标题:博士屯教育 | 放弃清华博士,我选择赴美读博

秉持尊重学生和家长隐私的原则,以下所展示的信息,已经去掉敏感和涉及知识产权的信息。

还有N多学术素材,由于知识产权或家长原因,不便公开,敬请理解。

本文作者S同学,来自一所985大学,数学和计算机专业,大学三年级,成绩优异年级第一。之前参与过英国和中国香港的金融实习项目。由于成绩优异,已经获得了报送清华大学博士研究生的资格(直博)。S同学有更好的学术梦想,希望可以未来在大学中任教,这样就需要海外留学履历。她决定放弃清华大学博士录取资格,选择赴美读研、读博的道路。为此,报名参加了美国名校科研的选拔。参加美国名校科研,增加学术背景,开拓视野,获得真知。

我们非常高兴地看到,学生在科研感受中写道:“这个项目使我的编程,数据分析和逻辑思维技能得到了提高,在这次旅行中,我不仅获得了经验,研究方法,友谊,还找到了我未来的发展方向。最重要的是与优秀的教授享受快乐时光。”

作为科研申请老师,我们想告诉每位参与美国科研的孩子,获得推荐信、科研证书、科研报告、科研履历,其实仅仅是美国科研的基础性收获。更为重要的是,学生通过与顶尖学者、专家的交流,树立了长期的学术目标,让学术能力伴随着生命的成长而发展, 让学术赞美生命!

美国科研就是背景提升,目标就是提高本、硕、博录取质量。

第一周

During this week, we mainly studied the literature retrieval and reading skills, data processing methods and the basic theory of regression models. Thanks to my undergraduate degree in finance and software engineering, I am familiar with this knowledge. I also help my friends within my ability. When installing the R language, I provide related links and study manuals for the students to use. As shown in Figure 1, Figure 2, and Figure 3.

本周,我们主要研究了文献检索和阅读技巧,数据处理方法和回归模型的基本理论。感谢我的金融和软件工程本科学位,我熟悉这些知识。我也在我的能力范围内帮助我的朋友。安装R语言时,我提供相关链接和学习手册供学生使用。

Research work is very tired. Because my undergraduate degree in the computer research group for more than a year, but do not learn about the economic and financial research fashion. The initial plan was to experience economy research and make a final decision on my PhD area of research. But on the way to American University, the domestic Mentor only gave me one day to make this significant decision. I decided to accept it after I fully thought about it. The main purpose of coming to Harvard is to experience the culture here and prepare for future exchange study during the PhD and post-doctoral work.

研究工作很累。因为我在计算机研究组的本科学位一年多了,但不了解经济和金融研究的内容。最初的计划是体验经济研究并对我的博士研究领域做出最终决定。但在前往美国大学的途中,国内导师只给了我一天时间做出这个重大决定。在我充分考虑之后,我决定接受它。来美国大学的主要目的是体验这里的文化,为博士和博士后工作期间的未来交流学习做好准备。

第二周

This week we mainly studied data processing, modeling and testing of R and Tata. In general, I can complete the teacher's task well and ahead of time. And share my resources with my friends.

本周我们主要研究了R和Tata的数据处理,建模和测试。一般来说,我可以提前完成老师的任务。并与我的朋友分享我的资源。

But I also encountered some difficulties. For example, I don't know how to deal with data (such as saliency) in economics. During my undergraduate computer research, data processing was completely another set of paradigms that could not be converted in time. Since I didn't understand it at the beginning, I chose the wrong variable based on the first attempt. However, under the guidance of professor, the experiment was re-run. I am currently working on paper writing.

但我也遇到了一些困难。例如,我不知道如何处理经济学中的数据(例如显着性)。在我的本科计算机研究期间,数据处理完全是另一套无法及时转换的范例。由于我一开始并不理解它,所以我根据第一次尝试选择了错误的变量。然而,在教授的指导下,实验重新进行。我目前正在写论文。

第三周

In this week, we mainly completed the writing of the first paper and the work of Project 3. In the process of writing a thesis, professor gave us many useful suggestions, such as the structure of the paper, the logic of writing, and so on. Under the guidance of professor, I successfully completed the writing of the first paper. And I am honored to receive professor's only paper guidance in class. professor pointed out that my paper structure is relatively complete, but there are some small details that still need to be improved, such as some tables that are slightly thin and can be merged. I am very grateful for his guidance and made corresponding changes, the final version is shown in Figure 1.

在本周,我们主要完成了第一篇论文的写作和项目3的工作。在撰写论文的过程中,教授给了我们许多有用的建议,比如论文的结构,写作的逻辑等等上。在教授的指导下,我顺利完成了第一篇论文的撰写。我很荣幸在课堂上获得教授唯一的论文指导。教授会指出我的论文结构比较完整,但仍有一些小细节需要改进,比如一些表稍微薄一些并且可以合并。我非常感谢他的指导并作出了相应的修改,最终版本如图1所示。

Besides, I wrote a review on the second project concerning overview, strengths, weakness, and additional comments, providing new ideas to this research.

