The Effect of Enterprise Property and Inefficient Investment on Company Performance——an Empirical Study on the Data of A Share Listed Companies
对于公司的可持续发展和未来现金流的增长,投资决策的作用举足轻重,公司的投资效率决定了其发展前景和整体价值。鉴于中国的特殊国情,企业性质是分析上市公司非效率投资时的重要考察因素。本文探究了上市公司的非效率投资水平与公司绩效之间的相关性,并区分国有企业和民营企业两种不同的企业性质,进而考察不同性质企业的投资行为对提升公司绩效的影响。 本文选取了2007—2015年我国非金融类A股上市公司的非平衡面板数据作为研究样本,共9368个观测值(包含1732个滞后数据)。实证部分主要运用了两个多元线性回归模型,先估计企业的非效率投资水平,再探究非效率投资与公司绩效的关系。其中的模型2加入了两个子模型,以区...For the sustainable development of the company and the growth of future cash flows, investment decision plays an important role.

Talent Selection Mechanism for X Corporation Based on Competency Model
胜任力模型关注一个人的个性、动机、态度、价值观等内在素质,从人性和情感的角度来看待影响一个人成功的因素。但是,当前素质模型的应用还处于摸索阶段。也正因此,本文作者对素质模型研究充满浓厚兴趣,以X公司胜任力模型的建立、运用为范例,来研究有关素质模型的建立方法,研究素质模型在人力资源管理活动中应用的问题。 然而,如何形成企业的胜任力模型,并将胜任力模型应用到人才选拔中呢?本文作者在借鉴成熟成果及经验的基础上,避开常规的、但对企业人力资源工作者而言难以实施的胜任素质模型的建立程序,结合公司的实际情况,提出基于企业素质模型的人才选拔体系的设计思路,并针对胜任力模型在X公司人才选拔的实施效果进行总结不...Competency-based model focuses on an individual’s intrinsic quality, such as one’s personality, motivations, attitudes, and values. Under this model, human nature and emotion are considered as the factors that will affect an individual’s success. However, competency-based model is not a mature approach yet. It is because this approach is still in its initial stage that my interest in this subject ...学位:工商管理硕士院系专业:管理学院高级经理教育中心(EMBA项目)_高级管理人员工商管理硕士(EMBA)学号:X200815621

An Empirical Study on the Closing Price Mechanism and its Impact on the Quality of Chinese Stock Market
市场微观结构理论认为,交易机制在决定价格形成的过程中会对市场质量产生影响。收盘机制作为交易机制的一部分在收盘阶段对市场质量产生重要的影响。2006年7月1日,深圳证券交易所将收盘机制改为开放式集合竞价,至此我国沪深两市分别采用两种不同的收盘机制决定收盘价格。通过研究这两种不同的收盘机制对市场质量的影响,可以改进我国证券市场的收盘机制并且完善我国证券市场微观结构,所以这对于市场监管者、设计交易机制的证券交易所以及投资者都有着重要的意义。 本文首先对交易机制进行概述,介绍了交易机制的基本内容以及我国证券市场的交易机制,并阐述了市场微观结构与交易机制的关系。接着从市场质量与交易机制的关系入手,阐述...Market microstructure theory indicates that the trading mechanism in determining the price formation process would have an impact on market quality.

