创业机会共创研究探析

过往研究就创业机会的来源和产生等问题存在争议,而且聚焦于创业者、创业企业及外部环境等独立要素,割裂了创业机会在不同要素之间的互动关系。本文通过系统梳理创业机会研究的演进脉络,发现创业机会共同创造(co-creation)已成为未来研究的主要趋势。在已有研究的基础上,本文初步界定了"创业机会共创"的概念,并对相关概念进行了辨析。进一步,基于创业生态系统视角探讨了机会共创的参与要素,以此区分了实现创业机会共创的四种基本互动路径:即机会之间的互动,创业主体与机会的互动,创业主体之间的互动,创业主体与环境的互动。最后,提出了未来研究的思路与建议。     

Role of gender differences on individuals’ responses to electronic word-of-mouth in social interactions

Considering the significant effects of electronic Word-of-Mouth (eWOM), this research explores how individuals respond to eWOM and whether gender differences exist in their perceptions. To do so, by employing the perspective of social interactions, we examine the proposed relationships are different between genders. We collected data using a survey and tested the hypotheses via path analysis. The results indicate that, gender differences were found specific to search effort, product involvement, and information credibility. Women with strong online ties had a tendency to be more involved in the product information and to find the information more credible. In addition, when women had an increased search effort, they were more likely to have intention spread eWOM. This research provides insights to further research related to gender differences in eWOM by discussing implications for research and practice.     

Mixed farming in Africa: the search for order, the search for sustainability

This paper examines the interest in the development and promotion of mixed farming in sub-Saharan Africa. For over 70 years mixed farming has been a dominant model for agricultural development despite the limited success of many of the programmes which have specifically promoted it. It is suggested that the establishment of mixed farming as a strong development theme is related to its promise to address a range of environmental and social concerns, and in so doing, help create order out of a ‘chaotic’ African countryside. Mixed farming is again being highlighted with the more recent interest in sustainable, environmentally friendly agricultural systems. However, there is considerable evidence that African farmers have adopted a flexible principles-based approach to the use of component technologies commonly associated with the mixed farming model. This must be fully acknowledged, and the seduction of unitary models avoided, if agricultural research is to contribute efficiently to the development of more sustainable farming systems.     

基于价值工程的企业竞争优势构建

动态复杂的环境下,应当树立什么样的经营理念,采取何种经营机制、何种管理技术获取竞争优势,实现可持续发展,益已成为企业面临的迫切课题。与其同时,价值工程(简称VE)作为现代思想方法和管理技术,应用领域不断扩充,出现了不少以企业管理为研究对象的优秀成果。在此背景下,本文把价值工程运用于企业竞争优势构造,从竞争优势的四个层面展开,试图构造一个以功能为导向的竞争优势构造模式。

Management heterogeneity,competitive interaction groups,and firm performance

One of the fundamental problems in strategic management is to map a heterogeneous set of firms in an industry into subsets of firms within which firms are homogeneous in their conduct and performance. The strategic group concept provides an answer to this intriguing question. Researchers in strategic group theory argue that firms within the same strategic group are behaviorally similar and thus tend to compete more fiercely within the group than across groups. In this paper, we focus on the question whether firms within the same group show similar decision‐making characteristics. Strategic‐choice theorists argue that top management teams in firms have substantial discretion in determining the future strategic contour of firms. Upper‐echelon theorists also argue that top managers are the strategists who set the direction of firms and the pace of competition in the industry. Further, they argue that top management team characteristics are an important element that determines the market niche in which a firm competes and the strategic direction a firm follows. Based on these arguments, we expect that there will be a significant link between grouping of firms by the patterns of competitive interactions and grouping of firms by top management team heterogeneity. Moreover, we argue that the closer the TMT heterogeneity of a firm is to the dominant heterogeneity in the competitive interaction group, the better it performs.

项目组合选择研究：基于模糊理论的模型建构及验证

项目组合的选定与企业经营息息相关,然而传统的选择方法存在许多限制。本文应用模糊理论建构一个项目组合的决策模型,模型中纳入了成本、利润及风险等3个决策因子,探讨在资源有限的情况下项目成本及获利的交互影响关系,并利用模糊归属函数建构一个数学规划模型。为了验证模型的有效性,用此模型与传统模型进行求解比较,证实了所提出模型的实用性。
