Severe socio-economic issues that threaten peace, life or wellbeing of humans in specific regions of the world cannot be solved by any single actor. Wide networks of political, business, governmental, non-profit and humanitarian organizations are to be involved to change existing practices. Despite conflicting interests and competing behavior, involved organizations need to act collectively to initiate the change of commonly accepted practices, i.e. institutions. This is the space in the present study for examining network mobilization as a collective means to change institutions. Our aim is to answer the question: How are networks mobilized in crisis management to initiate institutional change processes in socio-economically turbulent contexts? We provide a framework of network mobilization for institutional change built on the IMP rooted network mobilization research and institutional entrepreneurship discussion. The framework is reflected upon by means of insights from an interview-based case study with representatives of governmental and non-governmental organizations involved in worldwide humanitarian peace-building. We identify, firstly, incentivizing, reticent and adaptational behaviors of network mobilizers to utilize legitimacy and relationship sediments as mobilization enablers. Secondly, these behaviors help network mobilizers to overcome actor visibility and unpredictability as mobilization obstacles in turbulent contexts.  相似文献

Based on an existing conceptualization in the literature, this study operationalizes the construct of organizational networking, through a rigorous two-stage scale construction and validation process. Organizational networking refers to firm behaviors, i.e. the activities/routines/practices, which enable an organization to make sense of and capitalize on their networks of direct and indirect business relationships. We conceptualize the measurement model as a second-order formative construct with four first-order reflective constructs based on a four-dimensional view of organizational networking comprising information acquisition, opportunity enabling, strong-tie resource mobilization and weak-tie resource mobilization. The scale validation was undertaken at the first- and second-order levels. The result confirms the four distinct first-order measurement models. At the second-order level, a MIMIC (multiple indicators and multiple causes) model was employed to assess the validity of the formative measurement model. The results suggest that all four components significantly contribute to the overarching construct of organizational networking, with strong-tie resource mobilization being the most important contributor. Thus, our operationalization confirms the uniqueness of the different dimensions of organizational networking that should be configured as a strategy of sensing and seizing opportunities in the network. The organizational networking scale will provide future research with a basis to explore different strategic patterns of networking behaviors in varying contexts, and its role in relation to other organizational behaviors and outcome variables, such as firm performance.  相似文献

This paper explores the managerial challenges facing firms seeking to build relationships with other network actors while doing business in foreign markets. By taking a critical perspective on an area of increasing importance in both manufacturing and service sectors, that of value co-creation, the paper explores how managers in different cultural contexts make sense of the notion of ‘value’ in inter-organizational B2B relationships between New Zealand service and service-infused supplier firms and buyers in China and India. From an analysis of the interview-based accounts on both sides of the buyer–seller dyad marked differences emerge regarding value-creation within managers' discourse around partnerships, collaboration and cooperation. Our findings suggest that the Indian manager's discursive use of ‘partnership’ draws on service-dominant logic in viewing this type of interaction as a means for co-creating value; they and their New Zealand suppliers are jointly involved in co-creating value within a service system, creating value-in-use. In contrast, the predominant perspective seen in the discourse of Chinese managers is the use of cooperation as a means of making transactions more cost-effective, or to fill gaps in their supply chains, resulting in the creation of transaction-based, co-production of value, which suggests a value-in-exchange orientation. In both cases, there is repeated reference to more peripheral actors whose efforts result in what we interpret as network value creation, based on their interactions with actors within the buyer–seller dyad.  相似文献

Network losses and returns are importantissues for water resource management, that are addressed in thispaper by modeling the structure of production for municipal waterutilities with two outputs: water sold to final customers andwater network losses. We propose a measure of economies of scopeto assess the benefit associated with joint production of waterfor final customers and water losses, and several measures ofreturns to evaluate potential gains in exploiting technologicalflexibility of water networks. We estimate the cost structureof water utilities using a GMM procedure with a Translog costfunction and panel data. Estimation results reveal a positivedegree of economies of scope, and short-run returns to productiondensity and returns to customer density that are not significantlydifferent from 1. Significant economies of scale indicate thatlocal communities may benefit from merging into water districts.  相似文献
