Evaluating the multi-period efficiency of East Asia airport companies

The aim of this study is to analyze how internal operating sub-processes and annual operations of airport companies influence the overall efficiency. The multi-period Network Data Envelopment Analysis is used to evaluate the efficiencies and the efficiency changes for East Asia airport companies. The results indicate that the overall efficiencies of airport companies during a specified period of time are affected by the system efficiency and the sub-processes’ efficiencies in individual periods. Furthermore, the overall efficiency change is determined by the sub-processes’ efficiency changes. According to the operating decision analysis matrix, managers can discover the inefficient sub-processes and formulate the improvement countermeasures.     

Merger and acquisitions in South African banking: A network DEA model

Banking in South Africa is known for its small number of companies that operate as an oligopoly. This paper presents a strategic fit assessment of mergers and acquisitions (M&A) in South African banks. A network DEA (Data Envelopment Analysis) approach is adopted to compute the impact of contextual variables on several types of efficiency scores of the resulting virtual merged banks: global (merger), technical (learning), harmony (scope), and scale (size) efficiencies. The impact of contextual variables related to the origin of the bank and its type is tested by means of a set of several robust regressions to handle dependent variables bounded in 0 and 1: Tobit, Simplex, and Beta. The results reveal that bank type and origin impact virtual efficiency levels. However, the findings also show that harmony and scale effects are negligible due to the oligopolistic structure of banking in South Africa.     

专用性人力资本与三项贴水关联性研究

人力资本按专用性程度分为专用性人力资本、普通专用性人力资本和非专用性人力资本,员工的贴水可以分为收入贴水、品牌（信誉）贴水和情感贴水。通过揭示专用性人力资本和三项贴水的内在关联性,将两者进行深化匹配,在此基础上有助于给出组织运行机制的合理设计。     

工程建设施工阶段的质量控制

工程施工过程中的质量控制是工程质量控制工作中的重点,是保证工程质量的关键。工程质量的好坏,不仅与设计选型有关,而且与施工质量有关。因此,要对工程建设各个施工阶段的质量控制做到层层把关,环环紧扣,争创优质工程。     

区域经济实力的二次相对评价

提高各地区发展经济实力的有效努力程度比评价各地区经济实力更为重要。采用二次相对评价方法,可以消除由于各地区客观经济基础的不同而产生的对评价结果的影响,能够真正体现各地区在发展区域经济实力方面的主观有效努力程度。     

我国社会保障支出的地区差异分析

文章首先运用GE指数分解法,分析我国社会保障支出区域差异及贡献率;然后运用GINI系数分解法,分析社会保障各项支出对总体差异的贡献率。结果表明:三大区域总体、区域内及区域间的差异基本呈下降趋势,期间略有起伏,但区域内差异远远大于区域间差异;东部、中部和西部地区差异变动趋势不一致,且对总体差异的贡献率差别较大;社会保障各项支出的贡献率差异较大,其中社会保障补助支出成为总体差异的主体因素。文章最后对实际测算结果作进一步分析,并提出相应的政策建议。     

吉林农村金融现状与问题分析

当前吉林省同全国一样,农业和农村发展仍处在艰难的阶段,农业基础设施脆弱、农村社会事业发展滞后、城乡居民收入差距扩大的矛盾依然突出.目前,农村金融服务主体少、能力弱,农村金融市场不完善、农村金融改革不彻底,长期处于一种被抑制状态,难以满足农户和农村中小企业对信贷的需求,已成为制约农村经济发展的一个"瓶颈".吉林是一个农业大省,农村金融问题更加突出,只有找出存在的问题探索出对策,才能解决吉林省的困境,推动农村经济发展.     

基于循环经济的安徽城市效率分析

按照循环经济的"3R"原则构建了评价城市效率的指标体系,并运用数据包络分析法(DEA)对安徽省17个地级市的城市相对效率进行了定量分析,根据评价结果结合各地实际情况分析原因,对安徽省城市的发展和宏观决策均有参考价值。     

Outsourcing and firm performance nexus: An analysis using the conventional and panel double-bootstrap procedure

Industrial performance is an essential element of economic progress. In this study, we examine the impact of outsourcing on industrial performance using the firm-level data of 191 textile companies in India over the period 2000–2015. First, we follow the conventional non-parametric two-stage procedure and analyse the nexus between outsourcing and firm performance under a single-objective setting. We then test the influence of outsourcing on the performance of multiple-objective firms using reverse directional distance function scores. To address the bias in efficiency estimation and the serial correlation issue in the second-stage regression, we use truncated regression and the double-bootstrap procedure for panel data analysis. Our results show an improvement in industrial performance over the study period. Our analysis following the conventional two-stage procedure shows that the outsourcing of manufacturing activities and professional jobs contributes to industrial performance. The relation between outsourcing and firm performance essentially remains the same in a more reliable analysis using a panel double bootstrap procedure.     

养老保障制度"优化"理念分析

本文立足于养老保障制度的多层次和可持续发展目标,提出养老保障制度“新三支柱”和“八层次”优化理念,以及养老保障优化的性质界定、优化主线、优化效果、优化核心、优化目标。养老保障制度优化性质就是采取一定措施使养老保障水平“适度”和养老制度“可持续”发展。养老保障制度优化主线是养老资源的合理利用和效应最大化,也就是养老“人、财”体系的效用改进。养老保障制度优化的效果是构建一个“结构合理,功能提升,效率改进,发展持续”的养老制度体系。养老保障制度优化的核心是解决“资金平衡”和“利益均衡”。养老制度的优化标准和目标是制度的可持续发展,具体表现为养老制度的优化与风险控制、国民财富分配、人口结构、居民收入水平、社会文化等要素契合协调发展。在此基础上,提出优化养老方式整体效率、优化多层次抗风险、优化多责任破解时代难题、优化多元个人生命周期等政策建议。
