中国二元结构的演化及特点
The Evolution and Characteristics of China’s Dual Economic Structure  [PDF]
郭锦川, 李琼
Modern Management (MM) , 2011, DOI: 10.12677/mm.2011.13020
Abstract: 我国二元经济结构最早可以追溯到19 世纪中叶。1949 年建国后，由于选择了重工业优先发展的赶超型发展战略，二元经济结构进一步加强。1978 年以来的经济改革首先在微观个体进行，农业和农村改革的成功，缩小了工农之间、城乡之间的二元差异，1978~1984 为二元结构的减弱期。1985年开启了城市改革，随之城市经济高速增长，但农业增长放缓，二元经济结构再次加强。无论是从农业与非农业比较劳动生产率还是从二元对比系数来看，我国二元经济结构强度虽有所缓和，但十分缓慢。由于第三产业发展滞后影响了中国就业结构的转换，而城市化滞后导致城乡差距进一步扩大，因此，要进一步推进中国的二元经济结构转换必需加速城市化发展进程，以带动第三产业的发展，促进农村剩余劳动力向非农产业转移。
China’s dual economic structure, dating back to the mid-19th century, was strengthened after the foundation of People’s Republic of China owing to the adoption of the catching-up and surpassing strategies,which gave priority to heavy industry development. In 1978, the economic reforms was initiated in micro-economic units and the success in agricultural and rural reforms reduced the discrepancy between workers and farmers as well as the urban and rural areas, so the dual economic structure had been weakened during the period of 1978 to 1984. Since 1985 the cities’ economy had grown rapidly with the reform beginning in cities. However, the agricultural growth slowed down, which once again led to the strengthening of the dual economic structure. From then on whether it is from the view of the agriculture and non-agricultural comparative productivity or from the dual contrast coefficient, China’s dual economic structure has been eased, but very slowly. On one hand, the relatively slow development of the tertiary industry has affected the conversion of the employment structure. On the other hand, the urbanization lags behind the economic growth, which enlarges the difference between the urban and rural areas. Therefore, in order to promote the transformation of China's dual economy it is essential to accelerate urbanization, for it can spur the development of the tertiary industry as well as the transfer of the surplus agricultural labor force to non-farm jobs.
经济结构调整对劳动力市场需求的影响
The Impact of the Economic Restructuring on the Demand of the Labor Market  [PDF]
郭锦川, 李琼
Modern Management (MM) , 2011, DOI: 10.12677/mm.2011.14049
Abstract: 经济结构调整和劳动力流动壁垒动态地改变了劳动力市场的需求和供给，由此成为分析就业最重要的市场约束条件。由于各种内因和外因作用，高耗能、高投入的增长方式难以为继，中国经济结构调整已迫在眉睫。本文将我国所进行的非均衡结构转变做了归纳，讨论了产业结构变化、外贸变化、城市化、收入增长变化和人口结构变化对劳动力市场需求的影响。具体而言，中国三次产业结构正向“三、二、一”转变，农业人口中仍有大量劳动力需要向其他产业转移，低端制造业由于外贸萎缩与生产成本上升，处境艰难，第三产业对劳动力需求旺盛。城市化进程推动了城市建设、公共服务、基础设施以及金融服务、高端制造、软件设计等行业发展，对劳动力的需求也将相应变化。收入水平提高，必然会导致相应的消费结构变化，家电、通讯消费升级，对该行业的劳动力需求也同步增长。老年人口比例逐步增加，会对老年服务行业的相关企业的市场需求产生积极影响，进而影响其劳动力需求。随着经济结构调整步伐加快，劳动力也需不断提高其素质和技能水平，以满足市场需求。
The economic restructuring and barriers to labor mobility are the most important market constrains when it comes to analyzing employment for they dynamically change the demand and supply of the labor market. Due to various internal and external factors the economic growth, featuring high energy consumption and high investment, is becoming unsustainable, so the economic restructuring is pressing. This article summarized the non-equilibrium structural changes in China and discussed the impact on the labor demand of the changes in industrial structures, foreign trade, urbanization, income growth and demography. To be specific, as the structure of three industries is moving forward to “three, two, one”, a large number of surplus labor in agriculture needs to be transferred. The low-end manufacturing is struggling because of shrinking foreign trade and soaring production cost, but the service industry has a large demand for labor force. Urbanization promotes city building, public services, infrastructure construction, financial services, high-end manufacturing, software design and other industries. The income growth inevitably leads to corresponding changes in consumption structure. For example, the consumption of household appliances and communication devices upgrade. The demand for the elderly services will also develop with the aging of the population. All these changes will exert impacts on the demands for the related labor markets. As the economic restructuring accelerates, laborers also need to improve their quality and skills so as to meet the requirements of the labor markets.
