Using data from CHNS-2009, this study analyzed private return of education in the segmentation of the Chinese labor market using theory of real option. Empirical results show that, compared with gender and districts, the urban- rural factor values has the least influence in the option value of educational investment but values most in the total value of educational investment. These seemingly contradictory results are consistent with the multiple segmentations of the Chinese labor market. This study suggests that supplying more educational opportunities for vulnerable groups should improve both education equity and education efficiency.

Using data from a survey on the Ph.D.s employment in 4 cities and 14 universities in 2007,this paper analyzed how marrital and motherhood status affected doctresses employment.The results showed that there was no apparent gender discrimination. The argument that it is extremely difficult for doctresses to get a job was overstated. There was no sufficient evidence supporting the argument that it is even harder for single doctresses to get a job since they might get married and have a baby soon after. However,the study found that a good marriage could promote the career development of doctresses.

Using post-graduates' employment survey date conducted by Chinese Academy of Science and Technology for Development(CASTED),Ministry of Science and Technology(MOST),China,this paper analyses the effect of the migration(including working outside hometown or city where they have studied) on the benefits of different types of job satisfaction empirically.Empirical results show that migration can improve non-economic job satisfaction of post-graduates significantly,but can not improve their economic job satisfaction significantly.That is to say,the decision of post-graduates' migration is mainly determined by non-economic benefits for short-term goal.This can explain the social phenomena such as northern floating and dwelling narrowness to some extent.

Using the data from "Employment Survey of Postgraduates",two important issues in job search theory are discussed in this article:efforts in job search and retaining wage.In accord with other international empirical results,our findings show that:(1) the greater the intensity of postgraduates' job search,the higher retaining wage they will get;(2) the intensity of job search and retaining wage both have significant effects on the starting salary of their jobs.

本文根据北京大学课题组于2007年6月在全国范围内的一项高校毕业生就业调查数据,借鉴国际上已有的相关实证发现,系统考察了高校毕业生保留工资的影响因素。实证结果发现,性别、年龄、生源地、家庭收入、学历层次、学校质量或者声誉以及学业成绩都是高校毕业生保留工资的显著影响因素。在前人研究的基础上,本研究还通过引入私人社会资本和组织社会资本的概念来分析它们对于保留工资的影响。实证结果发现毕业生的私人社会资本对于他们的保留工资有着负的显著影响,而通过校园生活积累的组织社会资本对他们的保留工资却有着正的显著影响。
