本文以修正Antràs et al(2012)模型为切入点,首次构建了生产性服务资源环节错配的测度方法,进而以WIOD数据库中发展中国家为样本首次细致分析了生产性服务资源环节错配对高技术产品出口的作用机理。研究发现:首先生产性服务资源环节错配系数对发展中国家高技术产品出口的作用力呈现倒U型,生产性服务资源环节错配不利于发展中国家高技术产品的出口,这一结论在分位数回归、控制内生性、分时间段和分产业等条件下依然稳健;其次中国生产性服务资源环节错配系数在所有样本国中最高,中国生产性服务资源过于偏向上游原料环节导致了上述现象的出现,这使得中国生产性服务资源处于“偏离最优值较远的低效扭曲使用”状态;最后高等教育、企业经营环境和经济效率均对高技术产品出口具有较为显著的促进效应,而“资源诅咒”使得丰裕的资源禀赋对高技术产品出口表现出一定的负效应,空间型贸易地理优势和契约型贸易地理优势均有助于高技术产品的出口,金融危机则对高技术产品出口产生了较为显著的负向冲击。  相似文献

本文在测度制造业和服务业中间品进口技术复杂度的基础上,剖析了中间品进口技术复杂度对中间品进口依赖的作用机制及其作用渠道,并进一步分析了中间品进口技术复杂度对经济量增和质增的作用机制。得到的结论主要有:一是高技术复杂度中间品进口会加剧一国的中间品进口依赖,该结论在多维度检验中均稳健成立,这一机制不仅有助于高技术中间品先发企业成为制衡全球价值链的链主,还容易导致高技术复杂度中间品后发企业成为全球价值链的被俘获者和尾随者;二是高技术复杂度中间品进口通过抑制制造业的资本积累和科研人员规模扩大来加剧高技术复杂度中间品进口国的中间品进口依赖,中国的制造业和服务业中间品进口技术复杂度远高于自身经济发展水平,这使得中国承受的中间品进口依赖压力可能远高于其他国家;三是高技术复杂度中间品进口是经济量增和质增的重要推动力量,促进经济量增和质增战略与降低中间品进口依赖战略之间存在潜在冲突,这一潜在冲突也证实了中国当前以国内大循环为主体发展战略的科学性和正确性。  相似文献

The business model construct has become attractive to both managers and academics. It reflects how the most important organization's strategic and tactical choices regarding the allocation of resources interact in order to create and capture value. Yet with the growing entrepreneurial complexity, managers often end up pursuing conflicting and even paradoxical strategic goals, thus rendering the business modelling processes more complex, too. Well-known examples are profit versus social value, stakeholder versus company interests, exploration versus exploitation and environmental sustainability versus economic returns. The academic business model literature so far has provided limited insights on how to implement business models beyond a single goal and focused mainly on the initial strategic choice of a business model, ignoring that such salient tensions are often persistent and resurface within the business practice. In this study we leverage paradox theory to investigate how managers of creative firms make tactical choices to accommodate (not solve) salient tensions within their business models, focusing on the domains like services provided, choice of clients, networking and resourcing practices, revenue models and new venture creation. Based on qualitative case study research, we found four integrating and three differentiating decision-making tactics that managers deploy to create both economic and creative value through their business models. Adding to the business model theory, we show how business models are crafted in managerial practices by making tactical decisions to solve conflicts and paradoxes. The results equally enrich the paradox literature by providing for tactical-level approaches toward working through the paradox.  相似文献

Hybrid organizational forms that combine commercial and welfare institutional logics play an increasingly important role in addressing the grand societal challenges we face today. Building on the literatures on hybrid organizations and social business models, we explore the characteristics of social businesses from a business model perspective. This study seeks to better understand the particularities and value drivers of hybrid social purpose in contrast to purely commercial business models. We follow a grounded theory approach and our findings are based on interview data from 17 social business firms. Building on social businesses' identified particularities, we propose four value drivers of social business models: 1) responsible efficiency, 2) impact complementarities, 3) shared values, and 4) integration novelties. We link our findings to the literature, contributing new insights into social businesses models and implications for practitioners.  相似文献

