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。  相似文献

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。  相似文献

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.  相似文献

The question of whether corporations add value beyond that created by individual businesses has engendered much debate in recent years. Some of this debate has focused on the pros and cons of related vs. unrelated diversification. A standard explanation of the benefits of related diversification has to do with the ability to obtain intra‐temporal economies of scope from contemporaneous sharing of resources by related businesses within the firm. In contrast, this paper deals with inter‐temporal economies of scope that firms achieve by redeploying resources and capabilities between related businesses over time, as firms exit some markets while entering others. The transfer of resources due to market exit distinguishes our treatment of inter‐temporal economies of scope from standard intra‐temporal economies of scope. In addition, these inter‐temporal economies can benefit from a decentralized and modular organizational structure. This ability to obtain inter‐temporal economies of scope via organizational modularity and recombination suggests that corporations do not necessarily need a high degree of coordination between business units in order to benefit from a strategy of related diversification.

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.  相似文献

The empirical analyses of firm diversification decisions, both for new activities (new products) and markets (for example, new routes for airlines), have usually estimated a binary dependent variable model for each of the decisions the firm makes. To obtain consistent estimators, every relevant effect must be considered in the specification. As this will hardly happen, the presence of nonobserved firm effects (either because such data do not exist or because it is impossible to obtain them) must be econometrically treated, because it causes inconsistency in the estimations. In this paper we propose to use the estimators provided by the maximization of the conditional likelihood function in problems of this kind because they give consistent results even when unobserved firm effects are present. Finally, we apply this technique to an example of diversification among Spanish manufacturers. © 1997 John Wiley & Sons, Ltd.  相似文献

This study investigates the level of risk due to fat tails of the return distribution and the changes of tail fatness (TF) through portfolio diversification. TF is not eliminated through portfolio diversification, and, interestingly, the positive tail has declining fatness until a certain level is reached, while the negative tail has rising fatness. This indicates that fat tails are highly relevant to common factors on systematic risk and that the relevance of common factors is higher for the negative tail compared to the positive tail. In the portfolio diversification effect, the declining fatness of the positive tail further reduces risk, but the rising fatness of the negative tail does not contribute to this effect. The asymmetry between the fatness of the positive and negative tails in the return distribution corresponds to the asymmetry of the trade-off relationship between loss avoidance and profit sacrifice that is expected as a consequence of portfolio diversification. Investors use portfolio diversification to reduce their risk of suffering high losses, but following this strategy means sacrificing high-profit potential. Our study provides empirical confirmation for the practical limitation of portfolio diversification and explains why investors with diversified portfolios suffer high losses from market crashes. An examination of the Northeast Asian stock markets of China, Japan, Korea, and Taiwan show identical results.  相似文献

Over the last two decades, extensive literature has examined the socioeconomic and environmental impacts of China's Sloping Land Conversion Program (SLCP), a program that was launched in late 1990s to mitigate the environmental effects of agricultural production and reduce rural poverty. However, little empirical evidence exists with regard to the impact of SLCP on rural households' sensitivity to nature-induced changes and environmental challenges. In this study, household-level data covering the period 1995–2010 from five Chinese provinces were used to examine the effect of SLCP on farmers' sensitivity to climate change. The empirical results show that participation in SLCP significantly reduced farmers' sensitivity to climate change by reducing their dependency on land and natural resources for income, and by diversifying their livelihood options. Spatially, the results reveal that the effect of SLCP on farmers' sensitivity vary across regions. Specifically, SLCP was found to have a ‘rate effect’ on farmers in the Northern regions and a ‘level effect’ on farmers in the Southern regions. Likewise, we found that the effect of SLCP differs considerably across income groups, with the effect on low- and middle-income groups being most significant. The results indicate that subsidy is the main pathway through which SLCP reduces farmers' sensitivity to climate change. In contrast, we found inclusive evidence about the indirect effect of SLCP farmers' sensitivity through the promotion of non-agricultural employment. These results carry major implications with regard to the effectiveness of ecological conservation programs and their mitigation potential through building farmers' resilience in China and ecologically fragile environments.  相似文献

Distance functions are increasingly being augmented, with environmental goods treated as conventional outputs. A common approach to evaluate the opportunity cost of providing an environmental good is the exploitation of the distance function's dual relationship to the value function. This implies that the opportunity cost is assumed to be non‐negative. This approach also requires a convex technology set. Focusing on crop diversification for a balanced sample of 44 cereal farms in the East of England for the years 2007–2013, this paper develops a novel opportunity cost measure that does not depend on these strong assumptions. We find that the opportunity cost of crop diversification is negative for most farms.  相似文献

Emerging markets suffer from institutional voids, and in such resource deficient economies, corporate social responsibility is given scant attention. However, when firms from emerging markets globalize, international stakeholders become suspicious about firms’ products, services, and business practices. Grounded in the liability of emergingness and legitimacy theory and using a sample of 134 manufacturing firms from one emerging market, India, this study explores how firms’ international diversification intent and market-seeking motives influence emerging markets’ firms communication of socially responsible activities as an attempt to eliminate illegitimacy. Furthermore, the study reveals that business group affiliation enhances the influence of internationalization on firms’ communication of socially responsible activities.  相似文献
