基于项目管理成熟度模型的创新工程质量目标控制研究

工程质量管理是目前工程管理领域十分重要的板块,特别是创新工程项目.但新的工程质量问题的出现使得原有的方法难以奏效,阻碍了创新工程质量管理水平的提高.在梳理以往质量管理研究的基础上,基于项目管理成熟度模型,提出以费用和工期为约束条件的工程质量控制模型,借助该模型思想,运用历史数据验证降低质量不达标概率.该模型使用了动态规划求解,同时通过算例,验证了该模型的有效性,能够在一定程度上优化质量控制.     

Do Prior Experiences of Top Executives Enable or Hinder Product Market Entry?

How firms achieve entry into new‐to‐the‐firm product markets is an important but overlooked topic. Some aspiring entrants fail during product development, and they miss the opportunity to enter. In such contexts, firms often take action to de‐risk entry, for example, by drawing upon the experience of top executives with market‐specific expertise obtained in prior jobs. However, the empirical evidence from this study shows that beyond a narrow threshold, greater prior experience in the top executive team was associated with a greater likelihood of failed entry attempts among the firms that I tracked over two decades in the biotechnology industry. This result held across product markets with low and high degrees of dynamism. Based on the literature on dynamic managerial capabilities, where entry into new markets indicates managers’ ability to reconfigure organizational resources and adapt to a changing environment, this study’s main contribution is to illustrate how and why experience matters for entry.     

Stunting and academic achievement among Vietnamese children: new evidence from the young lives survey

Most of the empirical literature on the relationship between the health condition and skill development of school children are based on a static relationship between health and skill development. This article contributes to the literature by examining the dynamic relationship between stunting and school achievement using data from the first three waves of the Young Lives Survey in Vietnam. Using both structural equation and hybrid estimators, empirical results show that past school performance is the most significant predictor of the academic performance. Stunting has a significant negative effect on school performance, and its effect in the long run is as twice as much its effect in the short run. The empirical evidence also shows that the age of the child, mothers’ literacy, access to electricity and household consumption significantly affect school performance.     

From less promising to green? Technological opportunities and their role in (green) ICT innovation

This article aims to shed light on the role of technological opportunities for green innovation by studying the case of Green ICT innovation. We test whether firms active in low-opportunity technological areas are less likely to be innovative and whether they are more likely to change their direction of technical change. To do so, we construct a firm-level panel data set for the years 1992–2009 combining patent data from the European Patent Office with firm-level data from the German Innovation Panel (Mannheim Innovation Panel). The results are based on dynamic count data estimation models applying General Methods of Moments estimators. Our results support our hypotheses: firms active in low-opportunity technological areas are less innovative but are more likely to switch from pure ICT innovation to Green ICT innovation.     

Climate change implications for the catastrophe bonds market: An empirical analysis

Since their introduction in the mid-1990s, the return per unit of risk or multiple on catastrophe (cat) bonds has steadily declined. This paper investigates whether this pattern is consistent with the historical evolution of natural disaster risk, using average multiple figures over the period 1997–2017. Assessing the accuracy of cat bond pricing is important, since about 50% of outstanding risk capital in the cat bonds market is currently exposed to Atlantic hurricanes -a risk that global warming, among other disruptions, is found to enhance- and pension and mutual funds in European and other OECD countries currently own about 30% of the market. In this respect, while our findings suggest that falling multiples are primarily related to the Fed's expansionary monetary stance and to portfolio shift effects, we do also find evidence of significant undervaluation of global warming risk in the cat bonds market. This finding, also in light of the unfailing appetite of institutional investors for such securities, casts doubts over the sanity of the market and over cat bonds as suitable investment products for risk averse investors. Sounder investment opportunities might be found in the green bonds market, which allows for the funding of immediate investment in climate change mitigation too.

中国FDI区位决定因素研究(1986—2009)

关于中国和其他经济体的外商直接投资(FDI)区位决定,绝大部分研究仅仅关注决定因素的选择,而忽略了决定因素及其重要性可能会随一个国家或地区FDI的特性的变化而变化。而且,这类研究也几乎不考虑空间数据的特征。文章以中国为对象,顾及省域变量的空间特征,采用空间面板数据分析方法,并通过分阶段方式来捕捉FDI决定因素及其重要性,研究结果表明,空间特征确实在中国省域引进FDI中具有影响作用,FDI决定因素及其重要性会随时期动态变化。上述发现对中国各级政府以及跨国公司都具有重要政策和决策意义。     

关于公路桥头搭板的试验与检测

桥头搭板是一端简支在桥台上,另一端搁置在桥头引道路基或者路面结构材料上的钢筋混凝土板。拟对高速公路通道桥两端桥头搭板进行了试验与研究,其中静载试验荷载作用下搭板底面对路基产生压力大小,以便判断是否有脱空即脱空位置,动载试验内容动载试验是对通道桥头搭板的动力特性以及汽车荷载作用下的动力响应进行试验研究,并评价行车舒适性。本文通过对高速公路桥头搭板静载和动载试验进行研究,对桥头搭板的结构形式的合理性,以及试验桥头的行车舒适性进行分析。     

领导者二面能力演化的企业动态创新能力——理论与案例研究

已有二面能力研究多从组织层面分析它对实力较强企业发展的重要影响。可是,二面能力能否为落后的企业注入创新活力,改变其发展窘境是本文研究的重点问题。为此,本研究从个体层面的领导者二面能力入手,围绕某个省级合作金融机构的系统开发过程典型案例,从功能设计、软件开发和上线推广三个环节详细分析领导者通过不断识别、把握和重构将二面能力向企业动态创新能力的演化过程,验证了领导者二面能力对落后企业发展的重要性。
