Innovation,competition and productivity

We investigate the drivers of firm‐level productivity in catching‐up economies by jointly estimating its relationship to innovation and competition using data from the EBRD‐WB Business Environment and Enterprise Performance Survey (BEEPS) in Eastern Europe and Central Asia. The findings confirm an inverted‐U shaped impact of competition on R&D. Both competition and innovation have a simultaneous positive effect on labour productivity in terms of either sales or value added per employee, as does a high share of university graduates and foreign ownership. Further positive impacts come from firm size, exports or population density. Innovation and foreign ownership appear to be the strongest drivers of multifactor productivity.     

国内同传中的预测研究

这是一篇批判性和反思性的研究综述.预测是同声传译中的重要技巧,已经引起了口译研究者的普遍关注.根据对中国知网文献的检索,国内现有的对预测的研究主要是从认知心理学的角度对预测的机制、策略、作用、价值以及影响因素等方面进行的探讨,其中对预测作为一种口译策略及其工作机制的研究占绝大多数.这些研究文献多为硕士论文,也有少量大学学报论文和普通期刊论文,研究课题的重复率较高.从这一情况可以看出,目前国内对于同传中预测的研究在研究的深度和系统性方面亟待提高.运用不同的口译研究范式对预测问题进行深入研究,对提高口译学习者和教学者对该问题的认识,提高训练和教学效果具有指导意义.     

工业技术发展战略选择与中国宏观经济增长——基于宏观协整计量经济模型的实证

文章以协整理论为基础,建立了一个能够反映我国大中型工业企业技术创新活动与宏观经济增长相互联系的小型宏观协整计量经济模型,以大中型工业企业创新投入为政策变量,以国内生产总值为目标变量,模拟运行不同方案下GDP的波动情况。结果表明,大中型工业企业创新投入对GDP的影响依次为:技术改造投入、R&D投入、国内技术购买及国外技术引进;创新投入在宏观经济中都有其内在的联系机制,只有保持一定的比例关系它们才能对宏观经济增长发挥更大作用。结论对当前我国工业技术发展战略的正确定位具有一定参考意义。     

改良型A~2O工艺同步脱氮除磷试验研究

采用改良型A2O工艺进行同步脱氮除磷试验,表明改良型A2/O通过连续进水方式也可以驯化富集出反硝化聚磷菌,并且通过试验表明其中氧和NO-3-N为电子受体时的同步脱氮除磷效率要高于NO-2-N为电子受体时的情况,系统最终磷处理效果受进水的C源影响很大。     

Fee-for-service payments and consultation length in general practice: a work–leisure trade-off model for French GPs

This article presents an adaptation of the labour supply model applied to the independent medical sector. First, we model simultaneous General Practitioner (GP) decisions on both the leisure time and the consultation length for two payment schemes: fixed fees and unregulated fees. The objective of this econometric study is to validate the theoretical prediction that doctors under unregulated fees may make choices about the length of patient consultations independent of their personal leisure decision. Indeed, according to our empirical results, the bidirectional link between leisure choice and consultation length – verified with fixed fees – does not hold any longer under unregulated fees. Our findings can be seen as a necessary but not a sufficient condition to legitimize unregulated fees in general practice.     

Cost Efficiency and the Choice of Operation Type: Evidence from Taiwan's International Tourist Hotels

This study investigated the endogenous relationship between the differences in cost efficiency and hotel owners' choices of either remaining an independently operated establishment or joining an international chain. We applied observations of 72 international tourist hotels in Taiwan from 1997 to 2008 to a simultaneous equations model with qualitative and limited dependent variables. The study results suggest that joining international chains significantly improves cost efficiency. We also found that net gains from improving both cost efficiency and hotel location are the two foremost determinants for an owner's decision to join an international hotel chain.     

The Influence of Legal Capacity on WTO Dispute Duration

World Trade Organization dispute settlement has evolved away from the concise process originally imagined to one where panels languish for years. This is to the detriment of lesser-developed states that do not have the resources that allow for access. In this article, I perform a multivariate analysis to explore the relationship between a state's legal capacity and the length of trade disputes. Controlling for selection bias, I find that the legal capacity of both of the involved parties contributes to longer disputes. The relaxed time expectations in this process favor the inclusion of developed states and exclude those without the resources necessary to carry out what has become the normal dispute process.     

预曝气—水解酸化-硝化反硝化工艺处理明胶生产废水

采用预曝气—水解酸化-硝化反硝化工艺处理明胶生产废水,水解工艺对进水悬浮物去除效果和有机氮的氨化作用明显,硝化反硝化可将水解产生的NH3—N全部转化。实际运行结果表明,在进水COD为2500mg/L、氨氮为200mg/L的情况下,系统出水COD<60mg/L,氨氮<10mg/L,达到了《污水综合排放标准》(GB 8978-1996)的一级标准。     

大众传媒中的同声传译质量评估

对美国总统奥巴马的就职演说中国中央电视台和凤凰网都进行了直播,并分别配以汉语同声传译。从这两个同声传译案例中,可以看出同声传译在大众传媒中的工作特点、质量状况和改善策略。     

上市公司融资行为与市场价值相互关系的实证研究

本文建立了以债务融资率、股权再融资率和市场价值为系统内生变量的结构方程,对我国上市公司的数据进行实证分析。结果表明,股权再融资率与债务融资率之间存在显著的正相关关系;债务融资率与市场价值之间存在显著的负相关关系;市场价值对股权再融资率有显著的正的影响,而股权再融资率对市场价值有显著的负的影响。本文对这些关系进行了分析,并与单方程的检验结果进行比较,表明单方程估计会导致忽略某些重要的因素。