大学毕业生抱负资本经济价值的微观计量分析
The Microanalysis of the Economic Value of College Graduates’ Ambition Capital  [PDF]
倪雪川
Finance (FIN) , 2011, DOI: 10.12677/fin.2011.11005
Abstract: 在调查问卷搜集所得数据的基础上，本文意图通过描述性统计分析和Logit模型定量研究抱负资本的积累效应对大学毕业生人力资本经济价值的影响，着重分析抱负资本与大学毕业生获取高收入可能性之间的量化关系。本文研究的结果表明，在其他条件相似的情况下，大学生抱负资本积累程度的不同会直接影响到其实现未来价值的可能性和获得高收入的概率。
Based on the data collecting by questionnaires, this paper intends to analyze the accumulation effect of ambition capital on the economic value of college graduates’ human capital through descriptive analyses and quantitative econometric method—the Logit model. And this paper particularly focuses on the quantitative relationship between a college graduate’s ambition capital and the likelihood he could get a higher than average salary. Under similar conditions, this paper proves that the different levels of accumulation in ambition capital will directly affect a college graduate’s likelihood to achieve his future value and the possibility he could gain a higher than average salary.
基于劳动力市场分割视角的农民工就业研究
A Study on the Employment of Migrant Workers Based on Labor Market Segmentation Theories  [PDF]
李琼, 郭锦川
Modern Management (MM) , 2011, DOI: 10.12677/mm.2011.13033
Abstract: 随着经济高速发展和城市化进程加快，日益庞大的农民工群体已成为中国产业工人的主要组成部分。但是，他们在城市的就业和生活却遭遇到各种歧视，受到不公平待遇。本文从劳动力市场分割视角讨论农民工的就业和工资情况。统计表明在职业分布上农民工主要在城市非正规部门从事“蓝领”等工作，工资低廉，而且社会和劳动权益保障方面非常薄弱。将农民工和城镇职工的工资差异进行分解发现，就业岗位间工资差异和就业岗位内工资差异中，主要差异由技能引起的，其次是由制度歧视引起的。因此，要改善农民工的经济状况，政府尽可能地消除劳动力市场分割对农民工就业的不利影响，逐步剥离城市户籍上的福利成分，也应适当提高最低工资标准，提供教育培训机会，加大农民工的人力资本投入，提高农民工就业质量。
As China’s economy grows rapidly and urbanization accelerates, the increasingly larger group of migrant workers has become a major component of industrial workers. However, they have suffered from various forms of discrimination and unfair treatment in employment and life. This article made a study on the employment and wages of migrant workers based on labor market segmentation theories. Statistics show that migrant workers are mainly engaged in “blue-collar” work in the urban informal sectors with low wages. Besides, social and labor rights protection for them is very weak. Decomposition of wage discrepancy between migrant workers and urban workers indicates that above half differentials are caused by skills differences and the left are caused by systematic discrimination either in terms of wage differentials between jobs or within jobs. Therefore, in order to improve the economic situation of migrant workers, the government should eliminate the adverse effect of the segmented labor market on the employment of migrant workers.

