高职院校产学研合作模式及其发展对策

高职院校要实现培养目标,满足国家对高素质技能人才培养的需求,汲取社会资源促进高职教育持续健康的发展,必须走产学研合作的道路。针对高职院校产学研合作的现状及存在问题,分析当前推进产学研结合亟需建立运行主体间的深层次合作关系及长效运行机制,提出产学研合作实践中要明确和探索的问题。在当前高等教育实现大众化并飞速发展的形势下,高职高专要生存,要发展,就要正确定位,明确办学目标,培养大量的、符合市场需要的应用型人才,走有特色的产学研结合之路。     

大学英语学习者语用能力的调查

本文采用Jenny Thomas提出的"语用失误"理论为框架,对不同层次大学英语学习者的语用能力进行了问卷调查,数据统计结果显示大学英语学习者的整体语用能力偏低。处于不同学习阶段的三组学习者呈现相似的语用能力,学习者的语用能力不会随着语言能力的提高而提高。     

资质认定实验室如何进行管理评审

为了衡量管理体系是否符合自身实际状况,评价管理体系对自身管理工作是否真正有效,是否能够保证质量方针和目标的实现,实验室最高管理者要组织管理评审工作,确保管理体系持续适用和有效,并进行管理体系的不断改进。     

论高职高专行业英语教育改革

高职高专行业英语的发展不仅反映当前社会对英语人才的多元化需求,也是高职院校英语教学的一个最终发展趋势,并且是体现高职高专办学目标的一个重要构成部分。因此,为了改善当前高职高专英语教学中的诸多问题和顺应社会对于高职学生英语能力的需求,我们有必要对行业英语进行进一步的探究,以制定出较为明确的发展思路。     

Mixed oligopoly, optimal privatization, and foreign penetration

This paper examines the impact of foreign penetration on privatization in a mixed oligopolistic market. In contrast to the simple framework of single domestic market with foreign entry by entry mode of foreign direct investment (FDI) or exports, our result shows that government should increase the degree of privatization along with increasing proportion of domestic ownership of multinational firms. Furthermore, we show that an increase in domestic ownership of multinational firms raises all domestic private firms' profit and social welfare, while it may either increase or decrease public firm's profit. With the aid of numerical example, intensive competition from private firms in general will enhance the degree of privatization gradually; in particular, the degree of privatization is lower in the presence of multinational firms.     

Testing for structural breaks in panel varying coefficient models: with an application to OECD health expenditure

In this article, we propose a model selection approach for testing structural breaks in a semiparametric panel varying coefficient model. Monte Carlo evidence shows that the proposed model selection approach performs well in finite sample settings. Applying the method to an empirical data, we find evidence of structural breaks in Organisation for Economic Co-operation and Development (OECD) health expenditure data by allowing for income elasticity to be state (income)-dependent. The relationship between health expenditure and income is subject to two types of structural changes: smooth changes over income and structural breaks in the time dimension. The findings hold for both foreign exchange rate-converted and Purchasing Power Parity-converted expenditure and GDP.     

Financial leverage and market volatility with diverse beliefs

We study a general equilibrium model of asset trading with financial leverage, where the investors can engage in speculative trading with diverse beliefs about the asset??s fundamental value. We show that an increase in the leverage ratio causes the stock price to rise in the current period through a ??leverage effect??, and will result in more borrowing and more stock purchase that pumps the stock price higher in the subsequent period, known as the ??pyramiding effect??. There can also be a ??depyramiding effect?? when the price falls because lenders issue margin calls and force stock sales, contributing to further stock price plummeting. Price changes from depyramiding effect, however, may not take effect when margin calls are not triggered. We demonstrate that, under certain conditions, decreasing leverage ratios leads to lower stock price volatility, measured by the variation of prices caused by an exogenous shock, when the shock is unanticipated. The influences of dispersion of beliefs and available investment funds on the relation between financial leverage and market volatility are also examined. When the shock is anticipated, we demonstrate that reducing leverage ratios may not lower stock price volatility, which poses an important challenge to future studies on this issue.     

量化宽松货币政策下美国的消费投资与全球流动性泛滥

美联储试图通过量化宽松货币政策的实施刺激国内私人部门消费和投资的增长。研究表明,由于美国经济的问题不是流动性短缺,因此,量化宽松货币政策不仅没有带来美国经济的复苏反而带来全球美元流动性泛滥,强化了全球经济运行的不稳定性和不确定性。作为国际货币的主要发行国,美国应该放弃这种与邻为壑的量化宽松货币政策,以保持全球经济和金融的稳定。     

改善民生是中国城乡统筹改革实践的原动力

民生是中国城乡统筹改革实践的原动力。改革起始期,是民生呼唤下的自发改革与政策调整;改革深入期,是民生推动下的体制转轨与制度创新;改革攻坚期,是民生引导下的统筹发展与新农村建设。30年农村改革历程,致使民生问题的不断解决与改革的渐进式节奏相互吻合,推动着"人本"式的农村改革健康有序地发展。     

基础设施、拥挤性与城市生产率差异——来自中国267个城市市辖区数据的实证研究

针对我国城市空间结构和劳动生产率差异明显的现状,对我国267个地级城市的基础设施情况进行指标评价,并根据评价结果实证分析了基础设施水平、城市拥挤性对城市生产率的影响。研究结果表明,基础设施和就业密度对我国城市生产率的积极作用,同时两者的合力对城市生产率具有较强的驱动作用。
