提出产业技术竞争优势的概念,并探讨其"规模-质量-价值"三维模型和测度指标体系;构建产业技术竞争优势指数,利用熵值法设置权重,采用合成指数法计算产业技术竞争优势指数。以世界生物医药产业主要国家(中、美、德、日)1996-2016年样本数据进行实证研究。结果表明:中国生物医药产业技术竞争优势指数及分指数总体保持上升趋势,其中规模指数增长较快,价值指数次之,质量指数发展居于末位;美国、日本和德国竞争优势指数相近,均具有较强的竞争优势;中国产业技术竞争能力处于劣势地位,规模维度方面中国与其它三国差距较小,价值维度差距次之,质量维度差距较大。  相似文献

Data Envelopment Analysis (DEA) window analysis with ideal window width is applied to evaluate the green technology innovation efficiency of 28 manufacturing industries in China during 2006–2014. The obtained results are compared with those calculated using the traditional DEA model, and convergence analysis of the efficiency is conducted. Five years is the obtained ideal window width and DEA window analysis with ideal window produces results closer to reality for China's manufacturing industry. The overall efficiency of the green technology innovation in the manufacturing sector is low following a wave-shaped curve – first decreasing, then increasing and decreasing again, with large inter-industrial differences. There are 8 high-, 14 medium- and 6 low-efficiency industries. A convergence trend in the green technology innovation efficiency within the 28 manufacturing industries exists, implying a catch-up effect between them.  相似文献

This article examines the role of small- and medium-sized multinational enterprises (MNEs) in the dynamic development of global production networks (GPNs) in the maritime industry. It studies the dynamism between subsidiaries of Norwegian maritime firms and regional actors and institutions in the Greater Shanghai Region of China from the perspectives of the subsidiaries. It argues that strategic coupling, recoupling and decoupling are partly the results of regional selection mechanisms. However, in the cases where the subsidiaries are embedded within the host region, the strategies and behaviour of MNEs are of decisive importance for the dynamic development of GPNs.  相似文献

Each year, clients spend large sums on professional services, such as accounting services, legal services and consulting services. While research has found significant cross-country differences in organizations’ spending on professional services, we do not know why they occur. Inspired by the organizational buying behavior literature, this paper investigates the influence of national culture on the use of professional services, particularly management consulting services. As the use of professional services involves considerable uncertainties—particularly for the buyer—it can be assumed to be influenced by cultural differences regarding the level of Uncertainty Avoidance, Individualism and Masculinity. By drawing on two independent cross-country studies, we show that organizations in high uncertainty avoidance and individualistic cultures use professional services less than organizations in low uncertainty avoidance and collectivist cultures. We found no relationship between Hofstede's dimension of Masculinity and the use of professional services. The findings contribute to the theorizing on how the cultural context influences organizational buying behavior and the purchasing of professional services.  相似文献

Drawing on Denison and Mishra (1995)’s framework of organizational culture, this study examines why and when organizational culture is related to knowledge workers’ affective commitment. Data were collected from 640 employees working in three high-technology companies in China. The findings indicate that the relationship between organizational culture and affective commitment is mediated by perceived psychological contract fulfilment. In addition, organizational tenure moderates the relationship between two external dimensions (i.e. adaptability and mission) of organizational culture and perceived psychological contract fulfilment. This study extends the current theoretical framework of organizational culture by demonstrating the underlying mechanism and the boundary condition of the relationship between organizational culture and affective commitment. The findings also provide practical implications for international managers to design appropriate human resource management policies and practices in China.  相似文献

Real options (RO) valuation has been promoted as a way to evaluate investment opportunities and make investment decisions that takes into account the value of managerial flexibility in the face of uncertainty. Although RO enjoys a substantial body of literature considering its application and suitability in different situations, the impact of national culture on the application of RO has received little attention. Values embedded in national culture affect the behavior of managers. In particular, these values play a role in how managers frame information, communicate, and make decisions, directly and indirectly affecting behavior through cultural layers such as organizational culture. National culture, therefore, can systematically affect the application of RO, potentially leading to suboptimal outcomes. In this article, we hypothesize how 2 particularly relevant dimensions of culture, power distance and uncertainty avoidance, affect RO exercise, and estimate the magnitude suboptimality of these effects using a model we develop for the case of a put option. Our estimates suggest RO may not always be a superior valuation approach to net present value for national cultures with certain characteristics.  相似文献

This article examines the role of national culture, measured by conflict avoidance, on the relationship between leader–member exchange (LMX) and individual employee voice. Using data collected from automotive industry employees in the United States and Korea, the findings show that conflict avoidance is negatively related to employee voice and also moderates the relationship between LMX and employee voice in the Korean sample. In particular, the relationship between LMX and voice becomes less positive when conflict avoidance is high. On the other hand, conflict avoidance does not have a direct effect on employee voice as well as an interactive effect with LMX on employee voice in the U.S. sample. This study, therefore, highlights the importance of the national culture in the comparative study of employee voice.  相似文献

We examine the efficacy of government regulation on a firm's product. We draw on the behavioural approach of organization research in order to understand the micromechanisms whereby the regulatory intervention process affects corporate operation. We suggest that while government investigations may limit the improvements in product quality by distracting a firm's attention, this unintended outcome depends on the extent to which the firm engages in a substantive problem‐solving process with the regulator during an investigation process. A longitudinal analysis of the US government's investigation into motor vehicle engine production offers overall support for our argument. The paper concludes with a discussion of the implications that our findings present to learning theory and institutional literature. Copyright © 2017 ASAC.

为了探究创新驱动产业转型升级的作用机制,构建了创新投入与创新产出对产业转型升级内涵质量与外显效应的影响模型,并提出研究假设。基于中国1998-2016年省域面板数据,借助Eviews 9.0计量软件,采用固定效应模型进行实证研究。结果表明,所提出的研究假设均得到验证。创新产出对产业转型升级内涵质量具有积极影响,创新产出的各表征变量(专利授权数、技术市场合同成交金额、新产品销售收入)每增长1%,产业转型升级内涵质量的表征变量人均国内生产总值将提高0.014 8%~0.051 1%。创新投入对产业转型升级外显效应具有积极影响,创新投入的各表征变量(R&D经费内部支出、R&D人员全时当量)每增加1%,产业转型升级外显效应的表征变量产业结构层次系数将提高0.007 1%~0.010 5%。因此,创新能够驱动产业转型升级,但创新投入与创新产出对产业转型升级的影响机制并不相同。研究结果为创新驱动产业转型升级问题的研究提供了一个新的研究范式,对实施创新驱动发展战略、促进产业转型升级有借鉴意义。  相似文献
