企业知识类型及其相关研究

随着知识经济的兴起,知识管理受到越来越广泛的关注。作为提高企业核心竞争能能力的重要资源,隐性知识愈发显示其重要性。本文介绍了显性知识与隐性知识的研究现状,分析了现阶段隐性知识研究存在的问题,最后从组织管理、隐性知识交流环境、员工隐性知识挖掘、隐性知识传播等宏观和微观两个方面提出了隐性知识研究中存在问题的解决办法。     

以社会主义核心价值观引领高校基层党组织建设与创新

社会主义核心价值观是“以人为本”的价值观,是建设和谐社会的根本,为社会主义事业指明了方向。高校的创新精神和能力决定着国家的前途,当前高校基层党建中存在一些问题,是与发挥党组织的先锋堡垒作用相背离的,创新高校党建工作机制,是坚持社会主义办学方向的重要保证。本文阐述了高校要以社会主义核心价值观引领基层党组织工作的创新的意义和途径,提出基本思路,并进行有益的实践和探索。     

Does money impede convergence?

Inspired by Clower’s conjecture that the necessity of trading through money in monetised economies might hinder convergence to competitive equilibrium, and hence, for example, cause unemployment, we experimentally investigate behaviour in markets where trading has to be done through money. In order to evaluate the properties of these markets, we compare their behaviour to behaviour in markets without money, where money cannot intervene. As the trading mechanism might be a compounding factor, we investigate two kinds of market mechanism: the double auction, where bids, asks and trades take place in continuous time throughout a trading period; and the clearing house, where bids and asks are placed once in a trading period, and which are then cleared by an aggregating device. We thus have four treatments, the pairwise combinations of non-monetised/monetised trading with double auction/clearing house. We find that: convergence is faster under non-monetised trading, implying that the necessity of using money to facilitate trade hinders convergence; that monetised trading is noisier than non-monetised trading; and that the volume of trade and realised surpluses are higher with the double auction than the clearing house. As far as efficiency is concerned, monetised trading lowers both informational and allocational efficiency, and while the double auction outperforms the clearing house in terms of allocational efficiency, the clearing house is marginally better than the double auction in terms of informational efficiency when trade is through money. Crucially we confirm the conjecture that inspired these experiments: that the necessity to use money in trading hinders convergence to competitive equilibrium, lowers realised trades and surpluses, and hence may cause unemployment.     

新型组合式输尿管软镜治疗肾结石的手术配合

目的：探讨新型组合式输尿管软镜治疗肾结石的手术配合要点及护理。方法对60例肾结石患者采用德国铂立组合式输尿管软镜治疗和护理,并对其临床效果进行回顾性分析。结果60例患者手术时间为35～90 min,平均（66±15）min,手术过程顺利,结石均完全取出,无残留;术后切口愈合良好,无严重出血、感染等并发症发生,均康复出院。结论输尿管软镜治疗肾结石患者手术切口小,技术含量高,手术室护士熟悉相关器械、熟练掌握手术配合步骤及加强护理配合至关重要。     

管理者过度自信对股权融资成本的影响——基于信息透明度的视角

以2009年和2010年具备股权再融资资格的中国上市公司为研究对象,从信息透明度的角度考察管理者过度自信对股权融资成本的影响。研究发现:管理者过度自信对上市公司的信息透明度和股权融资成本具有负面影响;具体而言,管理者越倾向于过度自信,上市公司的收益平滑度越高,因此收益透明度越低;相比非过度自信管理者所在的企业,过度自信管理者所在企业的股权融资成本更高。     

农村基础设施的经济效应及农民满意度研究——基于山东省44个行政村的实地调查分析

基于对山东省44个行政村的调查分析,本文的主要结论有:环保类基础设施的供给仍十分不足;现有交通基础设施较好地发挥了提高交易效率的作用;进一步开启农村消费市场的目标可以通过降低交通费用来实现;进一步加大对农业生产机械和燃油的价格补贴,可以有效提高农业生产效率;灌溉费用在很大程度上形成农民的负担,过高的通讯费用也抑制了农村通讯业的发展;虽然农民对上级政府的依赖仍然较强,但已具有自愿提供部分基础设施的意愿.

Effects of cross-border capital flows on stock returns of dual-listed firms in mainland China and Hong Kong: Evidence from a natural experiment

This study analyses the effects of the Shanghai–Hong Kong Stock Market Connect policy on the price disparity between A-shares and H-shares of dual-listed companies (DLC). Using a difference-in-difference estimation method, we show that the policy decreases the relative twin cumulative abnormal returns of treated DLC by 3% and narrows the price gaps between A-shares and H-shares. We determine that the rising demand for H-shares, which are newly accessible by mainland investors, drives the price of H-shares up. By contrast, the price of A-shares remains unchanged. Further analysis reveals that cross-border capital flow is the main force of the policy.     

Institutions and geography: Empirical test of spatial growth models for European regions

This article provides an empirical assessment of the growth experiences of European regions, during the period 1991–2004, by taking into account the spatial effects due to both institutions and geography. These effects have been modelled by means of specific controls and by using a non-conventional spatial weight matrix. Results favour a model dealing with substantive spatial externalities. Within this framework, the country-specific institutions are strongly and positively related to the regional productivity's growth rate. In addition, the geo-institutional proximity increases the spatial dependence of the regional output per worker and raises the speed of convergence. By contrast, the pure geographical metrics is underperforming, while underestimating the convergence dynamics.
