Given that the possession of abundant resources does not always guarantee superior firm performance, this study proposes a dynamic approach to enhancing firm value. Building on the resource orchestration thesis, we investigate how firms facing resource constraints enhance their capabilities over time by orchestrating resources and how this resource orchestration can play a role in improving firm performance. Using the dynamic perspective, this study identifies four resource orchestration modes, which are specified based on how a given firm dynamically allocates its resources to technology (enacted by R&D activities) and marketing (enacted by advertising activities). Accordingly, we claim that firms with resource constraints can enhance their performance by escalating or altering their resources over time. To test our hypotheses, we used a sample of 4078 small and medium-sized enterprises in manufacturing industries between 1984 and 2018. We found that focus escalation for technology positively affects firm performance, captured by Tobin's q, and that focus alternation toward either technology or market is positively related to firm performance. Finally, we discuss the theoretical and practical implications of our findings.  相似文献

Poor quality of care may have a detrimental effect on access and take-up and can become a serious barrier to the universality of health services. This consideration is of particular interest in view of the fact that health systems in many countries must address a growing public-sector deficit and respond to increasing pressures due to COVID-19 and aging population, among other factors. In line with a rapidly emerging literature, we focus on patient satisfaction as a proxy for quality of health care. Drawing on rich longitudinal and cross-sectional data for Spain and multilevel estimation techniques, we show that in addition to individual level differences, policy levers (such as public health spending and the patient-doctor ratio, in particular) exert a considerable influence on the quality of a health care system. Our results suggest that policymakers seeking to enhance the quality of care should be cautious when compromising the level of health resources, and in particular, health personnel, as a response to economic downturns in a sector that traditionally had insufficient human resources in many countries, which have become even more evident in the light of the current health crisis. Additionally, we provide evidence that the increasing reliance on the private health sector may be indicative of inefficiencies in the public system and/or the existence of features of private insurance which are deemed important by patients.  相似文献

在我国加快实施创新驱动发展战略中,如何提升企业组织创造力以促使企业创新变得至关重要。企业战略是影响组织创造力和创新的重要情境因素。市场导向和创业导向是新兴经济体国家的企业发展的战略核心。然而,现有研究对市场导向与企业创造性产出之间关系的观点却不一致。创业导向如何影响市场导向对组织创造力的作用也尚未得到关注和研究。本研究以145家企业的979份高层管理人员与核心员工的套问卷数据为样本,研究发现:市场导向对组织创造力产生倒U型影响,且倒U型影响通过二元结构文化(一致性文化与适应性文化)的不同传导机制而产生,即:一致性文化在市场导向与组织创造力之间正向中介效应随市场导向的增强而减弱,并在高度市场导向时转变为负向中介效应,而适应性文化在市场导向和组织创造力之间发挥部分中介效应。研究还发现:市场导向对组织创造力的倒U型影响受创业导向的调节作用,即:当创业导向较高时,市场导向对组织创造力的积极影响随市场导向的增强而逐渐增强,反之,则逐渐减弱。研究结论为提升企业组织创造力提供新的思路和理论参考。  相似文献

Research on firm search stresses the need for firms to adapt and align concurrently with their environment to optimize the ability to sense and seize opportunities for sustained performance. We postulate resource scarcity as an important contingency factor for the search-performance relationship, and assess its joint influence with high and low dynamism. Using a dataset spanning 23 years, we examine the performance implications of combinations of internal and external exploratory and exploitative search in resource-scarce environments, under conditions of high and low dynamism. We find that resource scarcity is an important condition for performance stemming from exploratory and exploitative search: even under conditions that involve low dynamism, but joined with resource scarcity, firms may benefit from pursuing exploratory and exploitative knowledge simultaneously.  相似文献

本文选取1435家A股上市公司2011—2018年度的面板数据,以企业金融化水平作为门限变量,研究企业研发投入对企业绩效的非线性影响关系。研究结果表明:(1)企业金融化行为给研发投入对企业绩效的促进作用带来严重的时滞效应,研发投入对当年企业绩效不存在促进作用;(2)研发投入对未来一年企业绩效有双门限效应,二者呈倒N型关系,在第二区间内研发投入促进未来一年企业绩效;研发投入对未来二年企业绩效有单门限效应,在第一区间内研发投入促进未来二年企业绩效;(3)在适度的企业金融化水平区间内,研发投入才会促进未来企业绩效。本文指出上市公司金融化水平最优区间占比分布具有区域、行业和企业性质异质性,并进一步基于实证研究结果提出了相应的政策建议,有利于企业合理管理研发投入和防止企业脱实向虚。  相似文献

The paper examines to what extent a player's market value depends on his skills. Therefore, a data set covering 28 performance measures and the market values of about 493 players from 1. and 2. German Bundesliga is analysed. Applying robust analysis techniques, we are able to robustly estimate market values of soccer players. The results show (1) that there are significantly underrated and overrated players and (2) that a player's affiliation to a certain team may contribute to his market value. We conclude that a club's reputation affects the market values of its players and that star players are in tendency overrated.  相似文献

后发企业技术追赶研究逐渐深入到微观认知基础,但关于管理认知如何驱动技术追赶的机制尚未被充分揭示。通过纵向案例研究,揭示了后发企业高管认知与资源编排动态适配以实现技术追赶的过程。研究发现,在追赶阶段,高管分析型认知通过“纵向资源结构化、稳定性重组、联盟撬动”的资源编排方式进行基本技术积累;在转型阶段,高管创造型认知通过“横向资源结构化、丰富性重组、国际撬动”的资源编排方式获得了新兴技术能力;在超越追赶阶段,高管的悖论型认知通过“双向资源结构化、开拓性重组、平台撬动”的资源编排方式实现了行业技术领先。研究结论既从管理认知视角拓展了技术追赶理论,又为后发企业的追赶实践提供了管理启示。  相似文献

This paper contributes to studies on dynamic capabilities (DCs) by showing that a neglected environmental contingency – i.e. the occurrence of a jolt – shapes the DCs–performance relationship. We focus on high-tech entrepreneurial ventures because these are the firms that jolts affect most; in so doing, we also advance the understanding of DCs in the entrepreneurship field. We argue that, in the aftermath of an environmental jolt, the high-tech entrepreneurial ventures that use internationalization and new product development capabilities to modify their resource configuration and regain environmental fit enjoy better performance. Econometric estimates on a sample of 340 Italian high-tech entrepreneurial ventures confronting the consequences of the global economic crisis that began in 2008 confirm that separately using these two DCs has a positive performance effect. This effect is stronger for relatively smaller ventures. Interestingly, despite synergies should arise from the combined use of the two DCs, we do not detect any superadditive effects.  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

We investigate the possibility of regulatory institutional distance exerting an asymmetric effect on multinational corporations' (MNCs') subsidiary performance depending on the direction of institutional distance. We use the term ‘institutional ladder’ to differentiate between upward distance, referred to as when the subsidiary is operating in a relatively stronger institutional environment than its parent-firm's home country, and downward distance for vice versa. Combining institutional theory with organisational imprinting and learning perspectives, we argue that the implications of regulatory institutional distance on subsidiary performance are relatively more positive (or less negative) when MNCs are climbing down the institutional ladder as compared to when MNCs are climbing up the institutional ladder. We also argue that subsidiary ownership strategy – i.e. the choice of a wholly owned subsidiary (WOS) versus joint venture (JV) – moderates the above-mentioned implications of institutional distance on subsidiary performance. We test these hypotheses based on a panel data-set of 1936 foreign subsidiaries representing 70 host countries and 66 home countries and spanning the 12-year period: 2002–2013.  相似文献
