人口老龄化与人力资本提升在经济增长中的对冲效应研究

人口老龄化和人力资本水平提升是人力资源发展的两大趋势.人口老龄化会减少劳动力的有效供给,进而抑制经济增长;人力资本水平提升则会提高劳动生产效率,进而促进经济增长,并可通过增加劳动力的有效供给来"对冲"人口老龄化对经济增长的抑制效应.采用2000-2017年中国31个省(自治区、直辖市)的面板数据,运用动态系统GMM模型...     

我国"以市场换技术"引资战略的历史透视

“以市场换技术”作为我国引资实践的一项重大战略,是在20世纪80年代初开始逐步形成的,先后经历了一个从试验探索到正式确立、从数量扩张到质量提高的发展历程。“以市场换技术”依次经历了试验探索阶段、数量扩张阶段和调整提高阶段,三个阶段的基本情况、政策法规和阶段特征有其不同之处。     

被误解的“顺应” ——语言顺应论之深度“误读”反思

基于一手文献文本针对顺应论所遭遇的诸多误解进行反思。结果发现,顺应论所遭遇的误解可以归结为如下四个彼此相关的命题:(1)在哲学基础上,顺应论被看作为一种与英美"分相观"相互对立的观点;(2)在根本目的上,顺应论被非理性地过分缩限于理论建构之上;(3)在根本属性上,顺应论被定性为轻视心智研究的社会语用学范式;(4)在方法论上,顺应论被责难以"过于宽泛、失之微观"。最后,文章结合国际语用学界"解放语用学"的呼声就顺应论具体应用应该注意的问题作了探讨。     

Existence and Uniqueness of Solutions to the Bellman Equation in the Unbounded Case

We study the problem of the existence and uniqueness of solutions to the Bellman equation in the presence of unbounded returns. We introduce a new approach based both on consideration of a metric on the space of all continuous functions over the state space, and on the application of some metric fixed point theorems. With appropriate conditions we prove uniqueness of solutions with respect to the whole space of continuous functions. Furthermore, the paper provides new sufficient conditions for the existence of solutions that can be applied to fairly general models. It is also proven that the fixed point coincides with the value function and that it can be approached by successive iterations of the Bellman operator.     

Overeducation of Young Workers in Spain: How Much Does the First Job Matter? Social Indicators Research

This article contributes to recent overeducation literature on the impact of an initial education mismatch on workers’ future careers. Specifically, using the 2009 ad-hoc module of the Spanish Labour Force Survey, we quantify the differences in the probability of overeducation depending on the quality of individuals’ first match. To do this, we apply an extension of the recursive bivariate probit model, which allows potential endogeneity problems to be taken into account, as well as a dissimilar impact of the initial match for workers with different educational attainment. The results indicate that overeducation is a trap, since young workers who were mismatched in their first job are 40.2 percentage points more likely to be overeducated in a later one than those who were not. When decomposing this difference in two parts, one related to the pure effect of the initial mismatch and another one related to workers’ characteristics, we conclude that the pure effect is more important, and it depends on educational attainment.     

Spatial Analysis of the Relationship Between a Life Quality Index,HDI and Poverty in the Province of Buenos Aires and the Autonomous City of Buenos Aires,Argentina

The study of Quality of Life, Poverty and Human Development shares several elements. Nonetheless, while poverty is a measure of “lack” based on a set of basic need variables (unsatisfied basic needs—UBN), human development index (HDI) is derived from the notion of human capabilities. Quality of Life, however, is a measure of achievement. Our goal is to analyze the degree of spatial correspondence between a life quality index (LQI) and the other indices by using bivariate spatial autocorrelation with its global and local values. The comparison of these three indicators at a municipal level in the province of Buenos Aires and in the Autonomous City of Buenos Aires (the Federal Capital of Argentina) reveals a medium spatial correspondence which leaves room for discussion about the scope and limitations of the indicators. HDI and UBN have a similar spatial configuration while the LQI yields a more fragmented distribution associated to the complexity of its variables, dimension and weights.     

试论苏青笔下的母性情结

与众多现当代女作家不同,苏青的“母性情结”来源于她内心的最深切的体验,而这恰是构成其作品的基点。文章试从母性本体的失落、母性情结的回归、现代母性的期待等三个方面剖析苏青笔下的独特的母性情结,具有一定的合理性和超前性。     

会计诚信缺失的机理分析

安然事件暴露了会计体系与公司治理方面的缺陷 ,因为对股东而言 ,他们难以接受在投资风险中还含有“会计作假风险”这个风险因素。通过建立博弈模型可以发现 ,现有企业制度破坏了所有者、企业、会计师事务所三方的利益及风险制衡关系 ,而形成了企业与监管者、事务所与监管者两种利益关系。在前者关系下 ,会计诚信度高且持久 ;在后者关系下 ,会计诚信度不但低 ,而且随着监管有效度的高低而时隐时现。因此 ,如何提高监管体系的有效程度变得非常重要。     

以媒体素养教育促进高校思政信息化的思考

对高校开展媒体素养教育的现状、必要性进行分析,挖掘当前思政教育方面存在的问题,主要包括整体教育水平、教育内容、教育形式等方面,并提出科学有效的措施,力求通过建立媒介素养教育体系、充分利用现有教育资源、发挥校园媒体辅助作用、加强媒介素质理论教育等方式,充分发挥媒介素养教育的重要作用,从而促进高校思政信息化建设提供更大的促进作用。     

应用型本科高校混合式教学模式研究 ——以宿州学院为例

采用定量分析与定性分析相结合的方式,对来自宿州学院的180名学生和20名教师进行调查和访谈,调查宿州学院教学模式现状,结合应用型本科高校的特点和实际情况,进行混合式教学模式流程设计,介绍实施混合式教学模式的方法,包括加强学生的实践锻炼,鼓励教师到企业参观交流实习,学校层面加强支持与管理等。并在宿州学院商学院市场营销专业试运行,运行前后对比,发现实施混合式教学模式以后,学生的学习兴趣提高,教师自身价值得到发展,可见实施混合式教学模式势在必行。
