Recently, the collaborative paper "Teamwork and Human Capital Development" by Associate Professor Zhou Yu from the China Academy of Economics at Liaoning University, as the corresponding author, Professor Wang Chunchao from Jinan University, and Lecturer Xiao Aiping from Guangdong University of Finance, was officially published in the top labor economics journal, Journal of Human Resources (JHR). This article is the eighth paper published by teachers from the Department of Economics at Liaoning University in the past two years, following their publication in top international journals in various fields of economics such as RESTAT (1 article by Yu Miaojie), JDE (1 article by Yu Miaojie and Yin Lijuan each), JPubE (1 article by Chen Feng), JEMS (1 article by Gao Ming), JLE (1 article by Yang Zhe), and JET (1 article by He Chao). It is another landmark achievement in the construction of the "Double First Class" initiative, indicating a new breakthrough in the construction of the "Double First Class" discipline at Liaoning University. Thesis Introduction: This paper investigates how teamwork affects students' human capital accumulation in academic performance and personality traits. In a county in China, the experiment randomly selected primary school classes and formed teams within the experimental classes to complete team activities. Research has found that compared to control group classes without a team, the behavior of forming a team can significantly improve students' academic performance. Meanwhile, teamwork can also lead to changes in personality traits. The students in the experimental class scored higher in terms of conscientiousness, extroversion, openness, and neuroticism in the Big Five personality traits compared to the control group, but scored lower in terms of agreeableness. These results are consistent with psychological literature on personality trait changes when individuals receive performance motivation incentives, indicating that the experimental group of students were motivated to work towards better team performance. Therefore, forming teams and conducting team activities is an effective means to promote the accumulation of human capital in primary school students.
