How open search strategies align with firms’ radical and incremental innovation: evidence from China

The purpose of this paper is to describe the ways in which open search strategies (i.e. open search breadth and open search depth) align with firms’ radical and incremental innovation. By analysing survey data collected from 162 firms in Chinese high-tech markets, we found that a firm pursuing radical innovation benefits more from open search breadth than open search depth to achieve its performance goals; in contrast, a firm processing incremental innovation benefits more from open search depth than open search breadth to improve its performance. Based on these results, managers should pay attention to the fit between open search strategies and radical/incremental innovation. This study not only contributes to the studies of search strategies by identifying the parallel relationship of open search strategies and two types of innovation, but also enriches the theory of open innovation with an empirical analysis.

Further results on monopolistic competition,markup pricing and the business cycle in Switzerland

This paper investigates how firms’ market power affects the price level. Based on a small macro-model it is shown empirically that firms have structural markup pricing power and take advantage of favourable business cycle fluctuations. To this aim, a multivariate time series model with double integrated variables is estimated. Thereby a model-based business cycle indicator can be derived. Its information content is confronted with survey data giving rise to what is going to be called semantic cross validation approach.

农产品营销创新方式与营销绩效的关系研究

在全球金融危机逐渐曼延的市场背景下,农产品企业的营销创新尤显重要,文章在文献综述的基础上将营销创新划分为渐进式营销创新、以技术为基础的变革型营销创新、以市场为基础的变革型营销创新三种营销创新方式,并将营销创新的前置变量市场导向划分为市场驱动导向和驱动市场导向,将这些变量与营销绩效一起构建了营销创新理论模型,并以国内191家农产品企业为样本,对模型进行实证检验。研究发现：两种变革型营销创新方式对营销绩效有显著的正向影响,而渐进式营销创新对营销绩效的影响不显著,变革型营销创新在驱动市场导向与营销绩效之间具有重要的中介效应,为二者间关系提供了新的解释。     

国有银行不良资产的评估与控制的初步探讨--统一尺度与增量尺度的结合

不良资产比率是金融监管部门用来评价银行的一个重要指标 ,它同时影响到银行的资本金充足率。我国四大国有商业银行由于历史政策性包袱以及长期转型过程中积累起来的不良资产 ,严重影响了资本充足率的提高 ;且由于各商业银行的历史包袱轻重不一 ,评估过程中既要有统一尺度 ,又要有区别于历史包袱的增量尺度 ,这给金融监管部门带来了极大的不便。本文通过建立数学模型 ,对这一问题的解决进行了研究。     

投资信息审计意见可以提高公司投资效率吗？——基于公司内部治理环境的调节效应

通过手工整理2013—2015年审计报告中的投资事项增量信息,研究审计意见中投资事项增量信息(投资信息审计意见)与公司投资效率之间的关系。结果表明,投资信息审计意见具有缓解投资过度的正面作用,但也具有加剧投资不足的负面作用;内部治理环境具有调节效应,当内部治理环境较好时(代理成本较低、管理层权力较小),投资信息审计意见的正面作用得到提升,负面作用受到抑制。进一步进行中介效应检验发现,内部监督在投资信息审计意见缓解投资过度的过程中起到了中介效应,表明促进股东加强内部监督是投资信息审计意见发挥作用的重要途径。研究结论表明审计意见中与投资事项相关的增量信息具有额外价值。     

耕地非农化风险及增值收益分配机制研究——以哈尔滨市为例

研究目的:探寻合理分配耕地非农化增值收益的方法,从耕地非农化风险角度构建增值收益分配机制。研究方法:联盟利益分配机制,模糊综合评价法。研究结果:在耕地非农化中,各权利主体所担风险从高到低依次为农民、中央政府、地方政府、村集体;假设各权利主体参与征地行为是一种投资行为,各权利主体耕地非农化增值收益分配比例为中央政府占26%,地方政府占22%,村集体占17%,农民占35%;运用"联盟利益分配机制"测算耕地非农化各权利主体之间的增值收益分配比例是可行的。研究结论:以缩小征地范围、尊重农民意愿为条件制定征地补偿标准不仅体现补偿公平原则,也符合通过市场机制对农民进行补偿的改革方向。     

Model selection in toxicity studies

In toxicity studies, model mis‐specification could lead to serious bias or faulty conclusions. As a prelude to subsequent statistical inference, model selection plays a key role in toxicological studies. It is well known that the Bayes factor and the cross‐validation method are useful tools for model selection. However, exact computation of the Bayes factor is usually difficult and sometimes impossible and this may hinder its application. In this paper, we recommend to utilize the simple Schwarz criterion to approximate the Bayes factor for the sake of computational simplicity. To illustrate the importance of model selection in toxicity studies, we consider two real data sets. The first data set comes from a study of dietary fortification with carbonyl iron in which the Bayes factor and the cross‐validation are used to determine the number of sub‐populations in a mixture normal model. The second example involves a developmental toxicity study in which the selection of dose–response functions in a beta‐binomial model is explored.
