模块化组织与大型企业基因重组

随着信息技术的不断应用和发展，大型企业尤其是垂直一体化企业越来越难以生存，取而代之的是精益的模块化组织。本文认为模块化组织是大型企业在其内部市场对“基因”能力要素进行重组的必然结果。大型企业通过对“基因”能力要素进行重组，一方面扩展了其能力边界，另一方面也培育了一种新型的组织形态即模块化组织。模块化组织不但降低了大型企业内部的协调成本和外部的交易成本，也为大型企业的未来组织设计提供了新思路和新挑战。     

股权制衡与公司经营业绩

本文使用A股公司1992~2001年的数据,从经营业绩方面比较了股权制衡公司与“一股独大”公司,发现前者显著差于后者。因此,“一股独大”并非坏事,用股权制衡来替代“一股独大”以改善“一股独大”公司的经营业绩的思路未必奏效。这很可能正是中国制度背景的表现所在。     

基于频域指标的数字控制器直接设计法

本文根据 Ragazzini 直接设计法的思想,综合应用最少拍设计法,零极点综合法及大林算法中的处理方法,提出一种基于频域指标要求的数字控制系统直接设计法。这样设计的系统具有适应能力强、无振铃现象等优点。     

山东省生态用地变化及驱动因素影响评价

［目的］研究第二次土地利用现状调查以来山东省生态用地变化特点及驱动因素,评价各类驱动因素对生态用地的影响程度,为科学编制区域空间规划,保护和合理利用生态用地提供参考。［方法］文章构建了全省生态用地转移矩阵,归纳了影响生态因素变化的主要驱动因素,提出了驱动力指数计算方法,定量分析和比对了各驱动因素对生态用地的影响。［结果］2009—2017年生态用地共计转出2048万hm2,占生态用地总面积的472%; 转入316万hm2,占生态用地总面积的072%。8年来全省生态用地净减少1732万hm2,占2009年生态用地总面积的400%。生态用地的流向以耕地最多,向城镇村及工矿用地流出次之,向设施农用地的流出也有较大面积。［结论］（1）在影响生态用地变化的六大驱动因素中,耕地开发和城镇村工矿占用的驱动力指数最高,非耕农业占用对生态用地的变化有一定影响。（2）六大因素中城镇村工矿占用对当地生态环境的破坏力最强。     

我国金融与房地产行业体系性风险度量：基于SRISK方法

次贷危机引发的全球金融危机凸显了体系性风险的巨大杀伤力,使得各国监管当局加强以监控体系性风险为核心的宏观审慎监管。本文适当改进SRISK方法并测度我国2006年至2016年间55家金融机构和119家房地产公司的体系性风险大小,对我国金融体系及各部分的体系性风险及影响因素进行了静态分析和动态分析。本文认为我国金融体系当前的风险水平较高,建议监管当局加强对相应金融机构的监管,并建议各机构降低杠杆率,控制自身的体系性风险。     

Dynamic efficiencies of the 1997 Boeing‐McDonnell Douglas merger

We evaluate the welfare effects of the 1997 Boeing‐McDonnell Douglas merger in the medium‐sized, wide‐body aircraft industry. We find that the merger led to lower prices. To explain the price drop, we develop a dynamic oligopoly game with learning‐by‐doing. We quantify the welfare effects of the merger by incorporating both increased market power and merger efficiencies from accelerated learning‐by‐doing. Our dynamic analysis indicates that net consumer surplus increased by as much as $5.14 billion, whereas a static model ignoring efficiencies of learning‐by‐doing predicts a $0.92 billion loss.     

我国都市圈的空间格局和发展方向

都市圈是我国区域经济发展的主要形态.我国目前已形成了27个都市圈,空间格局呈现东南密、西北疏、沿海和沿江分布的特点,发展阶段由东向西逐步递减,与我国重大战略存在空间一致性.新时期,要以都市圈为支撑构建现代区域发展体系,着重在重大国家战略外培育一批都市圈,提升黄河流域和东北地区都市圈发展水平,促进成熟期都市圈向城市群转变,加快都市圈融入新发展格局,最终形成"两横三纵"的都市圈空间格局.     

Do You See What I See? A Simulation Analysis of Order Bundling within a Transparent User Network in Geographic Space

The Physical Internet (PI) concept presents a radical change with the aim to revert the unsustainable practices that are used for transporting goods. It identifies dedicated freight flows and transforms them into transparent open logistics networks which can be accessed by other users, such as shippers and carriers. In this paper, we test the universal network openness in which the users can tap into the PI network and place orders that will be assigned to the nearest available transport service and consequently delivered to the order sender. The objective of our paper is to investigate the impact of inserting extra service points into existing dedicated freight flows of a service‐driven company. We simulate different transparency levels and routings to new pickup locations and evaluate the impact in terms of altered lead times, covered distances, and fill rates. The novel aspects presented herein are (1) deliveries based on decentralized location detection of the nearest order sender, (2) dynamically changing speed parameters of agents within specific geographic clusters based on their geo‐locations in order to account for congestion levels, (3) more realistic routing strategies that consider the urban layout, and (4) transparent querying of nearest agents in space and time that meet specific conditions such as current ongoing processes, available capacity, and position. Finally, we identify the impact from a general/holistic perspective that emerges once extra orders are assigned to the service‐driven company's fleet.     

Understanding the institutional challenges and impacts of higher education reforms in Indonesia

ABSTRACT

This paper contributes to the academic literature on policy-making at the global level by empirically showing the nature and institutional challenges of higher education reforms under NPM principles. The authors explain the key strategies adopted by Indonesia’s government and the problems it faced in reforming its higher education system. The overall result was negative. The Indonesian reforms will not bring about meaningful outcomes unless the existing institutions, and the environment in which they operate, are also reformed.     

旅游院校应建立具有旅游特色的英语教学体系

论述了中国加入WTO的新形势下，旅游院校的英语课教学应走出一条创新的路子，英语教学应贯穿于整个大学教育的始终，同时也强调实用英语的重要性．英语教学目标应分为阶段性目标和终极性目标两种．只有这样才能培养出具有国际竞争能力的旅游专业人才。
