科技创新规模扩张和科技创新效率提升是增强国家科技创新能力的两条关键途径。基于现有研究鲜有结合科技创新规模和科技创新效率开展国家科技创新能力评价的现状,采用因子分析法,系统筛选国家科技创新规模影响因素,并结合科技创新效率影响因素,完善国家科技创新能力评价指标体系,通过构建DEA Malmquist指数模型,评价不同时期国家科技创新效率变化指数,以及中国与全球10个国家科技创新能力的时空差异性。研究表明,R&D投入强度、R&D研究人员、专利申请量、科技期刊文章数、高科技产品出口额占制成品出口总额的百分比、科技创新效率是影响国家科技创新能力的关键指标;1991-2014年中国科技创新能力水平呈指数增长态势,有力提升了国家科技实力;全球10个国家科技创新能力水平除日本出现一定波动外,其余九国整体呈小幅递增态势。 相似文献

数字技术可以帮助市场主体重构组织模式,数字经济时代的金融业也因此迎来变革。本文基于2014年至2019年我国县级行政区数据,研究发现,数字金融的发展显著减缓了我国银行业金融机构实体网点的扩张势头,这种效应主要体现在股份制商业银行和城市商业银行上,并主要影响这两类银行的基层机构。同时,我们发现数字金融的发展加快了农村合作金融机构的转型和网点退出,但对国有“六大行”没有显著影响。进一步研究发现,数字金融的影响效果会随着经济发展程度提高和地区金融可得性增加而增强,但随着在位银行的市场势力提升而下降。本文为理解数字经济时代银行业的变迁提供了一定参考。 相似文献

Summary. I show that aggregate-taking behavior is often evolutionarily stable for finite population in symmetric games in which payoff
depends only on own strategy and an aggregate. I provide economic examples exhibiting this phenomenon.

We offer a game-theoretic proof of Hamiltons rule for the spread of altruism. For a simple case of siblings, we show that the rule can be derived as the outcome of a one-shot prisoners dilemma game between siblings.JEL Classification:

This paper is an exercise in the history of thought, which compares Austrian and neoclassical theories of the emergence of
private property rights, and examines, in part, the extent to which Austrians can be said to offer a commonly-agreed upon
explanation that parallels Carl Menger's exemplary story of the emergence of money. We address the sources of disagreement
(and apparent conflict) among emergence theorists in both schools. We try to show that some of the disagreement hinges on
an unclear meaning of the term “emergence,” which is resolvable, while other sources of disagreement are fundamental at the
methodological level.

Recent studies in experimental economics have shown that many people have other-regarding preferences, potentially including
preferences for altruism, reciprocity, and fairness. It is useful to investigate why people possess such preferences and what
functional purpose they might serve outside the laboratory, because evolutionary and social learning perspectives both predict
that cooperative sentiments should only exist if they bring benefits that outweigh the costs of other-regarding behavior.
Theories of costly signaling suggest that altruistic acts may function (with or without intention) as signals of unobservable
qualities such as resources or cooperative intent, and altruists may benefit (possibly unintentionally) from the advertisement
of such qualities. After reviewing the theories that could potentially account for the evolution of altruism (Chapter 1),
I test some predictions about cooperation derived from costly signaling theory. In Chapter 2, I show that participants in
experimental public goods games were more cooperative when they had cues that they could benefit from having a good reputation,
and that there was apparently some competition to be the most generous group member. Furthermore, in subsequent trust games,
people tended to trust high public goods contributors more than low contributors. Chapter 3 failed to find evidence that granting
high status to people makes them more likely to contribute to public goods or punish free-riders, but there was suggestive
evidence that physical proximity to the experimenter affected contributions and punishment. In Chapter 4, I found that people
tended to trust others who were willing to incur costs to punish those who free-ride on group cooperation provided that such
punishment was justified, and men were more punitive than women. In Chapter 5, I show that women find altruistic men more
desirable than neutral men for long-term relationships. Together, these results suggest that humans do treat altruism as a
signal of willingness to be cooperative. These findings are discussed with respect to the adaptive design of cooperative sentiments
as well as the current debate over group selection.

We study a dynamic duopoly model with network externalities. The value of the product depends on the current and past network size. We compare the market outcome to a planner. With equal quality products, the market outcome may result in too little standardization (i.e. too many products active in the long run) but never too much. The potential inefficiency is non-monotonic in the strength of the network effect, being most likely for intermediate levels. When products differ in quality, an inferior product may dominate even when the planner would choose otherwise, but only if the discount factor is sufficiently large 相似文献

参与、不确定性与投资秩序的生成和演化——解读投资者动机和预期的另一个视角 总被引:6,自引:0,他引:6
“中国投资者动机和预期调查数据分析”课题组 《经济研究》2002,(2)
不同于现有主流理论把投资者的动机和预期理解为投资者实现其效用最大化的计算过程 ,本文认为投资者的动机和预期表明投资者对于投资决策的一种参与 ,并在此基础上提出一个解释框架。这一解释框架把投资者动机和预期所包含的对于投资决策的参与态度及感受定义为参与指数 ,不同的参与指数形成不同的投资者群体 ,而不同投资者群体的互动 ,决定着对投资决策最终发生实际作用的投资秩序的生成与演化 ,不确定性正是刻划了投资秩序生成与演变的主观性和非设计性。 相似文献

中央银行再贷款是中国人民银行投放基础货币的重要渠道,是我国特有的一种货币政策工具。基于对新形势下中央银行再贷款制度变迁的分析,现行再贷款政策存在泛化、准财政化、反稳定性、衍生道德风险等问题,必须从制度上规范再贷款的运用,并适时建立金融稳定机制。 相似文献

郭立田 《河北经贸大学学报》2000,21(5):68-73
实施农业科技“跨越”发展方略 ,尽快缩小与发达国家农业科技贡献率的差距 ,是提升我国农业和农村经济素质与效益的必由之路。“跨越”发展为赶超提供了机会与可能 ,只有具备了“跨越”产生的必要和充分条件时 ,这种机会与可能才会成为现实。我国已经具备这些条件 ,问题的关键是如何正确把握跨越式发展的战略思路及运行方案设计 ,以及如何进一步合理确定农业科技发展的优先领域和一步到位直接进入当代最先进农业技术行列的开发推广项目和范围。 相似文献
