After half a year's busy work, this

After half a year's busy work, this graduation thesis is coming to an end. As an undergraduate's graduation thesis, due to the lack of experience, it is inevitable that there are many inconsiderate places It is hard to imagine completing this paper without the supervision and guidance of the tutor and the support from the school. First of all, I would like to thank my mentor, Huang Jia. Miss Huang is usually very busy with her work, but she has given me careful guidance at every stage of my graduation thesis. His Academic Rigor and scientific research of the spirit is also I will never learn the model, and will positively affect my future study and work. Secondly, I would like to thank my counselor, teacher Li Qing. Teacher Li has always shown great care and help to our study life and thesis work, always telling us about the school's work at the first time And always inspire us to study and work hard. The smooth completion of this paper is also inseparable from the teacher's help. Then I would like to thank all the teachers of the university for laying the foundation of our professional knowledge of international trade and economics over the past four years. At the same time, I would also like to thank all the students, precisely because of your support and encouragement, the graduation project will be completed successfully. Finally, I'd like to thank my Alma Mater, Wuzhou University, for my four years of training. Thank you from the bottom of my heart!
