CAPM模型在上海股票市场的实证研究
The Empirical Research of the Capital Asset Pricing Model in Shanghai Security Market
 [PDF]


World Economic Research (WER) , 2014, DOI: 10.12677/WER.2014.32003
Abstract:

为研究CAPM模型在中国股票市场的适用性,本文以上海股市为研究对象,首先选取2002年12月31日以前上市且处于正常交易的640只沪市A股作为样本,通过同花顺炒股软件筛选出2003年1月至2012年12月历时十年的经除权、除息处理后的月收益率数据。然后运用时间序列检验和横截面检验相结合的方法对沪市A股股票月收益率与β系数的关系进行检验,并分析其风险构成。最后,时间序列检验和横截面检验得出CAPM模型在上海股市非有效的结论。
 In order to study the application of the Capital Asset Pricing Model in China stock market, the thesis regards the Shanghai Stock Market as the research object. Firstly, a list of A shares was selected, that means 640 stocks in Shanghai Stock Market as the sample was listed before December 31st in 2002 and in the situation of normal trading. Then, the data of monthly yield were filtered out by ex-dividend processing, which dates from January 1st in 2003 to December 31st in 2012. Afterwards, by using time series and cross-sectional test methods, the relationship between monthly return and beta of A shares in Shanghai Stock Market was tested. Furthermore, risk structure was analyzed. Finally, both the time series inspection and the cross-sectional inspection draw the conclusion that the CAPM is not effective in Shanghai Stock Market.

相貌吸引力对收入影响的文献综述
Literature Review about Appearance Attractiveness’s Effects on Income
 [PDF]


Business and Globalization (BGlo) , 2014, DOI: 10.12677/BGlo.2014.23007
Abstract:
近几年,随着美貌经济学逐渐步入大众的视野,越来越多的国内外学者专注于研究劳动力市场上相貌吸引力对收入的影响。对于美貌,经济学家将其视为一种稀缺性生产资源,并认为劳动力市场上普遍存在着“美貌溢价”和“丑陋罚款”现象;心理学家则把“相貌歧视”解释为一种人类普遍存在地潜意识的心理自我保护反应。为了深入探究隐性的相貌歧视问题,本文对国内外相关文献进行系统性梳理,从不同视角阐述美貌对收入的影响,并分析劳动力市场存在相貌歧视的原因,最后提出应对相貌歧视的有效建议。
Over the years, with the “Economics of Beauty” gradually coming into the public’s vision, more and more scholars both in China and abroad, have started to focus on the research about appearance attractiveness’s effects on income. As for beauty, economists regard it as a kind of scarce productive resources and hold the view that there does exist “Beauty Premium” and “Ugliness Penalty” in the labor market. Instead, psychologists think of “Appearance Discrimination” as a common human subconsciously self-protection phenomenon. In order to have a deep understanding of the hidden “Appearance Discrimination”, we systematically comb the related literature both at home and abroad, expound the beauty’s effects on income through a different lens and explore the reasons why labor market exists “Appearance Discrimination”. Finally, we put forward some effective suggestions for dealing with the problem of “Appearance Discrimination”.

Emergence and Transfer of Wealth (ETW) , 2015, DOI: 10.12677/ETW.2015.52003
Abstract:
改革开放以来,伴随着“效率优先、兼顾公平”的经济发展战略,我国经济高速腾飞。与此同时,腐败日益滋生蔓延,贫富差距进一步扩大。为了探究经济增长、腐败与收入不平等三者之间究竟有何关系,本文拟从梳理经济增长与收入不平等、经济增长与腐败、腐败与收入不平等两两因素间关系着手。
Since the beginning of the opening up policy, along with the economic development strategy of “Ef-ficiency Priority, Fairness taken into consideration”, China’s economy has been booming. While at the same time, the problem of corruption has been growing and spreading, the gap between the rich and the poor has been widening. In order to explore the relationship between economic growth, corruption and income inequality, the paper intends to study the relationships between the every two factors, in other words, the relationship between economic growth and income inequality, the relationship between economic growth and corruption, the relationship between corruption and income inequality.

E-Commerce Letters (ECL) , 2015, DOI: 10.12677/ECL.2015.43009
Abstract: 2013年可谓中国互联网金融元年。伴随着以“余额宝”为代表的互联网金融理财产品的诞生,互联网金融逐渐步入大众视野,并引起了学者的广泛关注。在此背景下,本文拟从互联网金融的内涵、背后蕴藏的经济学理论、对传统银行业的影响、传统银行业应对互联网金融冲击、互联网金融面临的风险以及法律规制等视角,对互联网金融的相关文献进行系统性梳理。
2013 can be described as the first year of China’s Internet of Finance (IOF). With the birth of wealth-management products of IOF, represented by the balance of treasure, IOF has gradually entered the public’s view and has aroused wide attention of scholars. Given this backdrop, the pa-per intends to systematically comb the relevant literature from a variety of perspectives, including the connotation of IOF, economic theory behind IOF, the impact of IOF on traditional banking in-dustry, how traditional banking industry deals with the impact of IOF, risks and legal regulation IOF facing, and so on.

