从绿色建筑供给侧角度出发,构建消费者效用函数、开发商利润函数和政府与开发商的演化博弈模型,分析消费者绿色偏好、建筑绿色度、成本等因素对建筑价格、需求和利润的影响以及政府动态奖惩政策下系统的演化稳定策略。结果表明:消费者绿色偏好支付系数和建筑绿色度的增大有利于绿色建筑价格、需求和利润的提高,但高成本却使需求和利润降低;政府采用静态补贴与静态税收政策时,博弈系统不存在演化稳定策略,采用动态补贴与静态税收、静态补贴与动态税收、动态补贴与动态税收三种政策组合时,系统存在演化稳定策略;动态补贴与静态税收的政策组合在推动绿色建筑发展方面优于其他政策;开发商开发绿色建筑的概率与补贴上限值呈负相关,与税收上限值呈正相关。  相似文献

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

Building on recent efforts to bring a socio-political perspective to social capital research, we develop and test a multilevel framework that explains why middle managers who occupy brokerage positions differ in their ability and willingness to engage in entrepreneurial behavior. More specifically, we provide a contextualized understanding of the links among middle managers' brokerage, their political-support ties, and their personal initiative. Results derived from data on 383 middle managers and 72 top managers in 34 business units indicate that political-support ties with top managers strengthen the relationship between middle managers’ brokerage and personal initiative. However, this positive effect depends on the social capital resources available in the focal business unit. It is attenuated in business units with a supportive and trusting social context and amplified in business units with high levels of internal connectedness. By uncovering these incompatibilities and complementarities, our study demonstrates the value of accounting for different social capital configurations and the interplay of their inherent social capital resources when examining the effects of brokerage on corporate entrepreneurship.  相似文献

Scholars have highlighted the use of punishment as a tool to defend laws and norms, deter deviance, and restore justice in the aftermath of organizational misconduct. However, current theory and research primarily draw on a micro-oriented lens to understand how punishment occurs in response to deviant actors within organizations, neglecting macro-oriented questions of whether and how organizations are punished for their misconduct. We review sociological and macro-organizational work that suggests punitive severity can vary with three key attributes of the organization: status, reputation, and embedded ties. We then develop a mezzo-lens framework motivated at the intersection of micro- and macro-perspectives on organizational misconduct to shed light on opportunities for theoretical expansion by crossing levels of analysis.  相似文献

We examine both mediation and moderation effects on the direct relationship between internationalization speed and firm performance in the context of small and medium-sized enterprises (SMEs). Building on prior studies that focus either on the direct speed–performance linkage or the moderating role played by knowledge, we suggest that an important source of performance variations is organizational learning. Grounded in the organizational learning perspective, we argue that firm strategies regarding speed and earliness of internationalization provide the SMEs with opportunities to develop their absorptive capacity, and thus enhance their performance. Using survey data from 343 SMEs in Australia and New Zealand, our empirical results suggest that absorptive capacity is associated with internationalization speed in a reversed U-shape relationship and that in turn absorptive capacity mediates the direct speed–performance relationship. Moreover, this mediating effect is moderated by earliness of internationalization. By demonstrating the moderated mediating effect of absorptive capacity as a novel mechanism to achieving superior performance, we enhance the understanding of how firms succeed internationally.  相似文献

This study examines the effect of board size on the economic impact of bank mergers and acquisitions (M&A) in the US. Using a hand-collected dataset of 508 M&A between 2012 and 2018, we find that board size is negatively related to acquirer excess returns. In an additional analysis, we show that large boards have positive value implications for banks that combine the CEO and chairman roles as well as for large banks. Our findings indicate that a “one-size-fits-all” approach to board size is not necessarily in the interests of shareholders; instead, a more flexible and proactive formulation is needed.  相似文献

There is increasing research attention as to how SMEs might realize corporate social responsibility opportunities. Most studies focus on the pursuance of responsible business strategies that result in favourable business outcomes. This study investigates SMEs who actively participate in CSR activities in a south-eastern European country during the economic crisis of the Eurozone. Data collected reveals that stakeholder salience and proximity moderate the relationship between CSR and financial performance. The context of this study is important as it addresses the paucity of research carried out in countries during economic crisis and sheds light on the positive aspects of CSR practices adopted during crisis.  相似文献

Ecosystems are formed by organisations that jointly create a value proposition that a single firm could not create in isolation. To deliver this value proposition, the partners need a focal firm, the orchestrator, to be align them towards the joint value proposition. Thus, how orchestrators design the alignment structure of an ecosystem is at the very heart of the ecosystem concept – yet it has not been sufficiently addressed by extant research. This is all the more true for the question of how the design of an ecosystem is shaped depending on surrounding conditions. This paper applies a qualitative study with ten cases and, based on the attention-based view of the firm, contributes to research on ecosystems in several ways. First, it explains which ecosystem designs are beneficial under which conditions. Second, it elucidates the structure and activities within ecosystems and shows that start-ups can be just as good ecosystem orchestrators as incumbents. Third, it explains the circumstances under which single vs. multi orchestrator ecosystems occur. Fourth, it presents the conditions when incumbents or start-ups make better orchestrators. Finally, it is among the first studies to apply the attention-based view to business ecosystems, and shows that doing so yields intriguing insights into this emerging field of research.  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

随着绿色发展成为五大发展理念之一,各地政府推进绿色技术创新成为降低环境污染和提高增长质量的主要途径。为了考察地方政府环境分权和竞争对绿色技术创新影响的“本地—邻地”效应,本文利用非期望产出EBM模型测度绿色技术创新程度,并将绿色技术创新指数引入动态空间杜宾模型。最后,结合2003-2017年中国省级面板数据进行实证分析。研究发现:(1)绿色技术创新具有显著的路径依赖、空间集聚以及邻近地区的策略竞争效应;(2)环境分权对本地和邻地绿色技术创新的影响呈“U型”变动特征,且现阶段并未跨越分权驱动创新的临界点;(3)环境分权与地方政府竞争的交互效应整体为负,环境行政分权、环境监察分权和环境监测分权等不同类型环境分权采取的策略并不相同;(4)区域环境分权产生的绿色技术创新激励效应存在异质性,中西部地区环境分权对绿色技术创新的激励效果更强。  相似文献