Photosynthetic capacity of three common species of macroalgae and the application in coral aquarium
利用水下饱和脉冲调制叶绿素荧光仪(dIVIng-PAM)测定了珊瑚养殖水处理中3种常见大型海藻石莼(ulVA lACTuCA)、条浒苔(EnTErOMOrPHA ClATHrATA)和羽状蕨藻(CAulErPA MEXICAnA)光能转化效率(fV/fM),快速光曲线(rlC)相关参数和非光化学淬灭(nPQ)。结果表明:石莼和条浒苔的fV/fM分别为0.808±0.004和0.816±0.009,显著高于羽状蕨藻。最大相对电子传递速率rETrMAX(17.52±2.92和19.59±4.43μMOl E·M-2·S-1)、半饱和光强Ik(53.41±8.18和59.71±13.52μMOl PHOTOnS·M-2·S-1)也明显高于羽状蕨藻(rETrMAX和Ik分别为13.72±5.41μMOl E·M-2·S-1和32.67±14.06μMOl PHOTOnS·M-2·S-1),表明石莼和条浒苔有着比羽状蕨藻更高的光合能力和对强光的耐受能力,光保护能力更强;羽状蕨藻较高的rlC初始斜率α表明其在弱光下拥有更强的光捕获能力,弱光下光合效率更高;随光照的增强(0~373μMOl PHOTOnS·M-2·S-1),羽状蕨藻nPQ的增幅有限(0~0.2),最大值仅为条浒苔和石莼的38.1%和62.5%,表明这种藻类更容易受到强光的抑制。因此,在珊瑚养殖的水处理中,可以根据不同的光照选择适宜的藻种或藻种组合并根据光梯度进行布局,反之也可以根据藻种来选择合适的光源,以达到最佳的处理效率。This study investigated the difference of photosynthetic capacity in three macroalgae species( Ulva lactuca,Enteromorpha clathrata,and Caulerpa mexicana) commonly used for nutrient removal in coral aquariums.The photochemical efficiency( Fv/Fm),parameters relevant to rapid light curve( RLC) and non-photochemical quenching( NPQ) in the macroalgae were measured by underwater saturation pulse modulated chlorophyll fluorometer( Diving-PAM).The results showed that Fv/Fmwas 0.808 ± 0.004 for U.lactuca and 0.816 ± 0.009 for E.clathrata,which were higher than that for C.mexicana.Higher maximum relative electron transfer rates( rETRmax)( 17.52 ±2.92 and 19.59 ±4.43 μmol e·m- 2·s- 1) and half-starved value of light intensities( Ik)( 53.41 ±8.18 and 59.71 ±13.52 μmol photons·m- 2·s- 1) were observed in U.lactuca and E.clathrata than that in C.mexicana( 13.72 ± 5.41 μmol e·m- 2·s- 1for rETRmaxand 32.67 ± 14.06 μmol photons·m- 2·s- 1for Ik),indicating that U.lactuca and E.clathrata have stronger photosynthetic capacities,photo-protection capacities and tolerance to higher intense light than C.mexicana.A significantly lower RLC initial slope α in C.mexicana implied that this algal species has a higher photosynthetic capacity under weak light condition.With increasing the light intensity( 0- 373 μmol photons·m- 2·s- 1),however,C.mexicana had a limited increase of NPQ( 0- 0.2),the maximum of which was equivalent to 38.1% of that in U.lactuca and 62.5% of that in E.clathrata.These results indicate that the photosynthesis of E.clathrata may be more easily limited by intense light.Our study suggests that the selection of algal species for nutrient removal in a coral aquarium should be adapted to the light intensity.Single species or the combination of different species of macroalgae can be selected according to the illumination of the coral aquarium in order to maximize the efficiency of nutrient removal.国家海洋局第三海洋研究所基本科研业务项目(海三科2011033); 厦门海洋研究开发院共建项目; 海洋公益性行业科研项目(201105012)资

Impact Factors Analysis on Chinese Urban and Rural Residents-Based on CGSS(2003-2006) Data Analysis
对居民幸福感的研究是最近国际学术界中较为前沿的经济学研究方向。对于幸福感的研究始于社会学领域,一直以来,学术界对幸福感的研究集中在心理学、社会学、医学和人口统计学领域,并与1974年首次正式进入经济学家的研究视野。经过三十余年的发展,学术界已经取得许多突破性的进展,并逐渐形成一门新兴的学科。本文在回顾国内外学术界对个体幸福感研究的理论演进与最新进展基础的上,对幸福感的生成机理进行分析,然后利用2003-2006年的全国综合社会调查数据(CGSS),对我国城乡居民的幸福感水平的决定因素进行了分析。 本文的实证结果表明,总体上,城镇户口的确能够对居民的幸福感水平产生显著的正向影响,但是,控制了...Residents’ SWB (Subjective Well Being) research is a frontier of academic economics research recently.
