建设项目财务评价指标--投资回收期浅析

投资回收期是建设项目可行性重要财务评价指标之一，投资回收期可分为静态投资回收期、动态投资回收期、静态追加投资回收期、动态追加投资回收期。分析四种计算方法的利弊和适用条件，并在此基础上探讨投资回收期计算方法的选择及应用，建议以动态投资回收期及动态追加投资回收期为主，作为投资回收期评标指标。     

汽车节油的油耗经济效益指标分析

由于诸多因素影响,吉林省汽车油耗一直处于全国下游水平。以1988年吉林省全民运输企业载货汽车汽油油耗为例,为8.1升/百人公里,柴油油耗为5.6升/百人公里,与全国平均油耗水平相比,分别高出0.3和0.7升。为了进一步提高吉林省汽车运输油耗水平,促进汽车运输企业的经济发展,并进一步带动吉林省汽车油耗水平提高。1991年经吉林省科委立项,由吉林省交通厅,吉林省科技情报研究所,吉林省运输管理局,吉林省交通科学研究所共同参加,进行“吉林省汽车油耗水平

Diversification,restructuring and economic performance

During the 198Os, many conglomerates and other diversified firms reduced their diversification by refocusing on their core businesses. This paper provides an economic explanation for this phenomenon and empirically tests the hypotheses that emerge from the analysis. It is shown that refocusing is associated ex post with Profitability improvements.     

Ownership structure and economic performance in the largest european companies

The paper examines the impact of ownership structure on company economic performance in 435 of the largest European companies. Controlling for industry, capital structure and nation effects we find a positive effect of ownership concentration on shareholder value (market‐to‐book value of equity) and profitability (asset returns), but the effect levels off for high ownership shares. Furthermore we propose and support the hypothesis that the identity of large owners—family, bank, institutional investor, government, and other companies—has important implications for corporate strategy and performance. For example, compared to other owner identities, financial investor ownership is found to be associated with higher shareholder value and profitability, but lower sales growth. The effect of ownership concentration is also found to depend on owner identity. Copyright © 2000 John Wiley & Sons, Ltd.     

工程项目绩效评价中项目难度系数的确定

项目难度系数的确定是工程项目进行项目绩效定量评价的关键环节之一,尤其对多项目部的绩效定量评价更重要。依据项目难度系数的影响因素,确定每一影响因素的权重和项目因素单位分数。通过层次分析法和直观判断法综合对工程项目评价指标进行权重分析,提出了两种打分的方案,即对工程数量、投资额及项目难度等因素进行分类打分和根据单位数量及单价来确定分数,然后结合两种方法的结果来确定项目难度系数,并通过实验来确定项目难度系数计算方法的合理有效性。     

模糊综合评判在发动机性能评估中的应用

发动机工作状态的好坏能通过发动机的性能参数反映出来,利用模糊综合评判法对测得参数的相关数据进行处理,然后对被测发动机性能做出综合评估,可提高评判结果的可信度。笔者结合发动机性能测试与评估系统的设计,介绍了模糊综合评判法的原理及其数学模型的建立,阐述了该模型在发动机性能测试与评估系统中的应用,并给出了该测试评估系统的硬件组成以及实现测试评估的软件表述和模块构成。     

The effect of spatial variables on the economic and environmental performance of bioenergy production chains

The aim of this paper is to understand the impacts of spatial variables on the performance of bioenergy production chains (BPCs). Even though the strong debates continue on the use of first generation biomass for bioenergy production, many countries continue to utilize it as an alternative energy source. Several studies have been carried out on biomass transformation efficiency, on environmental impacts of using crop in biofuel production, and on its negative effects on increasing food prices. However, less attention has been paid to the role played by the spatial variables on the performance measures of BPCs.In this paper, we analyse how three spatial variables, i.e. cultivation area size, land dispersion, and accessibility to cultivation areas, can affect the performance of energy-balanced BPC, which produces its own electric and thermal energy demand. The chain is represented as a network of processes, where all inputs and outputs are geographically referred and analysed in a theoretical case example. We propose an enterprise input-output (EIO) model, which can be used as an accounting tool to compute the main materials and energy flows-related costs and as a planning tool to evaluate the chain performance in different scenarios. Finally, the proposed model is applied to an actual case study, to investigate the opportunity to establish a sunflower-based BPC in Apulia region (Italy) and to assess its performance.Results show that higher land dispersion degree and less area accessibility levels reduce the economic and environmental performance of the BPCs. The construction of the energy-balanced chain reduces the negative environmental impacts caused by fossil energy use in the processes of the BPC. Managerial implications can also be obtained from actual case study about the biodiesel plant location decisions.
