Sibling Effect and Ethnic Groups' Difference:Using the Empirical Data of the 2001TEPS

The research target of this thesis is the merge data from 《Taiwan Education Panel Survey》,it aims at investigating the effect of number of siblings on the learning achievements.The paper also explores the differences between different ethnic groups.First of all,after examining the statistics information,it is found that the number of siblings and education accomplishment are adversely related.In addition,Mainlanders have the best social financial status yet got the lowest give birth rate;while aboriginals have the worst societal economic status but got more number of family members.Second,the paper uses the ordinary least square method to analyze data,it uses the regression analysis for the educational achievement with sibling numbers and other control variables.It is discovered that the influence of sibling is very recognizable.After controlling the socio-economic background variables,we can see that the learning achievement of Mainlanders are not better than the aboriginals.However, Aboriginal groups still significantly lagging behind other ethnic groups.At the same time, this thesis also uses ""Sibling with different sex"" as the instrument variable of ""Number of Siblings"".I have applied two stages of 2SLS method, aim to solve the problem of endogeneity of number of siblings.Third,I have done the multiple regression analysis through intermediary variables upon socio-economic background,other than discovering siblings'' crowd out learning opportunities,I further found out that parents tend to allocate resources on sons for private schools,whereas investment for daughters is on talent interest class,this might be the outcome for the anticipated return on investment.Aboriginals'' child living with their parents have the lowest percentage however they have the highest percentage that parents are alcoholism,this will both hinder the social capital for their children.And this would be one of the reasons that performance of aboriginals are worse than other ethnic groups.
