政府补贴对企业真实创新绩效的影响——基于中国A股上市公司数据的实证分析

在分析政府补贴政策的特征及其影响企业真实创新绩效的理论机制的基础上,运用A股上市公司数据,检验了政府补贴对企业真实创新绩效的直接和传导效应。研究发现：政府补贴对企业真实创新绩效具有激励效应,且国有企业较非国有企业的创新效应更强;研发资本要素市场扭曲能够强化政府补贴激励企业真实创新绩效的调节作用,并与产权性质联合调节政府创新补贴效果;创新投入与融资约束在政府补贴对企业真实创新绩效的影响中起部分中介效应;政府补贴对企业创新持续性具有负向抑制效应,政府补贴效果受到研发资本要素市场扭曲和产权性质明显的负向调节作用,且创新投入与融资约束在政府补贴对企业持续性创新的影响中起部分中介效应。     

Assessing the market values of soccer players – a robust analysis of data from German 1. and 2. Bundesliga

The paper examines to what extent a player's market value depends on his skills. Therefore, a data set covering 28 performance measures and the market values of about 493 players from 1. and 2. German Bundesliga is analysed. Applying robust analysis techniques, we are able to robustly estimate market values of soccer players. The results show (1) that there are significantly underrated and overrated players and (2) that a player's affiliation to a certain team may contribute to his market value. We conclude that a club's reputation affects the market values of its players and that star players are in tendency overrated.     

A Factor-Adjusted Multiple Testing Procedure With Application to Mutual Fund Selection

In this article, we propose a factor-adjusted multiple testing (FAT) procedure based on factor-adjusted p-values in a linear factor model involving some observable and unobservable factors, for the purpose of selecting skilled funds in empirical finance. The factor-adjusted p-values were obtained after extracting the latent common factors by the principal component method. Under some mild conditions, the false discovery proportion can be consistently estimated even if the idiosyncratic errors are allowed to be weakly correlated across units. Furthermore, by appropriately setting a sequence of threshold values approaching zero, the proposed FAT procedure enjoys model selection consistency. Extensive simulation studies and a real data analysis for selecting skilled funds in the U.S. financial market are presented to illustrate the practical utility of the proposed method. Supplementary materials for this article are available online.     

Participation in Everyday Life Before and After a Housing Adaptation

Housing adaptation aims to enable clients to live independently in their own homes. Studies focusing on participation in everyday life following a housing adaptation are lacking and needed. This study aimed to explore housing adaptation clients' experiences of participation in everyday life before and after a housing adaptation, through the lens of a housing adaptation, using a qualitative follow-up design, with 11 participants. It was found that when the housing adaptation met the participants' needs, performance of activities improved and the housing adaptation opened doors to engagement and participation in everyday life. Thus, focus on performance and engagement in everyday life at the onset of the housing adaptation process, combined with regular follow-ups, may enhance participation.     

我国地方政府创新行为的制度分析

政府创新对于推动政府职能转变、维系政府的政治合法性具有非常重要的意义.地方政府的创新行为由于其自身的特点需要单独进行分析,其创新的原因在于激励和压力双重外力下的制度变迁,由于交易成本较低的自身特点使其具有创新的优势.而由于路径依赖因素的影响,创新过程中存在着诸多障碍.创新的模式可区分为诱致性变迁和强制性变迁两种方式,创新过程中由于经济人的特点容易出现异化的效应,而效果则应该结合政治、经济及社会三方面的因素综合予以考证.     

地震灾后重建绩效测量——以汶川、玉树、芦山地震为例

灾后重建是保障地震灾区群众重归正常生产生活的重要工作,那么如何测量灾后重建绩效,哪些因素会影响灾后重建绩效?文章回顾了灾后重建绩效相关研究文献,在此基础上认为效果和效率是灾后重建绩效的两大方面,以"消除灾害影响并恢复到灾前水平所用的时间"作为衡量灾后重建绩效的标准,能够反映灾后重建的效果和效率,具有可行性。以此为基础建立了灾后重建绩效的分析框架和测量方法,并选择汶川地震、玉树地震和芦山地震作为案例,对三次地震灾区的重建绩效进行了对比分析并简要分析了绩效差异原因。结果表明,三次地震灾后重建基本如期完成了灾后重建目标任务,但因存在灾害程度不同、对口支援质量不同等原因,三次地震灾后重建绩效存在一定差异。     

大学生自我效能感与学业成绩关系的研究

学生的自我效能感是个体在特定情境中对自己的某种行为能力的自信程度,是个体对成功实施并达成特定目标所需行为能力的预期、感知和信心,是介于动机和行为之间的动力因素.自我效能感已成为现代教育心理学研究的热点之一.文章对85名在校大学生自我效能与学业成绩之间的关系进行研究.结果表明,(1)不同学业成绩的学生的自我效能感有显著性差异.优秀组的学生自我效能感明显高于较差组.(2)不同性别、不同专业的学生自我效能感的差异并不显著.
