金融集聚对经济增长的知识溢出机制研究

从金融地理学的角度出发,运用演化博弈模型分析得出,金融集聚有利于区域内知识溢出效应的发挥,通过集聚网络知识的系统效应、创新效应、技术进步效应和信息升级效应,提升中心区域内的经济发展水平。此外,如果区域间知识水平差距过大,会形成知识锁定的局面,造成区域间知识溢出阻塞效应,拉大区域间主体知识水平差距,从而加剧区域间经济发展的不均衡。因此,营造区域间良好的金融生态环境,对落后区域的企业给予更多的金融支持,拓宽中小和新兴企业的融资渠道,引导性地使金融集聚发挥辐射作用,能够使金融的正向集聚效应提升经济发展水平。     

A joint examination of effects of decision task type and construal level on the attraction effect

The attraction effect refers to a situation in which adding an inferior alternative to a choice set increases the share of the relatively dominating alternative. This research posits that decision task type affect the attraction effect. People usually seek justification for their decisions. In a selection (or rejection) task, they are more likely to emphasize the positive (or negative) features of each option. The addition of an asymmetrically dominated decoy to a binary set of options undoubtedly provides an extra positive feature for the dominant option, and therefore induces a greater attraction effect. Contrarily, in a rejection task condition, the decoy in the trinary set seems to be the worst option and would be eliminated first, and the remaining comparison is identical with the original binary condition. Therefore, the attraction effect may decrease. Besides, the decision task type interacts with the construal level to affect the attraction effect. Specifically, a low construal level, compared with a high construal level, dampens the attraction effect to a greater extent in a rejection task than in a selection task. Results from three experiments support the proposed hypotheses.     

阶层分化与农民层级迁移

“乡—城”迁移假定农民由乡村向城市迁移,这一假定遮蔽了实践中农民迁移方向的多元性,阶层分化是基本影响因素。以武陵山区龙马乡为例,田野调查发现公共品供给贫困,农民普遍要求迁移。然而实践中农民迁移路径受制于农户拥有的初始资本和可持续生计来源,不同阶层农民的迁移路径呈现层级性。农民迁移在目的地上表现为从城镇、中间集镇到中心村的地域层级,各迁移路径性质分别是非农化迁移、过渡性迁移和农村内部迁移,这种农民迁移实践可以归纳为“层级迁移”。层级迁移是农民阶层分化背景下的农民迁移基本规律。     

民营企业人力资本薪酬策略设计及其运用方法研究

基于薪酬是作为激励企业不同类型人力资本价值实现的重要经济杠杆,对不同类型人力资本采取不同的薪酬策略显得尤为重要。鉴于我国民营企业①人力资本薪酬水平相比其他性质企业仍很低,企业人才的激励、留用与争夺都处于劣势。本文从薪酬结构、薪酬水平以及薪酬组合三方面制定民营企业不同类型人力资本薪酬策略设计原则及其具体运用方法,旨在增强民营企业薪酬的外部竞争性、内部一致性以及绩效激励作用,从而提升民营企业人力资本薪酬竞争力。     

企业家精神的内涵与外延探析

从企业家精神的内涵和外延两个角度对企业家精神的定义进行整合,从个体特性、行为特性和与环境相结合的特性整合企业家精神的内涵,同时将企业家精神的外延划分为个人层次、组织层次和社会层次三个层次范围。从而进一步得出企业家精神的研究框架,并在框架的基础上分析当前国内研究的不足。最终,根据对企业家精神的深入分析,预测出企业家精神未来的研究趋势。     

Unit Root Tests in the Presence of Multi-Variance Break and Level Shifts That Have Power Against the Piecewise Stationary Alternative

Structural breaks in the level as well as in the volatility have often been exhibited in economic time series. In this paper, we propose new unit root tests when a time series has multiple shifts in its level and the corresponding volatility. The proposed tests are Lagrangian multiplier type tests based on the residual's marginal likelihood which is free from the nuisance mean parameters. The limiting null distributions of the proposed tests are the χ²distributions, and are affected not by the size and the location of breaks but only by the number of breaks.

We set the structural breaks under both the null and the alternative hypotheses to relieve a possible vagueness in interpreting test results in empirical work. The null hypothesis implies a unit root process with level shifts and the alternative connotes a stationary process with level shifts. The Monte Carlo simulation shows that our tests are locally more powerful than the OLSE-based tests, and that the powers of our tests, in a fixed time span, remain stable regardless the number of breaks. In our application, we employ the data which are analyzed by Perron (1990), and some results differ from those of Perron's (1990).     

论学术抄袭与当前的浮躁学风问题——兼谈如何进一步开展学术批评

学术批评的重心应由当前的以揭露、批判抄袭剽窃的个案为主,转移到以检讨、反思、整治低水平、重复研究和互抬桥子为主要特征的群体浮躁上来;把学术批评的强音由当今的“学术打假”、“反学术腐败”,改换成“提倡学术规范,反对学术浮躁、学术泡沫”;把学术批评的个人见义勇为的“傻瓜的事业”,真正纳入到社会主义精神文明建设的重要议程,各级学术主管部门已到了发挥其应有的作用的时候了。     

加强党的领导，切实做好县级统战工作

县级统战工作是我们党统一战线工作的基础。但目前还存在一些亟待解决的问题,如统战部门工作机制不够合理、县级党委对统战工作的重视不够等。为此,我们应切实加强和改善党的领导,加强县级统战工作的队伍建设,不断促进县级统战工作的发展。     

意识形态层次类型的生成及其变迁

传统理论通常仅从阶级对立关系把意识形态归结为理论体系,忽视了意识形态的多种层次类型。依据意识形态信守主体的不同,可以将其划分为总体意识形态、群体意识形态和个体意识形态。三种层次的意识形态在生成方式、表现形式和演化进程等方面既有密切联系,又有明显区别。在经济社会和思想文化快速发展的新形势下,应当突破把意识形态仅仅归结为理论体系的抽象认识,直面各种层次生动而复杂的意识形态现象,真实而具体地把握不同社会层面意识形态的新变化与新特点。     

法律是低层次的道德吗?——兼论法治文明中的法律和道德

社会生活中一直有所谓“法律是低层次道德”的观点。这种观点不仅逻辑前提虚构,而且在中国还与传统“法刑观”和“德主刑辅”论有着内在的联系,在很大程度上对中国法治建设产生了消极影响。法治文明中的法律是基本的道德。所谓基本道德就是能够也需要转化为法律的道德。基本道德是社会生活有序化和规范化的基础,也是社会生活中最重要的不可忽缺的道德。基本道德的这种性质,决定了基本道德的维护通常不能仅以道德的手段,而且主要以法律的手段,故出现了基本道德向法律的转化。同时,基本道德也是非基本道德得以存在的前提和依据,尊重基本道德是非基本道德的前提。非基本道德不得违背基本道德,更不能破坏基本道德。这是全面贯彻和落实科学发展观,建设社会主义法治国家和全面推进社会主义精神文明的需要。