Abstract: ?许多外源及内源性因素均可导致dna损伤,从而对遗传信息的有效传递甚至生物体的生存造成极大的威胁。真核细胞依靠长期进化出的dna损伤应激反应(ddr)系统来对抗dna损伤。dna双链断裂(dsb)是最为严重的损伤形式之一,dsb修复失败会导致细胞死亡、遗传疾病以及肿瘤发生等严重后果。真核细胞中主要存在2种dsb修复方式:同源重组(hr)和非同源末端连接(nhej)。本文介绍了hr和nhej通路的执行过程和参与成员,并对当前hr和nhej修复通路选择和调节机制的最新研究进展进行综述。

草地沙化过程地上植被与土壤种子库变化特征


生态学报 , 2003,
Abstract: 研究了草地沙漠化过程地上植被与土壤种子库的变化特征。获如下结论:(1)草地沙漠化过程地上植被与土壤种子库物种多样性的衰减模式不同,土壤种子库植物种数从潜在沙漠化阶段(固定沙地)到中度沙漠化阶段(半流动沙地)变化很小,而从中度沙漠化到严重沙漠化阶段(流动沙地)衰减速度明显加快;地上植被种数随着沙漠化程度增加而下降,其中从中度沙漠化到严重沙漠化发展阶段衰减幅度最大。(2)地上植被与土壤种子库密度随着沙漠化程度增加而下降,但下降速率因沙漠化发展阶段不同而异,从固定到半固定沙地是地上植被与土壤种子库密度下降最快的时期。(3)地上植被与土壤种子库共有种数随着沙漠化程度的增加而减少,从而导致了地上与土壤种子库群落组成的相异性增大。(4)4种退化沙地土壤种子库组成的相似性要高于地上植被,表明在沙漠化过程中土壤种子库群落组成的稳定性要高于地上植被。(5)地上植被密度与土壤种子库密度存在显著相关性,其关系可用二次曲线来描述。

Abstract: 运输车辆超限超载对公路造成了极大的破坏,也引发了大量的交通事故。为了有效遏制车辆超限超载,保障交通运输安全顺畅,一种新的收费模式计重收费应运而生。以京津冀高速公路联网收费区域计重收费数据为样本,量化分析实施计重收费前后超限超载车辆比例的变化情况;实施计重收费四年来不同轴型的货运车辆超限超载运输的变化趋势以及运输车辆车型结构分布的变化情况。分析结果表明超限超载车辆明显下降,从实施前的22.21%下降至2011年底的5.68%;多轴(六轴及以上)货运车辆的比例逐年提高,由实施初期的27.55%上升到2011年底的42.11%。计重收费政策对抑制超限超载运输、促进运输业车型结构优化调整发挥了重要的作用。
职工薪酬核算与个人所得税的关联性思考

财会月刊 , 2008,
Abstract:   为了加强对个人所得税的监管,本文阐述了职工薪酬与计算、代扣代缴个人所得税的关系,提出了建立个人所得额计税账户监管体系,建立企业与税务部门双链动态管理个人所得税的监管模式。  【关键词】职工薪酬个人所得税双链动态管理  财政部颁发的《企业会计准则第9号——职工薪酬》(以下简称《职工薪酬准则》)是企业职工薪酬核算与管理的理论依据,2008年3月1日起施行的《个人所得税法》和《个人所得税法实施条例》(以下简称《条例》)是企业代扣代缴或个人申报缴纳个人所得税的法律准绳,它们从不同层面诠释了个人所得税的重点与内容。为了加强对个人所得税的监管,本文分析了职工薪酬核算与个人所得税的关联性问题,提出了以职工薪酬核算为基础,建立个人所得额计税账户监控体系,建立全国各税务部门计算机网络信息系统,从而形成税务部门与企业双链动态管理个人所得税的监管模式。  一、职工薪酬与个人所得税关联性分析  1.职工工资、奖金、津贴和补贴。《职工薪酬准则》规定的工资是由按照国家统计局规定构成工资总额的计时工资、计件工资、奖金、津贴、补贴等确定,与《个人所得税法》所指的工资、薪金所得的口径基本相同。《个人所得税法》规定,个人因任职或者受雇而取得的工资、薪金、奖金、年终加薪、劳动分红、津贴、补贴以及与任职或者受雇有关的其他所得应缴纳个人所得税。《条例》第二十五条规定,单位为个人缴付和个人自己缴付的基本养老保险费、基本医疗保险费、失业保险费、住房公积金,从纳税义务人的应纳税所得额中扣除。企业代扣职工个人所得税=∑[(个人月工资收入-2000)×各适用税率-速算扣除数]。
