TA来自北京，参加美国哈佛大学科研收获分享

　　ZL同学，品学兼优，来自北京一所985高校，经济学专业。学生有更高的梦想，希望本科毕业后能够到美国名校读研究生。为此，参与了美国名校科研，增加学术背景，开拓视野，获得真知。

　　通过美国名校科研老师的指导，申请到了美国大学的科研机会。本文是学生在美国大学科研学习期间所写的感受，真实、自然。

　　由于学生临近申请季，国内的大学课程紧张，没有时间赴美科研，选择线上指导。美国科研申请老师，特意与哈佛大学老师沟通，安排正常的科研指导外，还安排1名助教为学生辅导作业，在科研结束后，学生不仅收获推荐信、科研证书、科研履历，还顺利发表学术论文一篇。

　　在学生的科研感受结尾处，附录了学生的科研笔记、科研论文、推荐信文稿，供学生、家长参考。

　　The experience of researching for one month with Harvard University professor is unforgettable. The mentor always offers us help with his patience in the realm of doing research. Firstly, he gave us four papers involving the investment behavior and the financial development. He commanded us to read literatures and learn something new that I never get in touched with before. In the first meeting on line, my mentor told us our final target of this project. In the next meeting, my mentor leaded us to analyze the structure of the article, imparted to us about the information contained in the article.

　　与哈佛大学老师一起研究一个月的经历令人难以忘怀。 老师总是在研究领域为我们提供帮助。 首先，他给了我们4篇涉及投资行为和金融发展的论文。 他命令我们阅读文学，学习一些我以前从未接触过的新东西。 在第一次科研指导中，我的老师告诉我们这个项目的最终目标。 在接下来的课程中，我的老师带领我们分析了文章的结构，并向我们传授了文章中包含的信息。

　　Through the PowerPoint based on the paper which is created by Love in 2006, teacher let us comprehend what is the Neoclassical theory of investment, Arrow-Debreu framework and Asymmetric information. I do not know well about the economic model before, then mentor just introduce some rudimentary knowledge about the mathematical modelling for our better understanding of getting an obvious conclusion through a model. Then he explained the sources of data and tell us how to obtain the ideal data from different kinds of websites accurately and swiftly. The variables used in the article is novel for me, so teacher gradually explained where these variables came from and why did we use these kinds of ratio but not the absolute value.

　　通过基于2006年Love创建的论文的PowerPoint，教师让我们理解什么是新古典投资理论，Arrow-Debreu框架和非对称信息。 我之前对经济模型了解不多，那么老师只是介绍一些关于数学建模的基本知识，以便更好地理解通过模型得出明显的结论。 然后他解释了数据来源，并告诉我们如何准确，迅速地从不同类型的网站获取理想数据。 文章中使用的变量对我来说是新颖的，所以老师逐渐解释了这些变量的来源，为什么我们使用这些比率而不是绝对值。

　　In the next meeting, mentor told us the method of using STATA and process data with software. What is more, he told us what was the meaning of different kinds of variables value created by scheduled procedure. STATA finally will create graphs with the aim of enabling us to draw a more intuitive conclusion. Mentor finally analyzed every graph and told the implication to us. When we do our final research and hand in our assignment, teacher guided us to run the process we had created, and leaded us to finish the final draft according to the article written by Love.

　　在接下来的科研指导中，老师告诉我们使用STATA和使用软件处理数据的方法。 更重要的是，他告诉我们由预定程序创建的不同类型的变量值的含义是什么。STATA最终将创建图表，目的是使我们能够得出更直观的结论。 老师终于分析了每一张图并告诉了我们这个含义。 当我们进行最后的研究并完成任务时，老师指导我们运行我们创建的过程，并引导我们根据Love撰写的文章完成最终草案。

　　Through the study of one month, I gradually become mature about the scientific research. Previously I do not know about how to accomplish a study. Now I Know that an eminent research must go through hardworking. One has to read thousands of articles first, then find data that suits his research direction. At the same time, he should be versed in mathematical modelling for exploring the nature of the research clearly. What is more, he should learn some knowledge of computer programming to deal with the data and finally obtain the satisfied conclusion through his own analyzing. If one masters the abundant knowledge of mathematical, economics and computer, he may make a difference in scientific research.

　　通过一个月的研究，我逐渐走向成熟的科学研究。 以前我不知道如何完成一项研究。 现在我知道一项杰出的研究必须经过努力才能完成。 首先必须阅读数千篇文章，然后找到适合他研究方向的数据。 同时，他应该精通数学建模，以便清楚地探索研究的本质。 更重要的是，他应该学习一些计算机编程知识来处理数据，最后通过他自己的分析得到满意的结论。 如果掌握了丰富的数学，经济学和计算机知识，他就可以在科学研究中发挥作用。

　　During this period, there was a selfless teaching assistant who taught us the theory research method. His content was based on the Investment textbook. I am a student whose major is economics, so I am not proficient in the realm of finance. Through his theory classes of investment, I mastered a good deal of financial terms, the fundamental operation of financial development. The class enriched my financial knowledge, I think it will contribute to my further study, so I am grateful to the assistant for broadening my horizons.

　　在此期间，有一位无私的助教教我们理论知识。 他的内容基于投资教学的书籍。 我是一名主修经济学的学生，所以我不擅长金融领域。 通过他的理论投资指导，我掌握了大量的财务条款，金融发展的基本运作。 这堂课丰富了我的金融知识，我认为这将有助于我的进一步学习，所以我很感激助理拓宽了我的视野。

　　I have learned a lot through the research experience, I think it will be a rewarding experience for me to keep moving forward on the road to financial learning and researching!

　　通过这段时间的金融学科研，我学到了很多东西，我认为在金融学习和研究的道路上继续前进对我来说将是一次有益的经历!

　　推荐信文稿(部分)：

　　During the program, Mr. Liu initiated a research project named Factors affecting the investment of listed companies in China: Evidence from panel VAR. From selecting the topic at the beginning, to reading academic journals on listed companies and panel VAR, collecting the data, writing reviews and making the presentation PPT, Liu was an active participant throughout the process, presenting earnest and inquiring attitude. The data they collected during the process integrated the main financial index and governance structure index of the two databases. By using Stata, they have treated the data with a more methodical and rigorous attitude. In the final presentation, Liu displayed good logical thinking, confidence and oral defense skills, which assured a good result for the speech. His presentation was spoken highly of not only by me, but also all the fellow students.

　　On top of that, I was more than glad to witness Mr. Liu rapid growth in academic research capability. As I mentioned, he has conducted a presentation on investment of listed Chinese companies using VAR. They eventually generated an academic paper, at the end of which, he clearly listed all the cited articles and journals, which well demonstrated his academic rigor, as well as satisfying literature-reading capability. Through reading his paper, I believe that his findings contributed to the financial constraints and investments decisions by separating fundamental factors and financial factors that influence the investment. Specifically, impulse-response functions allowed people to obtain more obvious evidence of the importance of financial factors. Therefore, I believe that his paper could be applied to further exploration on the factors that influence the investment decisions made by enterprises. Also, such achievements have well satisfied my expectations for an undergraduate student, and I believe Mr. Liu could keep forging forward to greater progress.
