我国国有企业改革:历程、思路与展望

2008年是改革开放30周年,同时国有企业改革也走过了30年.总结我国国有企业改革的历程,反思改革过程中理论思路,发现主导我国改革的实际上是对在所有权和经营权中,何者是决定企业效率的决定因素的理解上.我国的改革在开始的阶段是以不改变所有权基础上的企业经营控制权的改革为主导,而在后一阶段则是以所有权改革来推动企业经营控制权的改革为主导的.     

中外高校机构编制管理的比较及启示

我国高校机构编制管理缺乏有力的外部监督和内部约束;而以美国为代表的国外高校则在“行政-学术”二元权力架构的安排、管理机构的设置、人员编制的分类与控制等方面形成了一整套科学的做法。借鉴其经验,应通过国家或地方行政立法来规范高校机构编制管理,将机构编制管理绩效纳入对高校的考核范围,要在精简机构的同时建立健全高校的学术权力机构,各地教育行政部门也要建立起一套完善的实施监管的技术性程序。     

控制火电厂二氧化硫排放的有效途径——排污权交易

目前,我国工业二氧化硫排放量中有42%是火电厂排放的,因此高效控制火电厂的二氧化硫排放是提高空气质量的主要途径。美国利用排污权交易治理火电厂的二氧化硫排放取得了巨大的成功,不仅二氧化硫排放量大幅下降,而且排污权交易也被证明是成本最低的方法。借鉴美国的经验,可以为我国治理火电厂二氧化硫排放提供高效途径。

浅论可持续竞争力的构成要素

可持续竞争力具有持续性、难以模仿性、开放性和动态性等特征.可持续竞争力是一个系统,它由四个要素构成,包括战略性资源、动态协调的组织能力、系统的规划能力以及持续的学习能力.而且这四个要素彼此影响,相互作用.     

省级节能发电调度试点实践及推广建议

实施节能发电调度是电力行业落实科学发展观的重要举措。介绍了河南、四川两省3年来开展节能发电调度试点工作的情况,总结了开展“上大压小”和节能发电调度在优化电源结构、降低煤耗水平及污染物排放方面取得的显著成果,针对试点中反映出来的问题,对今后进一步开展节能发电调度、推广试点经验,就市场机制建设、可再生能源项目建设、经济补偿政策和电网建设等方面提出了建议。     

The heterogeneous relationship between board social ties and corporate environmental responsibility in an emerging economy

Firms in emerging economies are faced with multiple, incompatible institutional forces in their environmental activities. Which of these forces will be dominant and instantiated within an organization is partly determined by the social relationships that a firm maintains with external actors. This paper investigates the relationship between board social ties and the level of environmental responsibility undertaken by firms in China, an emerging economy, by categorizing board social ties into three types in terms of the three isomorphic forces in the institutional field (coercive, normative and mimetic). Drawing on institutional and agency theories, using a sample of listed firms in environmentally sensitive industries, and a generalized least squares regression method, the results provide empirical evidence that ties that are linked to coercive and normative forces (i.e., political organizations and universities) are related to a higher level of environmental responsibility; however, those that are linked to mimetic forces (i.e., industrial peers) have a negative association with environmental responsibility, which is mitigated by CEO power. These findings suggest that the heterogeneous effects of board social ties on environmental responsibilities experienced by firms in a context of environmentalism are at an early stage.     

安徽省主要城市工业用电效率及影响因素分析--基于DEA及Tobit两阶段模型

随着节约型社会的构建,安徽省不断加大对能源使用效率的监督和管理力度,为了明确安徽省近年来工业用电效率及其影响因素,采用数据包络及托宾回归模型对2004-2011年安徽省17个主要城市工业用电效率进行评价和分析。研究结果表明：（1）自2004年以来,安徽省主要城市工业用电效率一直处在上升阶段,但是与最优水平仍存在一定差距,同时还发现工业增加值与用电效率之间并不存在显著关系;（2）工业经济发达城市唯有依靠技术效率来提升用电效率,工业经济欠发达城市则需通过规模经济来实现用电效率的改善。（3）对外开放水平、节电意识、科技水平以及政府支出对工业用电效率有正向影响。     

基于全寿命周期分析的电力设备费用模型

针对我国供电企业的实际情况,将电力设备费用分为一次投资费用和运行维护费用两部分,建立了电力设备全寿命周期费用定量模型。针对一次投资费用的特点,建立了基于时间分摊的一次投资费用模型;针对运行维护费用长期发生的特点,建立了基于灰色关联度确定分布类型的运行维护费用模型。同时,将两个费用模型综合考虑,建立了供电企业电力设备全寿命周期费用模型,据此可计算电力设备全寿命周期最小费用和最佳使用寿命。最后,以某变电站综合自动化项目为例,验证了该模型的有效性。     

Small is beautiful: Implications of reliability and statistical power for testing the efficacy of HR interventions

The development of optimal human resource practices is often contingent on the accurate statistical testing of potential interventions. Testing the efficacy of HR interventions can be enhanced by taking additional measures to improve statistical power, but the traditional means of increasing power through sample size are often beyond the cost and ability of HR professionals to pursue. This article, therefore, focuses on measurement procedures as an alternative way to increase statistical power for detecting HR intervention effects. Selection of reliable and appropriate measures and subsequent instrumentation are examined as efficacious and cost‐beneficial techniques that can be employed during the planning and designing stage of a study for augmenting statistical power to optimize business decision making. © 2012 Wiley Periodicals, Inc.