This study investigates the impact of service diversification on the rate and mode of firm growth in professional service firms (PSFs). Drawing on the extant PSF literature, we identify differing views regarding the growth impact of service diversification. Specifically, some scholars suggest that the external client benefits associated with service diversification should allow PSFs to expand revenues at a rapid pace and pursue less merger and acquisition activity, whereas others imply that increased diversification can cause internal challenges with respect to learning costs, coordination and innovation that can limit the rate of revenue growth and encourage more mergers and acquisitions. We test these competing views using longitudinal data on 137 accounting firms and cross-sectional data on 125 law firms and find that service diversification is negatively associated with the rate of firm revenue growth and positively associated with the use of mergers and acquisitions.  相似文献

This paper researches productivity in relation to domain complexity and the present knowledge capacity in an organisational context. The study is based on five very different case studies. Three studies are conducted in Denmark, Germany, Mexico and China and are related to knowledge transfer in the relocation of manufacturing facilities. Two studies investigate operation and automation of oil and gas production in the North Sea. The case study method involves semi-structured interviews, surveys, an analysis of historical production data and observations. Based on the findings from the field studies, the paper develops a conceptual framework that management can use for discussions of productivity, development of knowledge and design of learning programmes when considering changes in the complexity of a domain or a change in knowledge.  相似文献

How does servant leaders' unique ability to place each follower's needs above their own influence relationships between followers and impact their collective performance? In a study that integrates principles of servant leadership with the social comparison theoretical framework, we tested a group-level model to examine how servant leadership induces low perceived differentiation in leader-member relationship quality (perceived LMX differentiation) within a group, which strengthens team cohesion and in turn positively influences team task performance and service-oriented organizational citizenship behaviors (service OCB). Our sample comprised 229 employees nested in 67 work teams. Structural equation modeling results indicate that servant leadership significantly predicts low perceived LMX differentiation; perceived LMX differentiation is strongly related to team cohesion such that the lower the perceived differentiation, the stronger the team's cohesiveness. And, team cohesion is also strongly related to both the team's task performance and service OCB. Perceived LMX differentiation and team cohesion mediate the effect of servant leadership on both team task performance and service OCB.  相似文献

Business Modelling has evolved as a key activity to reflect new business venture strategy by framing the way a firm will operate and how it will function in achieving its goals (e.g., profitability, growth, innovation, social impact). However, scholars and practitioners have criticized the adoption of a too static perspective in the design and use of conventional Business Model representations. Such a static perspective prevents nascent entrepreneurs experimenting with their Business Models and, as a result, identifying the most effective strategies, especially in terms of business sustainability and profitability. In this paper, we argue that combining conventional Business Model schemas with System Dynamics modelling results in a strategy design tool that may overcome several limitations related to a static view of Business Model representation. Mapping the different key elements underlying value creation processes into a system of causal interdependencies – through the use of simulation – allows strategy analysts and entrepreneurs to experiment and learn how the business reacts to strategic and organizational changes in terms of performance, innovation and value creation. As such, Dynamic Business Models provide useful insights to strategy formulation and business venturing by capturing how critical Business Model elements interact to produce enduring competitive advantages over time.  相似文献

Regulatory agencies have long adopted a three‐tier framework for risk assessment. We build on this structure to propose a tiered approach for resilience assessment that can be integrated into the existing regulatory processes. Comprehensive approaches to assessing resilience at appropriate and operational scales, reconciling analytical complexity as needed with stakeholder needs and resources available, and ultimately creating actionable recommendations to enhance resilience are still lacking. Our proposed framework consists of tiers by which analysts can select resilience assessment and decision support tools to inform associated management actions relative to the scope and urgency of the risk and the capacity of resource managers to improve system resilience. The resilience management framework proposed is not intended to supplant either risk management or the many existing efforts of resilience quantification method development, but instead provide a guide to selecting tools that are appropriate for the given analytic need. The goal of this tiered approach is to intentionally parallel the tiered approach used in regulatory contexts so that resilience assessment might be more easily and quickly integrated into existing structures and with existing policies.  相似文献
