创新要素配置在投入产出两个环节中生成大量不完全技术信息,投入产出效率随机变动更加明显。从投入产出数据集合中提炼共同因子,与不可观测变量构成预测器,建立因子增广向量自回归模型(FAVAR),分析随机变动方差构成,测度投入产出效率随机变动程度。随机变动效应包括水平效应、稳定性效应和规模效应。投入产出效率自回归扰动项表示随机变动程度,将其细分为共同因子,计算预测器方差及其与投入产出效率的协方差。基于669家上市公司月度、季度、半年度和年度技术研发数据,比较分析投入产出效率随机变动程度及形成原因,引入脉冲响应法分析变量方差构成与变动特征,提出相关政策建议。  相似文献

The objective of this paper is to contribute to the understanding of the supervisory role of the board of directors in the context of mergers and acquisitions (M&As). We focus our study on the European case, for which there is no previous exhaustive evidence on this topic. Using information on 985 mergers and acquisitions carried out over the period 2003–2016 by companies in the major European countries, we analyze the influence of supervisory capacity of the board (small size, higher proportion of outsiders and separated Chairperson-CEO positions) on acquirer returns, differentiating between Anglo-Saxon and continental European contexts. Our results confirm that the effectiveness of corporate governance practices depends strongly on their fit with the broader institutional context. Specifically, we find that a smaller size of the board of directors and the separation of the positions of Chairperson and CEO lead to higher acquirer returns in European Anglo-Saxon countries. By contrast, we do not find evidence that any proxy of supervisory capacity of the board significantly improves acquirer returns in the rest of countries.  相似文献

This paper discusses the determinants of China’s outward foreign direct investment (OFDI) with a special focus on the role of government policy. In particular, we investigate the types of policies that are most influential in promoting OFDI. Our main contribution is to analyse, for the first time, China’s OFDI policies by means of quantitative indicators. We refine policies definitions and distinguish between Regulation Policies, Service Policies, Promotion Policies and Supervision Policies, and we develop a methodology for collecting, screening and coding policies; then we create new indices to capture different types of policies. We find that Regulation Policies, Service Policies and the general attitude of the government have significant effects on China’s OFDI at the national level.  相似文献

区域创新能力提升是我国加快建设创新型国家、实现高质量发展的现实需求。 本文通过构建涵盖资源依赖、制度安排与区域创新能力的理论模型分析其内在关系并提出假 说,运用2000-2016年全国30个省(区、市)的面板数据与空间杜宾模型,检验三者之间的影 响及空间溢出效应。研究结果表明:(1)资源依赖程度越高,越不利于本地区创新能力提升;(2)有效率的制度安排对区域创新能力有正向促进作用;(3)从空间溢出效应来看,本地区 资源依赖程度越高,越抑制周边地区区域创新能力提升,有效的制度安排能助推周边地区创新能力提高。  相似文献

机构投资者与政府补贴等优惠政策作为企业经营的重要资本来源和制度保障,势必对企业技术创新产生重要影响。以我国沪深两市战略性新兴上市企业2010-2015年面板数据为研究样本,对异质机构持股、政府补贴与企业技术创新的关系进行实证分析。结果发现:机构持股对企业技术创新没有显著影响,政府补贴可以促进机构持股对企业技术创新尤其是实质性技术创新产生显著正向影响;基金持股对企业技术创新存在显著负向影响,券商持股与QFII持股对企业技术创新分别存在不显著和显著正向影响;政府补贴能够降低基金持股对企业技术创新的负向影响,有效促进基金持股对企业技术创新的正向影响,并通过调节作用促进券商持股和QFII持股对企业技术创新产生更加显著的正向效应;政府补贴对基金持股与企业非实质性技术创新关系的正向调节作用更加显著,对券商持股和QFII持股与企业实质性技术创新关系的正向调节作用更加显著。  相似文献

Expected shortfall (ES) is a popular risk measure and plays an important role in risk and portfolio management. Recently, change-point detection of risk measures has been attracting much attention in finance. Based on the self-normalized CUSUM statistic in Fan, Glynn and Pelger (2018) and the Wild Binary Segmentation (WBS) algorithm in Fryzlewicz (2014), this paper proposes a variant WBS procedure to detect and estimate change points of ES in time series. The strengthened Schwarz information criterion is also introduced to determine the number of change points. Monte Carlo simulation studies are conducted to assess the finite-sample performance of our variant WBS procedure about ES in time series. An empirical application is given to illustrate the usefulness of our procedure.  相似文献

Hybrid governance forms that seek to meld the virtues of both market control and traditional hierarchical control are alluring. Comparatively little research, outside of the M-form literature, has examined internal hybrids - hierarchical forms infused with elements of market control. This paper contends that common change initiatives, such as TQM, re-engineering, autonomous work teams, and group-based rewards, are appropriately viewed as attempts to craft internal hybrids by selectively infusing elements of market control within hierarchy. However, these change initiatives are often implemented in isolation and, as a consequence, violate patterns of complementarity that sustain traditional hierarchy or support the stable infusion of market control.The paper argues that these violations of complementarity often spiral hierarchies toward fundamental transformation. The clear trajectory of these transformations is to quite radically disaggregated organizations structured around teams. The paper presents both theory and evidence supporting the existence of complementarities among these common change initiatives.  相似文献

MONEY 2000? is a successful consumer education programme that was implemented by Cooperative Extension personnel in over two dozen states of the USA between 1996 and 2002. One of the unique features of this programme is that it was based on the Transtheoretical Model of Change (TTM), a framework that has been widely used to study health‐related behaviour changes such as smoking cessation. This paper first describes how the MONEY 2000? programme was developed around major constructs contained within the TTM. Findings are reported from a survey conducted with participants in the first two states that delivered the programme. The findings suggest that several change processes used by MONEY 2000? participants are associated with specific stages of change. In addition, there may be differences in behavioural changes between participants who increased their savings and those who reduced their debts.  相似文献

This paper contrasts goal-directed and institutional approaches to the development of performance measurement (PM) in the Swedish university sector, which has been subject to increasing emphasis on management by objectives since the early 1990s. We adopt a macro perspective, focusing on recent changes in PM related to governmental control of universities and colleges and combine an extensive review of archival data with interviews in our empirical analysis. It is concluded that although the goal-directed model cannot be completely rejected as a heuristic informing recent changes in PM, a process-orientated institutional perspective considerably enriches the analysis by making it less static and more contextually informed. In particular, the latter perspective better explains the evolution of loose couplings between formally stated goals and performance indicators and between different systems for PM by directing attention to the complex interplay between conflicting constituent interests in the evolution of resource and cost allocation practices and quality control procedures. However, our empirical analysis also leads us to reconsider the conceptions of loose coupling as either a “given” feature of institutionalised organizations or an outcome of more pro-active resistance at the micro level prevailing in much earlier work in institutional theory.  相似文献
