Entrepreneurial ecosystems

International business fundamentally is about creating an ecosystem environment conducive to entrepreneurship. This means fostering actions and behavior that provide a systemic interaction with multiple entities. In this editorial for the special journal issue, the historical background and origins of the entrepreneurial ecosystem concept is discussed with the view to connected different strands of literature. This provides an optimal way to understand the way entrepreneurship develops through an ecosystem logic. The theoretical perspectives for understanding entrepreneurial ecosystems are discussed that lead to a discussion on each of the articles included in the special journal issue. Themes emerging from these articles are then stated that include a focus on value co‐creation, stakeholder collaboration and entrepreneurial networks. This enables a holistic way to understand the linkages international business has with entrepreneurial ecosystems.     

Digital sport entrepreneurial ecosystems

The entrepreneurial ecosystems literature has increasingly explored network relationships between different stakeholders, as well as the role of context. This article addresses the challenge of including a sport context in the entrepreneurial ecosystem literature thereby contributing to the sport entrepreneurship literature by bringing insights from entrepreneurship ecosystem research. In‐depth interviews of football stakeholders in the sport entrepreneurship ecosystem are conducted in terms of understanding the emergence of digital sport start‐ups. The issues raised help explore the changing nature of digital entrepreneurial ecosystems to take into account new sport technological advances. Mixed embeddedness theory is used as the conceptual foundation to understand sport digital entrepreneurial ecosystems. Key management practices are identified in terms of sport start‐ups participating in entrepreneurial ecosystems. The article concludes by making suggestions for future research.     

金砖国家在国际创新合作网络中的地位和角色研究

金砖国家是世界科技创新的重要新兴力量,虽受到国际形势的影响其专利合作网络规模有所下降,五国之间的合作并不紧密,但它们的网络地位稳中有升、态势向好。中国在国际专利和论文合作网络中的活跃度和影响力均不断增强,具有信息和资源控制的巨大优势;俄罗斯与印度地位相似,但俄罗斯的国际专利与论文合作地位均有所提升,而印度的地位正在弱化;巴西在论文合作网络中相对较具优势地位,但在专利网络中巴西则与南非共同位于边缘区。     

供应链网络均衡模型

本文试图提出一种供应链网络的均衡模型。在这个模型里将充分考虑决策者的决策与他们各自独立的行为,并推导出供应链网络模型结构均衡的条件。     

基于复杂组织内个体差异的隐性知识传播模型研究

隐性知识是企业存亡、取得竞争优势的关键性资源。在组织内,不仅宏观的网络结构会影响隐性知识的传播,而且微观层面的个体差异也会对其有很大的影响。组织管理者应通过提高员工个体的知识转移能力、知识吸收能力以及个体间的信任度来促进隐性知识的高效传播,提高组织的核心竞争力。     

Discovering latent commercial networks from online financial news articles

Unlike most online social networks where explicit links among individual users are defined, the relations among commercial entities (e.g. firms) may not be explicitly declared in commercial Web sites. One main contribution of this article is the development of a novel computational model for the discovery of the latent relations among commercial entities from online financial news. More specifically, a CRF model which can exploit both structural and contextual features is applied to commercial entity recognition. In addition, a point-wise mutual information (PMI)-based unsupervised learning method is developed for commercial relation identification. To evaluate the effectiveness of the proposed computational methods, a prototype system called CoNet has been developed. Based on the financial news articles crawled from Google finance, the CoNet system achieves average F-scores of 0.681 and 0.754 in commercial entity recognition and commercial relation identification, respectively. Our experimental results confirm that the proposed shallow natural language processing methods are effective for the discovery of latent commercial networks from online financial news.     

国有企业双重目标与投资效率改进——基于独立董事网络和国企混改视角

立足国有企业具有社会和经济双重目标的理论逻辑,本文选取2007~2016年A股国有上市公司作为研究样本,分析了独立董事网络和国有股比例对投资效率的影响以及调节效应。研究发现:独立董事网络降低了国有上市公司的投资效率,较高比例的国有持股抑制了投资效率,但当国企更加关注经济目标时,则有助于改善投资效率;进一步研究发现,相比于特定功能类企业,独立董事网络在商业竞争类企业中发挥投资效率的改善作用更加显著。因此,独立董事应因地制宜在国企中发挥治理作用;政府应分类推进国企混合所有制改革;竞争性国企应引入较大比例的优质民营资本,优化投资决策、提高投资效率。     

社会资本对大学生就业的差序性影响

在中国传统社会的大背景下,充分继承马克·格兰诺维特＂弱连带＂理论和费孝通＂差序格局＂理论的基础上,将弱关系理论、社会资本理论以及＂差序格局＂理论相比照,分析中国大学生无论在职业选择还是就业倾向上都受家庭社会关系网所拥有的社会资本量的多少的影响,从而进一步分析社会资本（家庭背景）对大学生就业的差序性影响。     

全球化下珠三角本土企业创新网络的演变及影响因素研究——基于顺德东菱凯琴集团和珠海德豪润达集团的对比实证

创新网络是经济地理学研究的前沿主题之一。通过考察东菱和德豪润达两家本土家电企业自成立以来创新网络的演变过程,发现两家企业的创新网络的演变呈现出较大的差异。通过进一步的研究发现,珠三角本土企业创新网络的演变是全球化和地方化因素共同影响的结果,而全球化下的"供应商-客商"关系、企业发展战略、区域内企业之间的互动关系与区域性的制度安排和环境是影响珠三角本土企业创新网络演变的主要因素。     

欠发达农区产业集群的网络组织结构及其区域效应分析

基于河南农区三个不同网络类型集群129家企业的调查,运用社会网络分析法,通过对比三个集群中的衍生网络、情感网络、咨询网络以及合作网络的网络特性,鉴别出欠发达农区集群网络中的核心节点、重要关系及不同网络组织类型的区域效应.研究发现:先导企业是集群衍生的孵化器,亲属或厂属关系是区域产业繁衍的关键渠道;大企业是技术创新和扩散的中心,供需关系和技术工人流动是区域学习的重要路径;中等企业是情谊联系的活跃点,长期合作关系能培养区域信任;中介组织与服务机构、"生产组织者"是企业间合作的"桥梁",上下游的经济联系对区域合作影响巨大.从集群的网络组织类型来看,混合性的转包网络和互补性的垂直网络比竞争性的水平网络对区域内的网络学习、信任培养、合作行动以及区域发展能带来更好的效果.
