Technological diversification, complementary assets, and performance   总被引:2,自引:0,他引:2  
Most research on technological diversification or complementary assets has been carried out in isolation when assessing their effects on performance. In this study, we posit that technological diversification and performance are positively linked and that specialized complementary assets have a moderating effect on this relationship. This study also finds that different specialized complementary assets have distinctive moderating effects on the relationship between technological diversification and performance. We conclude that maintaining a coherent relationship between technological diversification and specialized complementary assets give firms generates competitive advantage.  相似文献

前很多国家都已建立生产者责任延伸制度,该制度是循环经济的一项基本制度。但是国内外对"谁是生产者"存在很大争议,争议的焦点在于产品原材料生产者、产品零部件生产者等间接生产者是否也属于该制度生产者的范畴。本文分析了目前国内外关于生产者的界定,阐述了将间接生产者纳入生产者范围的必要性及理论基础,建议将生产者责任延伸制度的生产者扩张为直接生产者和间接生产者,并合理分担延伸责任。所以,明确谁是生产者,将更加有利于生产者延伸责任的承担。  相似文献

The purpose of this study is to investigate the moderating effect and the interactive effect of job scope, role ambiguity and participation in decision-making on relationships between career plateauing and outcomes. A cross-sectional survey of 3,065 Canadian managers shows that these job characteristics can contribute to limiting the negative consequences associated with career plateauing. Moreover, in accordance with the theory of work–situation fit, some double moderating effects are found. The attitudes and behaviours of plateaued managers are significantly more positive when their job is richer and offers an opportunity to participate in decision-making. However, contrary to evidence in the literature, results show that reactions to career plateauing are more positive for managers who perceive that their job is richer and their role more ambiguous. Implications and directions for future research are discussed.  相似文献

关于地方公共财政支出体系的思考   总被引:1,自引:0,他引:1  
近年来,我国地方政府一直致力于构建公共财政体系,其中心环节就是建立科学、规范的地方公共财政支出体系。构建地方公共财政支出体系是个空间立体模型,主要包括公共财政支出的框架和框架里的内容。公共财政支出框架主要是指横向的公共财政支出范围、纵向的财政支出规模;框架里的内容则主要是指地方财政支出结构。  相似文献

Upper echelons and portfolio strategies of venture capital firms   总被引:1,自引:0,他引:1  
In this study we analyze how the composition of the top management team (TMT) influences the portfolio strategy choice in venture capital (VC) organizations. We develop a model of risk perception to investigate how education and experience of TMT members impact whether VC organizations invest with a focus on early stage ventures or not, specialize or diversify across industries, and invest with a broad or narrow geographic scope.Evaluation of data on TMTs and portfolio strategies of 136 European VC firms revealed that VC firms with higher proportions of TMT members with science/engineering education and entrepreneurial experience more likely invest with an early stage focus. Furthermore, TMTs with more management education diversify their portfolios more across industries. Finally, the more international experience TMT members of VC organizations have, the broader the geographic scope of investees. We discuss the implications of our findings for the VC literature.  相似文献

We study how intra‐industry product diversity affects firm performance by analyzing the implications of expanding a firm's product line within its core business. We conjecture that increases in product diversity initially undermine performance because of negative transfer effects but then improve it due to economies of scope. We further theorize that this U‐shaped effect of product diversity becomes more pronounced as the firm increases the intensity of its technology investment, yet is likely to be attenuated by the firm's accumulated experience with intra‐industry diversification. Data on 156 U.S.‐based software firms operating from 1990 to 2001 furnish support for these conjectures. Our study advances emerging research on intra‐industry diversification by underscoring some of its contingent performance effects. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

Using a research model based on customer value theory, this study investigates the determinants of customer post-purchase price comparison searches in the context of online price-matching guarantees (PMG). Data collected from 222 eligible respondents are tested against the proposed research model using partial least squares structural equation modeling (PLS-SEM). The results indicate two PMG characteristics, refund length and refund scope, influence utilitarian benefit (i.e., refund depth) and hedonic benefit (i.e., playfulness). These two benefits subsequently contribute to customer perceived value, which leads to price search intentions. This study pioneers the exploration of online PMGs and the determinants of customer post-purchase price search intentions. Several important theoretical and practical implications can be drawn from the findings to guide online retailers’ PMG strategies.  相似文献
