The role of networks in business operations is widely recognized. We discuss social network theory, identify its main constituents, and outline a methodology and procedure that enable the identification and valuation of informal networks in an international business-to-business environment. Research is carried on informal Internet networks among firms in the biotechnology industry from Sweden and Australia. We use the methodology to recognize salient nodes, determine prominence and identify structural holes that allow the unveiling of brokerage opportunities that lie latent in networks. Global firms and suppliers of industrial products that are or can position themselves effectively in a social network are in a position to leverage considerable value.  相似文献

This paper introduces a metatheoretical, contingency-based framework of inter-organizational network management. We define four basic network management functions and suggest that they are universal to all inter-organizational networks. We argue that management tasks, derived from more general management functions and contingent upon network characteristics, differ according to network type. We further argue that the roles that different actors in a network can adopt depend on their resources and capabilities. The framework contributes to the emerging theory of network management by clarifying the connections between its different conceptualizations and layers. A clear implication of the framework is that it is fundamentally useless to argue that networks cannot be managed. Networks are being managed, all of the time. However, we agree that the extent to which networks can be managed differs from one network to another along with the managerial tasks employed.  相似文献

This paper develops a case study approach that builds on the foundations of moderate constructionism and abduction. We discuss the case study method and its role in industrial marketing, especially in business-to-business networks. Moderate constructionism is compared with realist, critical realist, and relativist approaches. We argue that moderate constructionism takes better into account the multiple constructed, community-bounded realities that all case studies inevitably deal with. The power of moderate constructionism to produce valid and generalizable new knowledge is critically assessed. We also address abduction in relation to induction and deduction and its role in the moderate constructionist research approach. Finally, we develop a process model, illustrated by a case study of a specific network in the pharmaceutical industry.  相似文献

This paper examines why and how firms participate in issue networks that aim at solving contemporary complex problems. We build mainly on network and stakeholder literatures to understand mobilization from a relational perspective. Drawing on a single embedded case study of four initiatives to save the Baltic Sea, we build a multilevel model for firm participation in issue networks. Besides discovering diverse motivational factors, the model sheds light on the interaction between individual, organization, and network levels factors explaining mobilization. We argue that there is high theoretical, managerial, and societal relevance for studying the dynamics of issue networks—a topic which could be better incorporated in the research agenda of business network scholars.  相似文献

The Korean government has played a crucial role in the development of advanced mobile networks, including 5G. Korea became the first country in the world to not only launch a nationwide 5G network but also to commercialize 5G services. In addition to looking at the steps toward 5G-related developments in Korea, this study used Latent Dirichlet Allocation (LDA) topic modeling analysis to examine how 5G-related discourse was formed in the media after its commercialization. As a result of analyzing news articles in the Korean press with 5G as the main keyword, a total of five topics were derived. Intriguingly, most topics contained several new articles related to government policies. Considering the characteristics of the mobile network industry—e.g. as an industry that receives licenses from the government—this result suggests that 5G-related issues are closely related to government policies. Our topic modeling results confirm that the interventionist promotion policy of the Korean government which acted as a catalyst for technology and business innovation played an important role in Korea's 5G leadership.  相似文献

The interest in supply chain networks and their analysis as complex systems is rapidly growing. The physical approach to the topic draws on the concept of heterogenous interacting agents. The interaction among agents is considered as a repeated process of orders and production. The dynamics of production in the supply chain network which we observe is nonlinear due to the random failures in processes of orders and production. We introduce an agent-based model of a supply chain network which represents in more detail the real economic environment in which firms operate. We focus on the influence of local processes on the global economic behavior of the system and study how the proposed modifications change the general properties of the model. We observe collective bankruptcies of firms, which lead to self-emerging network structures. Our results give insight into the dynamics of default processes in supply chain networks, which have important implications both for risk managers and policy makers. Based on the simulations we show that agent-based modeling is a powerful tool for optimization of supply chain networks.  相似文献

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.  相似文献

In this paper, I interpret a time series spatial model (T-SAR) as a constrained structural vector autoregressive (SVAR) model. Based on these restrictions, I propose a minimum distance approach to estimate the (row-standardized) network matrix and the overall network influence parameter of the T-SAR from the SVAR estimates. I also develop a Wald-type test to assess the distance between these two models. To implement the methodology, I discuss machine learning methods as one possible identification strategy of SVAR models. Finally, I illustrate the methodology through an application to volatility spillovers across major stock markets using daily realized volatility data for 2004–2018.  相似文献

Many regions on earth face daily limitations in the quantity and quality of the water resources available. As a result, it is necessary to implement reliable methodologies for water consumption forecasting that will enable the better management and planning of water resources. This research analyses, for the first time, a large database containing data from 2 million water meters in 274 unique postal codes, in one of the most densely populated areas of Europe, which faces issues of droughts and overconsumption in the hot summer months. Using the R programming language, we built and tested three alternative forecasting methodologies, employing univariate forecasting techniques including a machine-learning algorithm, with very promising results.  相似文献
