—benefits, costs, and risks—are developed to evaluate the alternatives. Due to the nature of pairwise comparisons and synthesis, the proposed method is amenable to consensus building and has higher reliability and consistency. It can be used for candidate selection, e.g. governmental election, when a large population is involved. It is also effective for resource allocation and prioritization when a small group or business is concerned. We believe the proposed approach has potential for resolving deficiencies of the conventional voting mechanism, and can be applied to many real-world problems. Its implementation on the Internet is also discussed.     

Identification and estimation of econometric models with group interactions,contextual factors and fixed effects

This paper considers identification and estimation of structural interaction effects in a social interaction model. The model allows unobservables in the group structure, which may be correlated with included regressors. We show that both the endogenous and exogenous interaction effects can be identified if there are sufficient variations in group sizes. We consider the estimation of the model by the conditional maximum likelihood and instrumental variables methods. For the case with large group sizes, the possible identification can be weak in the sense that the estimates converge in distribution at low rates.     

规划理论二分法中的本体理论和程序理论

规划的本体理论与程序理论是规划理论二分法中最为显著的一组二元对立.首先界定了规划本体与规划程序之间的差异,然后通过辨析三组规划理论,即规划中的理论与规划的理论、系统理论与理性理论、导向型理论与交往型理论,深入探讨了规划的本体理论与程序理论之间的联系与区别,以及它们对规划方法和实践的影响.     

Implications of variant efficiency measures for policy evaluations in UK higher education

Policy goals in UK higher education encourage the publicly funded universities to become more-specialised and larger in size without compromising output quality. Efficiency gains are expected to flow from this increased specialisation in accordance with universities’ comparative research and teaching strengths. Mergers to reap further gains from economies of scale are also being actively encouraged. Given this scenario, the paper investigates whether best-practice efficiency measurement based on data envelopment analysis (DEA) provides empirical support for the current policy goals. It also assesses whether such support is dependent on the specific type of efficiency measure used in the DEA modelling. This assessment finds that a selection of (nine) commonly used, variant efficiency measures generally support the current policy goals. The paper also uses the principal-agent framework to explore the issues involved in using computed DEA-based efficiency scores for policy evaluations and possible funding guidance in UK higher education. This highlights empirically how policy-makers and universities can have very different preferences about which efficiency measure is to be used for policy evaluations and possible funding guidance.
