IT投资的"生产力悖论"研究 总被引：2，自引：0，他引：2
近二十年来，在有关信息技术的研究问题中，“生产力悖论”是研究的焦点之一。本文从宏观经济层面、行业层面和公司层面这三个角度，对有关“生产力悖论”的研究进行梳理和探讨，并对我国的IT投资提出几点启示。 相似文献

2002年Cording提出并购价值悖论,引起了学界对此命题的关注与研究热潮。本文借鉴社会冲突理论,对并购交易过程中管理者与股东之间冲突行为进行理论建模,通过模型分析得出冲突行为如何影响并购价值创造的作用机制。结论如下：在公司并购过程中,管理者可能会选择冲突,也可能选择合作。这主要由并购规模、激励水平、社会保护力量和冲突技术水平等因素决定。一般地,并购规模越大,管理者更倾向选择冲突。此外,激励水平越高、社会保护力量越强和股东的冲突技术水平越高,管理者越倾向选择合作。并购交易中管理者与股东的冲突模型较好地解释了现实中为什么有些并购交易能够创造价值而有些并购交易却损毁公司价值,为解释并购价值悖论现象提供了一个新的视角。 相似文献

全球生产网络效应、集群封闭性及其“升级悖论”——基于大陆台商笔记本电脑产业集群的分析 总被引：14，自引：0，他引：14
全球生产网络中战略隔绝机制的存在,使得依托跨国公司战略空间集聚效应所形成的产业集群具有内在的封闭性,由此导致当地集群的“升级悖论”:集群内企业沿某一特定产品—技术路径升级越快,当地根植性与当地产业关联被弱化的可能性也就越大。本文进一步以大陆台商笔记本电脑产业集群为例,对战略隔绝机制所产生的特定影响及其现实意义作了说明。 相似文献

Serious concerns have been raised that false positive findings are widespread in empirical research in business disciplines. This is largely because researchers almost exclusively adopt the ‘p‐value less than 0.05’ criterion for statistical significance; and they are often not fully aware of large‐sample biases which can potentially mislead their research outcomes. This paper proposes that a statistical toolbox (rather than a single hammer) be used in empirical research, which offers researchers a range of statistical instruments, including a range of alternatives to the p‐value criterion such as the Bayesian methods, optimal significance level, sample size selection, equivalence testing and exploratory data analyses. It is found that the positive results obtained under the p‐value criterion cannot stand, when the toolbox is applied to three notable studies in finance. 相似文献

Empirical Bayes methods of estimating the local false discovery rate (LFDR) by maximum likelihood estimation (MLE), originally developed for large numbers of comparisons, are applied to a single comparison. Specifically, when assuming a lower bound on the mixing proportion of true null hypotheses, the LFDR MLE can yield reliable hypothesis tests and confidence intervals given as few as one comparison. Simulations indicate that constrained LFDR MLEs perform markedly better than conventional methods, both in testing and in confidence intervals, for high values of the mixing proportion, but not for low values. (A decision‐theoretic interpretation of the confidence distribution made those comparisons possible.) In conclusion, the constrained LFDR estimators and the resulting effect‐size interval estimates are not only effective multiple comparison procedures but also they might replace p‐values and confidence intervals more generally. The new methodology is illustrated with the analysis of proteomics data. 相似文献

Resource misallocation, as an essential characteristic of China’s “progressive reform,” has become a significant factor restricting high-quality outward foreign direct investment (OFDI). Using the Database of Chinese Industrial Enterprises (2009–2013), this paper empirically analyzes the impact of resource misallocation on OFDI and its heterogeneous characteristics via the Heckman two-stage selection model. This study finds that total factor productivity has a positive influence on expanding investment quantity. In addition, from the perspective of resource misallocation, factor price distortion inhibits the role of productivity in increasing investment propensity. A mechanism analysis indicates that there is no “productivity paradox” in the decision-making process of OFDI in China as a whole; but there may be an investment productivity paradox in foreign-funded enterprises, enterprises in coastal areas, and large-scale enterprises. After controlling for factor price distortions, the productivity paradox disappears. Thus, total factor productivity (TFP) becomes an important factor in promoting OFDI propensity of overseas-funded enterprises, enterprises in coastal areas and large-scale enterprises. 相似文献

We contend that the development of sustainable supply chain management (SSCM) theory has been impaired by a lack of paradigmatic diversity in the field. The contested nature of the concept of sustainability has been repressed in SSCM theory, which has led to SSCM cutting itself off from debates that could be the source of inspiration for the development of interesting theory. We adopt the problematization approach proposed by Alvesson and Sandberg (2011) in order to unveil some of SSCM's unquestioned assumptions, propose an alternative assumption ground, and in this way move toward stronger theory in SSCM. We use paradoxical framing to make sense of the inherent tensions between the different levels of sustainability and between the different types of theory being produced in response to the challenges of sustainability. We articulate a number of foundational assumptions for an alternative theory of SSCM that emerge from the various tensions identified between the different paradigms of sustainability. Finally, we identify a number of ideas for future research that would enable researchers to empirically explore the alternative assumptions. 相似文献

This study formulates a method to measure the effects of standardization to assist in evaluating innovation and R&D policies. Its main purpose is to examine standardization activities within R&D organizations. This allows for a more appropriate policy evaluation framework than examining such activities within standard development organizations does. The study also redefines the conventional notion of intellectual property (IP) normatively and introduces the term “integrated IP” to reflect our new concept of joining IP and standardization activities. Our new concept captures the “fuzzy” impact of standardization on R&D to improve innovation management. The study presents a vector equation expressing the new IP definition and uses it to model revenues arising from a standard-essential patent for strategic IP management with standardization. The model indicates the importance of patents commercially required for product differentiation for the purpose of innovation with standards. 相似文献

This study examines whether the use of appeals in advertisements can be attributed to cultural practices or values. A convenience sample and a survey method were used to collect data from professionals and students living in Finland. Results show that in Finland cultural practices are more hierarchical and masculine than Hofstede's cultural values. Furthermore, advertisers use significantly more high power distance and masculinity appeals than low power distance and feminine appeals. These frequently used appeals are associated with cultural practices rather than cultural values. These findings suggest that due to the value paradox, cultural practices explain the reflection of culture in advertising. 相似文献
