产融结合、高管团队特征与创新效率

选择2010—2018年投资非上市金融企业的中国上市公司数据,通过构建SFA模型实证分析了实体企业产融结合与创新效率的关系,并重点考察了高管团队特征的调节效应。结果发现:实体企业产融结合可显著提升营收创新效率,但会损害其研发创新效率;企业高管团队越高学历化、年轻化、男性化,越倾向投资金融企业,实践产融结合;在产融结合与创新效率的关系中,高管团队特征存在显著的不同程度的调节效应,不同高管团队特征的企业,产融结合与创新效率关系呈现不同的规律。     

新闻与民俗： 地面频道新闻节目的本土化——以《法治现场》为例

《法治现场》对日常纠纷“主持公道”的节目形式,具有独特的民俗文化意味,完全是一种民族的叙事方式。但如果不能自觉地避免祥林嫂式的尴尬情境,就违背了栏目的初衷。辨析得失,可借此探究一条电视新闻本土化的有效途径。     

试论并列式复音词语素结合的深层原因——以核心义为研究视角

语素结合成词的原因以及与之相关的词义生成是复音词研究的重要内容。核心义处于词义结构的深层,是贯穿和统摄词义的一种抽象意义。对于并列式复音词两个语素的相互选择和结合,在某些情况下可以从语素核心义的相互关系中寻求内在依据和深层基础：对语素义相同或相近的并列式复音词来说,语素结合的深层原因可以归结于核心义的共性;对语素义相关的并列式复音词来说,处于语义深层的核心义可以决定表层语素意义之间的关联;对语素义相反的并列式复音词来说,核心义分析有助于理解语素的反义关系以及词义的发展演变。因此,核心义是考察并列式复音词语素结合的重要视角。     

国防科技工业科技安全能力评价

为研究国防科技工业科技安全能力构成并对主要工业领域科技安全能力进行评价,从运行能力、促进能力、保障能力三个维度构建了评价指标体系。为适应评价对象主观性、小样本的特性,运用改进的组合赋权法计算评价指标体系的权重;运用Topsis法对国防科技工业六大工业领域的安全能力进行了比较研究。结果表明:促进能力、保障能力是国防科技工业科技安全能力的核心,运行能力是基础;工业领域发展水平越高,对应科技安全能力越强;促进能力和保障能力分别为国防科技工业科技安全能力最强和最薄弱的方面。     

西藏分裂割据时期诸政教合一体的形成

西藏分裂割据时期,萨迦、帕竹、蔡巴、止贡、夏鲁和雅桑六个政教合一体逐步形成。它们的形成各具特色,但都是教派势力与世俗地方势力的结合体。是西藏政教合一制的雏形

试论中学语文中的虚词教学

汉语缺乏形态变化,虚词乃是表述语法意义与语法关系的重要手段。虚词在汉语中的重要作用是大家公认的。然而,中学语文虚词教学,特别是现代汉语虚词教学,尚未引起足够的重视,在中学语文虚词教学时应注意以下几个问题：（1）利用语境,讲析虚词的意义和作用;（2）通过比较,辨析虚词的意义与用法;（3）点链结合,引导学生在知识系统中掌握虚词;（4）知用结合,引导学生在语文应用中掌握虚词。     

基于一致性组合评价的区域技术创新能力评价与比较分析

利用我们建立的区域技术创新能力评价指标体系和基于一致性的组合评价方法对2005-2007年中国大陆31个省市区域技术创新能力进行总体评价和分项评价,使得评价结果更加科学和客观。对总体和分项评价排序结果进行分类和比较分析,并对评价指标值进行差异分析,找出各区域技术创新能力差异的原因。     

Subjective Probability Weighting and the Discovered Preference Hypothesis

Numerous studies have convincingly shown that prospect theory can better describe risky choice behavior than the classical expected utility model because it makes the plausible assumption that risk aversion is driven not only by the degree of sensitivity toward outcomes, but also by the degree of sensitivity toward probabilities. This article presents the results of an experiment aimed at testing whether agents become more sensitive toward probabilities over time when they repeatedly face similar decisions, receive feedback on the consequences of their decisions, and are given ample incentives to reflect on their decisions, as predicted by Plott’s Discovered Preference Hypothesis (DPH). The results of a laboratory experiment with N = 62 participants support this hypothesis. The elicited subjective probability weighting function converges significantly toward linearity when respondents are asked to make repeated choices and are given direct feedback after each choice. Such convergence to linearity is absent in an experimental treatment where respondents are asked to make repeated choices but do not experience the resolution of risk directly after each choice, as predicted by the DPH. I thank Peter P. Wakker for useful comments and suggestions.     

Probability weighting and the ‘level’ and ‘spacing’ of outcomes: An experimental study over losses

The main goal of the experimental study described in this paper is to investigate the sensitivity of probability weighting to the payoff structure of the gambling situation—namely the level of consequences at stake and the spacing between them—in the loss domain. For that purpose, three kinds of gambles are introduced: two kinds of homogeneous gambles (involving either small or large losses), and heterogeneous gambles involving both large and small losses. The findings suggest that at least for moderate/high probability of loss do both ‘level’ and ‘spacing’ effects reach significance, with the impact of ‘spacing’ being both opposite to and stronger than the impact of ‘level’. As compared to small-loss gambles, large-loss gambles appear to enhance probabilistic optimism, while heterogeneous gambles tend to increase pessimism.