此外,我写了第二个项目的评论,涉及概述,优势,弱点和其他评论,为本研究提供了新的想法。

We also finished the project 3: CMTO. This empirical project analyzes data from pilot studies conducted in partnership with the King County Public Housing Authority (KCHA) and the Seattle Public Housing Authority (SHA). Families willing to accept the severs from CMTO are randomly divided into control group and experimental treatment group. The results show that being randomly assigned to receive the treatment increases the probability of moving to a high opportunity neighborhood by 18 percentage points while treatment on the treated increases 23%. There is evidence of treatment effect heterogeneity by Public Housing Authority, and lack of evidence of treatment effect heterogeneity by family income.

我们还完成了项目3:CMTO。该实证项目分析了与金县公共住房管理局(KCHA)和西雅图公共住房管理局(SHA)合作进行的试点研究的数据。愿意接受CMTO服药的家庭随机分为对照组和实验治疗组。结果显示,随机分配接受治疗增加了移动到高机会邻居的概率提高了18个百分点,而对治疗的治疗增加了23%。公共住房管理局有证据表明治疗效果存在异质性,家庭收入缺乏治疗效果异质性的证据。

Next week is the last week of my research project. I intend to present to professor the idea that I hope to return to university as a PhD in the long run and even in the future. I know this is a difficult road, but I am still young, I have time and confidence to keep on going.

下周是我研究项目的最后一周。我打算向教授提出这样一个想法,即我希望从长远甚至将来回到大学攻读博士学位。我知道这是一条艰难的道路,但我还很年轻,我有时间和信心继续前进。

第四周

The fourth week was a tough but happy week. We had to complete the writing of the second paper in a week, which is not an easy job. Thanks to the applied econometrics courses I have studied before, I finished the task smoothly. Besides the panel VAR of the original paper, impulse response function analysis and variance decomposition, I added the ADF unit root test and cointegration test. I started to enter the experimental part from Tuesday. In order to draw a solid conclusion, I continued to test the relevant experimental content until Wednesday night. Although the ADF test results are very significant, the final cointegration test results have not been very satisfactory, and the data has a strong cointegration, which cannot be solved due to time limitation. It took another night to finish the paper and edit the layout two hours before the deadline.

第四周是艰难但快乐的一周。我们必须在一周内完成第二篇论文的写作,这不是一件容易的事。感谢我之前学过的计量经济学课程,我顺利完成了任务。除了原始论文的VAR,脉冲响应函数分析和方差分解外,我还加入了ADF单位根检验和协整检验。我从星期二开始进入实验部分。为了得出可靠的结论,我继续测试相关的实验内容,直到周三晚上。尽管ADF测试结果非常显着,但最终的协整测试结果并不十分令人满意,并且数据具有很强的协整性,由于时间限制而无法解决。又花了一个晚上才完成论文并在截止日期前两个小时编辑布局。

In the final review, professor showed two other students, basically only two or three pages of content without typesetting. In fact, I had doubts before, I had been very difficult to complete in a few days and took days and nights to work on it this week, why other students can easily complete. Although the version I finally submitted is also in a hurry, the conclusions are very rough, there are many places to improve the writing and content, but I can at least achieve the length, basic content, and typesetting requirements. However, my classmates also have a lot of places worth my learning. In the presentation, the other group showed the results of the post-grouping experiments that they achieved. This kind of experiment is very rare and worth learning. Our group highlighted future research proposal and time planning.

在最后的评论中,教授展示了另外两名学生,基本上只有两到三页的内容没有排版。事实上,我之前有过怀疑,我很难在几天内完成并在本周花了几天时间来完成它,为什么其他学生可以轻松完成。虽然我最终提交的版本也很匆忙,结论非常粗糙,有很多地方可以改进写作和内容,但我至少可以达到篇幅,基本内容和排版要求。但是,我的同学也有很多值得我学习的地方。在演示中,另一组显示了他们实现的分组后实验的结果。这种实验非常罕见,值得学习。我们小组强调了未来的研究提案和时间规划。

After the last lesson, we made a simple summary and goodbye. Everyone sincerely wished each other a promising future. After that, professor and I had a talk in the conference room of the economics department. professor encouraged me that realizing the dream of having a Ph.D. degree in the United States is still hopeful, although there may be difficulties. I expressed my most sincere gratitude to professor, as well as the desire to be in touch with in the future and to do some work for professor. In this trip, I not only gained experience, research methods, friendship but also found my future development direction. The most important thing is to enjoy a happy time with the excellent professor.

在上一课之后,我们做了一个简单的总结和再见。每个人都真心希望彼此前途光明。在那之后,教授和我在经济学系的教室进行了一次谈话,他鼓励我实现拥有博士学位的梦想。尽管可能存在困难,但美国的学位仍然充满希望。我对教授表示最诚挚的感谢,并表达了对未来保持联系并为教授做一些工作的愿望。在这次旅行中,我不仅获得了经验,研究方法,友谊,还找到了我未来的发展方向。最重要的是与优秀的教授享受快乐时光。

科研总结(节选)

I am appreciated that I have the opportunity to have the economic research experience at American University this summer. My professor proficient in teaching content, and thoroughly explained the courses (with depth). professor's course is associated with economic and financial disciplines, combined with computer technology, broadening the way of thinking (with broadness). Professor introduced novel developments and new achievements of this discipline, giving us as much information as possible, as well as the introduction of the trend and prospects (with density).

