中国上市公司治理评价与指数研究--基于中国1149家上市公司的研究(2004年)

本文以中国上市公司公开信息为依据,基于2004年的样本,从中国公司治理指数及其所涉及的六个维度控股股东治理指数、董事会治理指数、监事会治理指数、经理层治理指数、信息披露指数、利益相关者治理指数进行比较研究,总结了中国上市公司的治理特征和年度差异.2004年公司治理状况较之2003年有较大改善,公司治理对公司绩效产生了积极作用,良好的公司治理有利于提高信息披露质量,并有利于保护利益相关者权益.本文对公司治理评价与指数未来研究提出了规划.     

圈闭地质评价中模糊数学综合评判法的优势

圈闭地质评价是进行油气资源评价的核心工作。为了克服常规含油气性及其优劣程度评价过程中许多定性因素带来的诸多不便,模糊数学综合评判法把“亦此亦彼”中间过度的模糊概念用数学方法来处理,并对圈闭含油气性及其优劣程度进行定量分析评价,充分体现了模糊数学综合评判法在圈闭地质评价中的优势所在。     

输油管道热力计算及程序设计

评价埋地热油管道的的热工状况,首要的问题是计算管道周围土壤的非稳态温度场。针对埋地热油管道的一般形式,以二维非稳定传热方程来描述输油管道的传热过程,建立了计算温度场的计算模型,在边界条件中充分考虑了地面温度的变化以及管径等参数对管路温降的影响。采用有限差分数值理论对温度场进行了计算,并由此求得了热油管道的有关热工参数。通过实例分析表明了计算方法和计算程序具有一定的实际参考价值。     

Gasoline Cost and Hedonic Price Indexes of U.S. Used Cars for 1970–1983 A Note

Hedonic price indexes are estimated for U.S. used passenger cars for 1970–1983. A few notions of indexes that differ in the treatments of the expected present value of gasoline cost for driving a car over its remaining life are considered. Their relationships are obtained theoretically and examined empirically. Our indexes also are compared with the Consumer Price Index.     

Learning strategies of workers in the knowledge-creating company

This study presents a critical examination of Nonaka and Takeuchi's theory about knowledge-creating companies (1995), taken as one example of contemporary management theories concerning innovation and learning. Two main questions are investigated. First, how is the learning of workers organized in the knowledge creation theory? Second, how is their learning related to the work they perform? Answers to these questions are sought from case-study research into work-related learning projects (Poell 1998) and from theoretical notions about learning networks in various work types (Van der Krogt 1998). Our first conclusion is that Nonaka and Takeuchi seem to assume that workers will learn only within the boundaries set by management. They do not, however, take into account that workers organize a great deal of learning themselves, frequently irrespective of management expectations. Second, Nonaka and Takeuchi expect workers to learn according to rigid bureaucratic principles in a work context emphasizing innovation. The theory of knowledge creation does not show how these contrary principles might be successfully integrated.     

Approximately Median-Unbiased Estimation of Autoregressive Models

A hedonic model of automobile prices that takes gasoline costs into account is developed and used to examine whether gasoline price increases (especially those related to the 1973 and 1979 oil shocks) changed consumer evaluations of the relative qualities of used cars in the U.S. during 1970–1981. We test the null hypothesis that the characteristics' coefficients remained constant over time. It is rejected if gasoline costs are excluded from the model but not if they are included. Alternative approaches are developed to show that the gasoline price increases alone can explain much of the observed changes in the coefficients.     

原油高价的影响因素及对策研究

由于全球范围内石油供求矛盾突出、石油开采投资不足、有关国家石油战略储备量大幅增长和期货投机等因素,2004年国际原油平均价格达到41.47美元/桶,预计在2005年平均价格将达到45.23美元/桶,国际油价将不可避免地进入高油价时代。高油价对整个下游产业链都有着显著的影响。石油炼制、石油化工和下游加工行业应对高油价的能力,将随着与最终用户的不断接近而降低。通过建立安全可靠的原油供给体系、采用先进的生产工艺技术、扩大生产规模、产品结构的优化和降低综合能耗等一系列措施,石油化工行业可消化部分高油价所带来的压力,并适度向下游转移生产成本。在保持自身具有良好盈利的同时,石油化工行业可让出部分利润空间以促进下游加工行业的稳定发展,并有效抑制在石油化工产业上的盲目投资。     

Stress at sea: A review of working conditions in the offshore oil and fishing industries

Abstract

This paper reviews the literature available on the psychosocial aspects of the offshore oil and fishing industries. Both work sectors present unique problems for their employees and these are discussed with reference to risk and safety, accidents and injuries, occupational stressors, marriage and family life, noise, alcohol and drug abuse and personality. The paper concludes that although both occupations are intrinsically different, some psychosocial similarities can be observed.     

关于扩大我国海洋溢油生态损害索赔主体的思考——以“康菲溢油”事件为视角

我国当前立法海洋生态损害赔偿的规定模糊且索赔主体的范围狭窄,在实践中缺乏可操作性,容易导致多个行政主管部门之间职责和权限的冲突,不利于保护海洋生态损害案件的受害人,也不利于保护海洋环境。应当扩大我国海洋溢油生态损害索赔主体的范围,将检察机关、公民、法人及其他社会组织和环保非政府组织等主体都纳入海洋溢油生态损害索赔主体范围,以充分地赔偿油污受害人的损失,进而保护海洋环境。
