PTE,innovation capital and firm value interactions in the biotech medical industry

Unlike previous studies which only focus on the main effect between IC and FV, this research includes PTE with the gap of resource-based view. IC is a key element in creating a competitive advantage, as it has a great influence on FV. A company may put relatively less into IC if it demonstrates higher efficiency. However, previous studies have neglected the fact that relative efficiency and IC affect FV and stock returns directly and indirectly. The research period was from 2006 to 2010 and the main research methods include HRA and DEA. The main research findings include the following. (1) There is a space for improvement in terms of the total technical efficiency. (2) PTE has a significant moderating effect between IC and FV. (3) IC and PTE have a significant influence on FV. (4) Apart from PTE and stock returns, IC and FV show significant differences within the sub-industry.     

基于DEA模型的酒店经营效率分析

运用DEA方法对酒店在运营中效益及成本之间的相对有效性进行了分析,通过对酒店投入-产出比的C2R模型的定量计算,有效辨别出酒店不同月份运营的DEA有效及非DEA状态,并据此分别给出了酒店未来投入-产出的调整方向,为酒店管理者的决策提供理论依据。     

钢铁行业相对效率的DEA实证分析

通过应用数据包络分析法(DEA)对2007年中国A股上市公司11家代表性钢铁公司的相对效率进行实证分析,结果表明:8家公司的规模效益不变,本钢板材规模效益递增,规模效益递减的只有2家公司。根据经济学上的3阶段生产理论,最佳的生产阶段应该在规模效益递减阶段。我国钢铁行业处于经济学上的最佳生产阶段的公司不多,还不到样本总数的20%,而处于不变规模效益的公司则占到样本总数的70%以上,说明我国钢铁行业还有很大的发展潜力。     

基于AHP的含偏好DEA物流战略伙伴选择模型研究

物流战略伙伴的评价和选择是一个非常复杂的过程。基于AHP的含偏好DEA物流战略伴选择模型,将物流运作成本和评价指标分别作为模型的输入、输出变量,考虑到了工商企业对物流企业的输出指标的偏好。文章还对输出变量进行了综合处理,使模型更具有实用性和可操作性。     

基于DEA的我国装备制造企业自主创新能力综合评价

装备制造业是任何一个发达工业体系的中枢,在经济成长和新型工业化过程中发挥着极为重要的作用。对我国装备制造企业自主创新能力的影响因素进行深入分析,在此基础上构建装备制造企业自主创新能力评价的指标体系;运用DEA理论,引入基于输入的C2R模型和单纯评价技术有效的BC2模型,从定性和定量相结合的视角,分两阶段对装备制造企业自主创新能力进行综合评价。     

我国农村商业银行效率及其影响因素分析

本文运用数据包络分析法(DEA)对13家农村商业银行2011年的截面数据进行分析,得出各农村商业银行运营的综合效率值,并运用多元回归分析法分析了影响农村商业银行效率的六大因素。研究表明,农村商业银行的创新能力和经营管理能力是影响效率的关键,非利息收入与效率成正比,资产费用率与效率成反比,而资产规模、存贷比、前十名股东持股比例以及营业范围对效率的影响均不显著。     

基于DEA的高速公路上市公司股权融资效率分析

从融资效率角度出发,将数据包络分析法(DEA)引入到高速公路上市公司股权融资效率的分析评价。实证表明,我国高速公路上市公司股权融资效率尚较低。近期,应从改革股权融资规模、股权集中度等输入指标方面来提高其股权融资效率。     

中国物流业效率提升是否有路径显现？——基于省级数据的定性比较分析

伴随着经济的发展、政策的促进,中国物流整体效率和各省级物流效率显著提升。以30个省级数据为样本,基于数据包络分析方法计算各省级物流业效率,应用组态思维的定性比较分析方法研究影响物流业效率提升的因素,探讨这些因素作用于中国物流业效率的因果复杂机制和路径。结果发现：(1)2015年以来的三年中,中国物流业发展形成两条高效率路径。其中管理开放型路径覆盖率较高,物流企业经营管理水平和区域的开放程度是物流业效率提升的核心因素;科技创新型路径覆盖案例较少,R&D投入、经济环境或开放程度是这条路径的核心要素。(2)符合非对称性特征,非高效率路径和高效率路径不具有对称性,覆盖率较高的一条非高效率路径中,非高的GDP和政府支持是导致物流业非高效率的核心因素,称之为政策依赖型路径。     

我国商业银行效率研究述评

作为金融中介机构的商业银行在经济运行中占有独特的地位,商业银行效率的研究不仅影响银行自身的盈利能力,对于金融体系的功能发挥也具有重要意义。本文以商业银行效率的结构基础、测度方法、实证检验、影响因素,以及外资银行进入对我国商业银行效率的影响为线索,总结评析国内外学者对我国商业银行效率的已有研究成果,并提出我国商业银行效率研究中存在的不足和未来有待于深入研究的问题。     

New Zealand Bank Mergers and Efficiency Gains

ABSTRACT

This paper uses accounting ratios and DEA (Data Envelopment Analysis) to explore the efficiency impacts of 6 bank mergers in New Zealand between 1989 and 1998. The paper is the first reported application of DEA to the New Zealand banking sector, and its methodology is based around that used by Avkiran in his study published in the Journal of Banking and Finance in 1999 (Avkiran, 1999b).

Consistent with earlier research, acquiring banks were found to be generally larger than their targets, although they were not consistently more efficient. In a majority of cases the merger led to an increase in efficiency, consistent with a trend observed for the banking sector as a whole. No clear conclusions could be drawn on possible public benefits from the mergers.     

Measuring the road safety performance of Iranian provinces: a double-frontier DEA model and evidential reasoning approach

Abstract

Road traffic accidents are critical public issue in developing countries, and they annually waste a significant amount of Gross Domestic Product (GDP). In order to urgently consider how this problem is related to the current policies, a proper safety evaluation of regional programmes in crash reduction is fundamental to the governments. The current research aims to employ a double-frontier Data Envelopment Analysis (DEA) model to assess the productivity of Iranian regional safety programmes in reducing the number of road fatalities. The safety efficiencies of Iranian provinces are simultaneously estimated using the double frontier DEA to reflect both the optimistic and pessimistic points of view. Then, the Evidential Reasoning (ER) approach is applied to aggregate the obtained efficiency values. These provinces are ranked based on the data panel for 2014–2016. Finally, a double-frontier Malmquist productivity index (MPI) is used to comprehensively measure the safety performance of Iranian roads over a period of time.

How do managers decide on internationalization processes? The role of organizational slack and performance feedback

This study draws on the behavioral theory of the firm to the postulate relationships between organizational slack and performance aspirations, and internationalization processes. Based on longitudinal data (2000–2008) from 772 publicly listed firms in Taiwan, the findings indicate that organizational slack significantly influences the internationalization processes. Specifically, firms with high organizational slack that have performance that falls below aspirations managers are more likely to exhibit (1) a rapid pace, (2) a wider scope, and (3) an irregular rhythm in their internationalization processes. In addition, we observed an interaction effect between performance feedback and different levels of slack on the internationalization processes.
