Application of collective knowledge diffusion in a social network environment

ABSTRACT

We present a group dynamics model that shows knowledge integration as a process occurring over time. As each individual in the group contact others, his own knowledge changes, and over time the collective knowledge is obtained. This allows modeling knowledge diffusion in a social network and while the models presented in this paper are not competitive in that area, they approach the problem from previously unconsidered direction. We test the behavior of the model in a multi-agent simulation and we test a simple advertisement campaign in a social network. We provide discussion of elements needed for making model more competitive.     

中蒙俄经济走廊建设中内蒙古与蒙、俄产能一体化分析——以钢铁、水泥为例

在“一带一路”倡议背景下,内蒙古凭借地缘优势、人文优势正在积极参与中蒙俄经济走廊的建设,并发挥着重要作用。内蒙古通过对蒙、俄输出钢铁和水泥,对促进内蒙古的经济增长起到了一定的积极作用。本文利用TVP－VAＲ模型实证检验证实,内蒙古对蒙、俄在钢铁、水泥的产能输出,短期内对第二产业的增长影响较为显著,但中期影响减弱,长期影响不明显。因此,内蒙古应抓住机会,通过产能一体化进一步化解钢铁、水泥过剩产能,从而实现产业结构升级和创新发展。

Environmental Requirements,Knowledge Sharing and Green Innovation: Empirical Evidence from the Electronics Industry in China

Building on the Porter hypothesis, which posits that regulatory stringency triggers innovation and thereby allows firms to achieve the dual purpose of environment protection and enhanced business performance, the present research develops an integrative model that explores the determinants of green innovation with a focus being placed on knowledge sharing. Data were collected from 203 green innovation project leaders from electronics manufacturers operating in China. The results indicate that knowledge sharing mediates the relationship between green requirements and new green product success as well as that between green requirements and green product and process innovations. Interestingly, the empirical analysis rejects the hypothesized positive influence of green requirements on green product and process innovations as well as that on new green product success, while confirming that there exists a direct and positive association between green requirements and knowledge sharing. The direct positive impact of knowledge sharing is the strongest on green process innovation. This study provides a theoretical basis for investigating the possible determinants in the causal links between green requirements and green innovation success and establishes that knowledge sharing and green process innovation may be the points where leverage can be applied to best secure innovation success. Implications of the findings on environmental policy and law design are also discussed to see how the regulatory role of the government can be better positioned to facilitate compliance and innovation.

Leadership,Creative Problem‐Solving Capacity,and Creative Performance: The Importance of Knowledge Sharing

This article presents two studies that examine whether leader supportive behaviors facilitate knowledge sharing and employee creative problem‐solving capacity, thereby enhancing creative performance. The findings from both studies indicate that leader supportive behaviors are directly and indirectly related, through both internal and external knowledge sharing, to employee creative problem‐solving capacity. In addition, creative problem solving was related to the two dimensions of creative performance—fluency and originality. However, a test of the mediation model indicated that creative problem solving only mediated the relationship between internal knowledge sharing creative performance and originality. These findings highlight the complex process by which leaders facilitate both internal and external knowledge sharing and employee creative problem‐solving capacity, thereby improving employee creative performance.     

Weakly rational expectations

Aumann and Drèze (2008) characterised the set of interim expected payoffs that players may have in rational belief systems, in which there is common knowledge of rationality and a common prior. We show here that common knowledge of rationality is not needed: when rationality is satisfied in the support of an action-consistent distribution (a concept introduced by Barelli (2009)), one obtains exactly the same set of rational expectations, despite the fact that in such ‘weakly rational belief systems’ there may not be mutual knowledge of rationality, let alone common knowledge of rationality. In the special case of two-player zero-sum games, the only expected payoff is the minmax value, even under these weak assumptions.     

Encouraging knowledge sharing among employees: How job design matters

Job design is one of the most frequently researched practices in the Human Resource Management (HRM) literature, and knowledge sharing has become an important and heavily researched managerial practice. The links between these practices, however, have received little attention in the literature. We argue that job design matters to knowledge sharing for motivational reasons. Specifically, jobs contain characteristics that stimulate different kinds of motivation toward knowledge sharing, which have different effects on individual knowledge sharing behavior. We develop six hypotheses that unfold these ideas and test them on the basis of individual‐level data collected within a single firm. The hypotheses are tested in a LISREL model that confirms that job characteristics, such as autonomy, task identity, and feedback, determine different motivations to share knowledge, which in turn predict employees' knowledge sharing behaviors. © 2009 Wiley Periodicals, Inc.     

Characteristics of Portuguese public‐sector project managers: Toward closing the effectiveness gap

Using a sample of 102 Portuguese public‐sector officials with project management experience, this study examines the characteristics of effective project managers in the Portuguese public sector. Factor‐analysis procedures are used to identify the factors related to areas of knowledge relevant to effective project management. The results appear to stress the increasing importance of people, organizational, and leadership skills in the effective management of today's complex and dynamic projects.     

跨境电商综合试验区试点政策如何影响电商行业发展

理解政府政策对电商行业发展的作用效果,事关我国电商行业发展以及各级政府的正确决策。通过构建一个基于知识螺旋演化的概念模型,探究跨境电商综合试验区试点政策对电子商务行业发展作用的内在机理,并在此基础之上提出研究假说,然后采用双重差分方法对研究假说进行实证检验,检验结果表明：在剔除其他因素影响的条件下,跨境电商综合试验区试点政策的实施能够促进电商行业发展。进一步研究发现：试点政策对电商行业发展的促进作用存在城市异质性,即地级城市作用最大,其次为副省级城市,再次为省会城市。因此,政府在制定促进电商行业发展的相关政策过程中,应将政策重点放在电商行业发展水平尚待提高的地级城市(除副省级和省会城市之外),试点政策在这些城市的作用效果更大。另外,我国西部地区的政策重点应放在加强电子商务行业发展的配套设施建设,这样才能提高试点政策的作用效果。