Abstract:
为了探讨大学生孤独感与社交焦虑之间的关系，本研究采用了UCLA孤独量表和交往焦虑量表(Interaction Anxiousness Scale, IAS)对450名大学生施测。研究结果表明：1) 大学生的孤独感体验在性别、是否独生、生源地项目上呈显著性差异；2) 大学生的社交焦虑在性别和是否独生上存在显著性差异；3) 孤独感与社交焦虑呈正相关，且达到显著水平，孤独感对社交焦虑有正向预测作用。结论：高校心理健康教育工作人员应该正确对待大学生高孤独感群体，并及时给予调控，帮助他们走出孤独，并锻炼大学生的社交能力，培养良好的人际交往品质，促进大学生的健康成长。
To explore the relationship between loneliness and social anxiety of college students, we test 450 college students by using the UCLA loneliness scale and the social anxiety scale (Interaction An-xiousness Scale, IAS). The results showed that: 1) with respect to the sense of loneliness, there was statistical significance in the projects of sex, one-child and local institution; 2) with respect to the social anxiety, there was statistical significance in the projects of sex and one-child; 3) there was a significant positive correlation between the sense of loneliness and social anxiety, and the sense of loneliness was a positive predictor for social anxiety. The conclusion is: the college staff who work at mental health education should properly deal with the problem of students who have high lone-liness to help them get out of loneliness, exercise the social skills of university students, develop good interpersonal communication quality, and promote the healthy growth of college students.
权益法下长期股权投资的投资损失确认管见
段川川
财会月刊 , 2009,
Abstract: 　　《企业会计准则第2号——长期股权投资》规定，投资企业对被投资单位具有共同控制或重大影响的长期股权投资采用权益法核算。权益法下，长期股权投资的账面价值随着被投资单位的所有者权益变动而变动，在被投资单位进行期末收益（以各项可辨认净资产的公允价值为基础调整后的收益）汇总后，按持股比例确认投资损益，并对长期股权投资的账面价值进行调整，使长期股权投资的账面价值与应享权益保持一致。当前，对投资损失尤其是大于长期股权投资账面价值的投资损失的会计处理，存在着各种争议。现举例说明。　　例：A公司持有B公司30％的股权，采用权益法进行长期股权投资的核算。2007年12月31日，A公司长期股权投资的账面价值为120万元，其中投资成本100万元、损益调整20万元；长期应收款（无收回计划也不打算收回）的账面价值为30万元。2007年度，B公司发生巨额亏损，以可辨认净资产等公允价值为基础调整后的净亏损为530万元。2008年度，B公司以可辨认净资产等公允价值为基础调整后的净利润为70万元。A公司应分担的投资损失＝530×30％＝159（万元）。
Modelica语言及PSPICE软件在微型振动发电机的仿真研究中的应用
The Application of Modelica and PSPICE Software in the Si-mulation of the Micro Seismic Power Generator  [PDF]
张祖志, 龚川
Modeling and Simulation (MOS) , 2012, DOI: 10.12677/MOS.2012.11002
Abstract: 本文利用Modelica语言，对微型振动发电机的输出特性进行了建模和仿真研究。为验证仿真结果，基于等效电路法，在PSPICE软件中建立了微型发电机模型并进行仿真分析，最后对Modelica语言直接建模仿真的结果和等效电路法的结果进行对比和分析。仿真结果分析表明，两种方法的电压曲线的特征是一致的，幅度接近，差异主要来源于两者的仿真过程不同，Modelica语言是直接将电路方程处理为数学方程求解，而PSPICE软件是从电路状态出发进行仿真。
This paper conducted a modeling and simulation of the output characteristics of the micro-vibration genera- tor by the Modelica language. To verify the rationality of the simulation results, the author also made a comparison with the PSPICE software based on the equivalent circuit method. The simulation results showed that the characteristic of the voltage curves from these methods is consistent and the amplitudes are similar. The differences of the amplitude mainly come from the diversity of the simulation process. The Modelica language directly transfers the circle equations into the mathematical equations to simulation while the PSPICE software carries out the simulation from the circuit state.
