国际大石油公司增储上产经验及启示

2018年国际大石油公司油气产量和上游投资都有增长,上游利润、投资回报率大幅提高,预期2019-2020年上游领域继续保持增储上产的态势.国际大石油公司增储上产的典型做法有:加大上游投入,重组上游业务,实施稳健的勘探投资计划,风险勘探投资相对稳定,上游投资多元化,整合核心资源,加大资产并购力度,关注热点地区,加强扩边勘探,灵活设置项目开发方式,始终保持高强度的研发投入等.国内石油公司对上游勘探投入保障不足,可采储量增长后劲有限,削弱了油气上产稳产的储量基础,需借鉴国际大石油公司增储上产经验,在上游勘探开发以及降本增效环节进行优化调整,探讨增加产储量以及降本增效的途径.     

经济转型期多元化经营的风险及对策

多元化还是专业化,这是企业发展过程中常遇到的问题,也是企业最困惑的问题之一。一般地,当宏观经济处于增长期,则行业发展趋好,行业竞争较弱,此时多元化经营比较容易成功;当宏观经济处于成熟期和衰退期,则行业发展趋势变坏,行业竞争加剧,多元化经营则难以成功。经济转型将使传统行业的发展趋势受到不利影响,从而加大多元化经营的风险。     

商业银行多元化经营对绩效和风险的影响研究--基于53家银行的面板分析

本文运用2003-2013年间我国53家商业银行的面板数据,通过建立多元化风险模型,对商业银行收入结构多元化、经营绩效以及风险的关系进行了系统分析。得出结论：规模较大的银行在专业型多元化经营业务成熟的基础上,转而发展综合型多元化经营业务,有利于银行绩效提升,但必须注重对风险的把控;而规模较小的商业银行因受地域、规模等因素的限制并不适合开展综合型多元化经营业务,应在主营业务发展充分的基础上,以发展专业型多元化经营业务为主。最后,根据实证结果提出相关的对策建议。     

Endogenous location leadership

We analyze a game of timing where Sellers, which have marginal production cost asymmetries, can delay entry and a commitment to a location in a Hotelling type setting. When cost differences are large enough the game becomes a war of attrition that yields Stackelberg behavior where the high cost firm will delay choosing a location until the low cost firm commits to its position. We find interaction effects between timing and the degree of product differentiation and compute timing/location and mixed strategy equilibria through a range of marginal cost differences. The firms maximally differentiate with moderate cost differences; with somewhat greater cost differences there is intermediate differentiation, and; with large cost differences there is a blockading monopoly. The low cost firm always commits to entry immediately whereas the high cost firm either enters immediately, shortly after the low cost leader, or never, depending on the cost differences. Finally, we find that in equilibrium the duopoly is sustained for a larger range of cost differentials and that differentiation is greater than the social optimum.     

The independent and joint effects of the skill and physical bases of relatedness in diversification

By examining the independent and joint effects of the skill and physical bases of relatedness, this study develops a multidimensional view of relatedness in diversification. The paper compares the ways the two bases identify relatedness, and examines empirically the relationship between relatedness and performance for a sample of 158 large diversified manufacturing firms. Each base of relatedness alone had no significant effect on financial performance. However, when the two approaches were combined, there was a strong positive effect on most indicators of performance. The findings demonstrate how different bases of relatedness complement and extend one another, and they clarify findings of previous studies that used a single base of relatedness. © 1998 John Wiley & Sons, Ltd.     

SIMILARITY JUDGMENTS IN STRATEGY FORMULATION: ROLE,PROCESS AND IMPLICATIONS

Similarity judgments are an important and distinct aspect of strategy formulation. They are manifest in strategic decisions and errors, and in the construction of analytic concepts such as strategic groups and relatedness in diversification. However, existing models of strategy formulation either assume away the process of making similarity judgments or regard it as unproblematic. This paper highlights the role of similarity judgments in strategy formulation, and discusses cognitive findings showing that decision makers’ assessment of similarity is not free from bias. The cognitive findings help construct a new process explanation for a wide range of apparently isolated strategic errors. The process explanation is contrasted and integrated with traditional explanations based on imperfections in decision inputs. Finally, in light of the cognitive findings, the methods and assumptions of existing approaches in strategy formulation research to the construction of analytic concepts are reexamined. © 1997 by John Wiley & Sons, Ltd.     

The dynamics of innovation and horizontal differentiation

We study innovation in a dynamic stochastic discrete-time duopoly with endogenous horizontal differentiation. Innovation takes the form of a quality ladder; horizontal differentiation is Hotelling competition. We compute Markov-perfect equilibria and study the effects on long-run innovation of changes in taste heterogeneity (transport costs) and firms' costs of relocating products. Innovation rises as the industry's long-run position moves toward products that are permanently co-located in the space of horizontal tastes. A large enough fall in taste heterogeneity will raise long-run innovation, while more costly product relocation lowers innovation if taste heterogeneity is high, and raises it otherwise.
