企业隐性知识管理研究述评

知识经济时代呼唤有效的知识管理,隐性知识作为企业知识的主体和企业创新的原动力,正扮演着越来越重要的角色。本文从隐性知识的内涵与分类、特性与测评、转化与共享等方面对近几年国内外企业隐性知识管理的研究成果进行综述,并分析了目前企业隐性知识管理研究中存在的问题。     

金融中介部门发展与经济增长——基于转型国家的实证检验

通过利用25个转型国家1993-2003年的面板数据,对转型国家金融中介部门发展与经济增长的关系进行检验后发现:存贷款利差与实际GDP增长率互为因果关系;对私人部门信贷的相对增加不仅没有加速经济增长,相反在有些国家还阻碍了经济的长期增长。广义货币量的相对增加对转型国家的经济增长没有促进作用,甚至在CEE和波罗的海国家,M2占GDP的比重与实际GDP增长率之间存在显著负相关。实证结果表明,在软约束盛行的转型国家,提高金融中介部门的效率比其增加其对私人部门的信贷更有利于加速经济增长。     

价格洼地、非市场化供给与收入分配效应——基于长沙楼市的研究

近年来全国房价快速上涨,各地房价出现你追我赶现象。但过去几年,长沙房地产市场却较为平稳,房价水平和上涨幅度与其他同等城市相比,均处于低位,呈现出明显的价格洼地特征。价格洼地的形成与长沙大量土地及住房的非市场化供给有很大关系,并在不同市场主体间产生了财富转移及收入分配效应。     

我国大学科技园发展现状与对策建议

随着知识经济的飞速发展,大学科技园受到越来越多的关注,成为许多国家新的经济增长点,然而在我国由于大学所有制和市场竞争体制的影响,大学科技园在实际建设中遇到许多新问题。本文通过对国内外大学科技园运营状况进行对比,指出了我国在发展大学科技园过程中所遇到的问题和产生的原因,并提出了相应的解决建议。     

人民币汇率形成机制改革的多层面考察

人民币汇率形成机制改革的经济效应可以从宏观、微观和金融市场三个层面进行考察。从宏观层面看,汇率改革能够提高我国货币政策的独立性,但是对减少贸易失衡和调整国际收支的作用并不明显,反而由于持续的升值预期导致大规模资本流入,影响经济金融稳定。从微观层面看.人民币升值对纺织业等行业产生了比较明显的冲击,非贸易品部门则受益于人民币升值,FDI 投资区位的选择也发生了变化,这些都有利于我国转变过度外向型的经济结构。从市场层面看,更大的汇率弹性使企业和金融机构面临的外汇风险上升,但同时也有利于促进外汇市场发展和推动资本账户开放。     

金黄色葡萄球菌蛋白A在大肠杆菌中的自诱导表达以及单克隆抗体的制备

利用大肠杆菌表达金黄色葡萄球菌蛋白A,根据大肠杆菌密码子偏好性对金黄色葡萄球菌蛋白(SPA)基因进行密码子优化。SPA基因插入p ET28a表达载体中,利用自诱导培养基诱导SPA表达,表达量达8.2 mg/L。通过Ni亲和层析纯化SPA蛋白,纯度达到95%。纯化的SPA蛋白免疫小鼠制备单克隆抗体,间接ELISA法检测抗体效价,抗体效价可达1∶40000,采用Protein G亲和层析纯化SPA单抗,纯度达98%。纯化后的SPA单抗检测与食品中常见的致病菌无交叉反应。结果显示,SPA单抗特异性良好,与其他致病菌无交叉反应。     

The nexus between sustainable practices in hotels and future Gen Y hospitality students’ career path decisions

This study explored tertiary hospitality students’ attitudes and overall perceptions about green and sustainable practices; and how these may impact their future career paths in the hotel industry. A thematic analysis with data from 12 semi-structured interviews with students in a hotel management school in Australia was used to identify patterns and interpretive themes. Results revealed positive attitudes among Generation Y hospitality students towards working in a green and sustainable hotel environment. Implications highlight the need for sustainability education in the curriculum of tertiary education providers and strong emphasis on sustainability practices in employee training programs. The results also suggest possible impacts of sustainability practices in recruiting and hiring in the hospitality industry and how this may affect future hospitality employees and leaders.     

Multiperiod Optimal Investment-Consumption Strategies with Mortality Risk and Environment Uncertainty

Abstract

In this article we investigate three related investment-consumption problems for a risk-averse investor: (1) an investment-only problem that involves utility from only terminal wealth, (2) an investment-consumption problem that involves utility from only consumption, and (3) an extended investment-consumption problem that involves utility from both consumption and terminal wealth. Although these problems have been studied quite extensively in continuous-time frameworks, we focus on discrete time. Our contributions are (1) to model these investmentconsumption problems using a discrete model that incorporates the environment risk and mortality risk, in addition to the market risk that is typically considered, and (2) to derive explicit expressions of the optimal investment-consumption strategies to these modeled problems. Furthermore, economic implications of our results are presented. It is reassuring that many of our findings are consistent with the well-known results from the continuous-time models, even though our models have the additional features of modeling the environment uncertainty and the uncertain exit time.     

Strong Growth and Inflation Today

Inflation pressures still bubbling, and there is still risk of a rate hike or two
Industrial production and fixed asset investment growth slowed, but momentum stillseems strong
Policy tightening, especially in terms of real estate, will drag on growth momentum from Q3
