How do firm-specific, demand-related factors influence the relationship between intra-industry diversification (IID) and performance? Recent findings regarding the performance effects of IID depict a complex picture with curvilinear relationships and several contingencies. However, firm-specific contingencies on the demand side have remained unexplored. We analyze how IID relates to firm performance (market share) in the German automotive industry using panel data between 1999 and 2008. We specifically focus on a firm's high-quality brand image as a demand-side contingency. We find support for our hypotheses of complex curvilinear relationships as well as for moderating effects of brand quality. Our results have significant theoretical implications for the IID literature. 相似文献

Knowledge is a vital source of competitive advantage and renewal for contemporary organizations. However, to date, few studies have scrutinized how mergers and acquisitions (M&As)—processes dependent on knowledge sharing—offer a valuable inter-organizational context through which to understand the attainment of customer knowledge sharing following M&As. Applying an integrated theoretical perspective from customer relationship management and M&A performance research, we study a Chinese–Finnish acquisition and customer firms of the acquired party across four advanced Western countries. We find that customer knowledge sharing is an active relationship management process that relies on the factors of customer dedication-based motivation vs. customer concerns about M&As to maintain relationships after acquisitions. In addition, and more importantly, we find that the promise management mechanisms—making promises, enabling promises, and keeping promises—of the M&A parties reinforce the motivational factors to maintain customer knowledge sharing in cross-border M&As. We propose a conceptual framework of customer knowledge sharing in cross-border M&As. 相似文献

This paper examines the mediating mechanism of the relationship between institutional voids (IVs) and inter‐firm cooperation and the moderating role of economic adversity in the context of small and medium‐sized enterprises (SMEs) based in emerging markets. The hypotheses are tested using time‐lagged survey data from 214 SMEs in Ghana. The findings provide support for the hypotheses by showing that: (1) IVs positively influence the use of government research and development (R&D) support; (2) the use of government R&D support mediates the relationship between IVs and inter‐firm cooperation; and (3) economic adversity positively moderates the relationship between IVs and the use of government R&D support. The findings contribute to understanding the role of IVs in inter‐firm cooperation. The wider implications for theory and practice are examined. 相似文献

Model building in physical, statistical, simulation or other form, is making an increasing contribution to the problem solving methodology in economics, industry, government, and technological development (1). More specifically, in the present context, simulation models can offer a distinctive and valuable contribution to the understanding by management of complex business systems, interactions and environment and indicate ways toward improvement, financial and otherwise (2). The advent of powerful computers in the last few years is the decisive factor which has decided the means of realizing the full potential of simulation models, hitherto unattainable because of the vast amount of data processing and calculation required. The purpose of this article is to indicate the approach to and scope of a computerized simulation model for long term production strategy decision making (3). While the model relates to the system and data of a specific production unit, manufacturing electronic components, the principles are widely applicable in any size and type of company. It is not a specifically large company technique. 相似文献

New Products are the life blood of a growing company, but traditional methods of introducing new products are no longer adequate. Du Pont is using a new approach called Venture Management. A New Venture Development provides an ideal environment for making and carrying out decisions involved in introducing new technological developments. It combines the advantages in mobility and communications enjoyed by a small venture-orientated company with the strong technical and financial advantages of a large company. 相似文献

A survey of corporate Planning in Britain suggests that the way the process is organized varies with the need of the firm. There appear to be two types of needs which foster the development of the planning activity—strategy development and co-ordination. In capital intensive companies, threatened by technological or market change, there is a need for reappraisal of the firm's overall strategy. On the other hand, in a large diversified firm the requirement may be to co-ordinate the plans of different divisions and departments, particularly investment proposals. This article suggests a framework for the analysis of these planning needs. 相似文献

Nonprofit organizations should consider using incentive-based management programs so long as such programs are studied thoughtfully, implemented carefully, and closely tied to other important management practices. The article describes the experiences of one nonprofit organization, Citizens' Scholarship Foundation of America (CSFA), in successfully conducting a staff incentive program during the past several years. The author also reports briefly on the results of a recent survey among CSFA staff involved in the incentive plan, outlining the benefits of such a program in helping the organization to reach its objectives. Finally, the author addresses potential pitfalls to avoid in implementing an effective staff incentive program. 相似文献

This study explores differences in inter-household exchange of goods and services in Anglo- and Mexican-American families controlling for income level and for ethnicity. The extent of such exchange, its perceived importance to the family's quality of life, satisfaction with the exchange, and the relation of persons in the exchange process are examined. Significant differences are found more often between higher income Anglo- and Mexican-Americans than between low-income families, both in the family providing goods and services for others and in the receipt of them. Higher income Mexican-American families are more likely than their Anglo- counterparts to exchange with relatives. Ethnic effects are more prevalent in higher income households than in low-income households. Economic effects are more predominant than ethnic effects.This study contributes to interregional Agricultural Experiment Station Research Project NC-128, Quality of Life as Influenced by Area of Residence.