我很感激,我有机会在今年夏天在美国大学获得经济研究经验。我的教授将精通教学内容,并彻底解释课程(深度)。教授的课程与经济和金融学科相结合,与计算机技术相结合,拓宽了思维方式(具有广泛性)。将介绍该学科的新发展和新成果,为我们提供尽可能多的信息,以及趋势和前景的介绍。

Empirical Research on Financing Constraints and Investment Behavior of Chinese Listed Companies: China's financial system is undergoing reform and innovation in the financial system during the transition period. However, the marginal capital-output rate has risen sharply in recent years, indicating that China's capital or financial efficiency is deteriorating. We use a VAR model to analyze the impacts fundamental factors of marginal productivity on Tobin Q with a panel data of listed companies of China from 1997-2008. The results show that the availability of internal funds is more important in explaining investment as well as the evidence of inefficient allocation of capital and that slower growth rates in China. This paper provides microscope insights for further deepening reform of China's financial system.

中国上市公司融资约束与投资行为的实证研究:转型期中国金融体系正在进行金融体制改革与创新。然而,近年来边际资本产出率急剧上升,表明中国的资本或金融效率正在恶化。我们使用VAR模型分析了托宾Q边际生产力的影响因素,以及1997 - 2008年中国上市公司的面板数据。结果表明,内部资金的可用性对于解释投资以及资本配置效率低下和中国经济增长放缓的证据更为重要。本文为进一步深化中国金融体系改革提供了显微镜见解。

Besides, the projects K given trained my programming, data analysis, and logical thinking skills. In project 1, we explored the upward mobility through data analysis and data visualization. We found the pooling average upward mobility of San Francisco (38405.54) is higher than the atlas's (34311.68) and children from low-income families do well generally have better outcomes for those from high-income families. In project 2, we checked whether the class size has an impact on students score by data plot with threshold and regression analysis. In project 3, we conducted an empirical project to analyze data from pilot studies conducted in partnership with the King County Public Housing Authority (KCHA) and the Seattle Public Housing Authority (SHA). Families willing to accept the severs from CMTO are randomly divided into the control group and experimental treatment group. The results showed that being randomly assigned to receive the treatment increases the probability of moving to a high opportunity neighborhood by 18 percentage points while treatment on the treated increases by 23%. There is evidence of treatment effect heterogeneity by the Public Housing Authority, and lack of evidence of treatment effect heterogeneity by family income. In project 4, we use variables from Google DataCommons to predict intergenerational mobility using machine learning methods. The measure of intergenerational mobility that we will focus on is the mean rank of a child whose parents were at the 25th percentile of the national income distribution in each county (kfr_pooled_p25). My goal is to construct the best predictions of this outcome using other variables, an important step in creating forecasts of upward mobility that could be used for future generations before data on their outcomes become available. We found Random Forest performed the best in this dataset. Random Forest has many strengths: on many current datasets, it has great advantages over other algorithms and performs well; it can handle very high dimensional (feature a lot) data, and no need to make feature selection (Feature subsets are randomly selected); After the training, it can give which features are more important; When creating a random forest, the generalization error without bias estimation and the model generalization ability is strong.; Training speed is fast, easy to make parallelization method; In the training process, can detect the interaction between the features; The implementation is relatively simple; For unbalanced data sets, it balances errors; If a large part of the features is lost, accuracy can still be maintained. However, Random forests have been proven to be over-specified on some noisy classifications or regression problems; For data with different values, attributes with more values will have a greater impact on random forests, so the attribute weights generated by random forests on such data are not credible. Therefore, we need to test it on other latest upgraded models (i.e. LightGBM or deep neural network), and we can also propose a novel to improve the performance.

此外,K老师项目训练了我的编程,数据分析和逻辑思维技能。在项目1中,我们通过数据分析和数据可视化探索了向上移动性。我们发现旧金山的汇集平均向上流动性(38405.54)高于地图集(34311.68),而来自低收入家庭的儿童通常对高收入家庭的人来说效果更好。在项目2中,我们通过阈值和回归分析的数据图检查班级规模是否对学生得分产生影响。在项目3中,我们进行了一个实证项目,以分析与金县公共住房管理局(KCHA)和西雅图公共住房管理局(SHA)合作进行的试点研究的数据。愿意接受CMTO服药的家庭随机分为对照组和实验治疗组。结果显示,随机分配接受治疗增加了移动到高机会邻居的概率提高了18个百分点,而对治疗的治疗增加了23%。公共住房管理局有证据表明治疗效果异质性,而家庭收入缺乏治疗效果异质性的证据。在项目4中,我们使用来自Google DataCommons的变量来使用机器学习方法来预测代际移动性。我们将关注的代际流动性衡量标准是一个孩子的平均等级,其父母在每个县的国民收入分配的25%(kfr_pooled_p25)。我的目标是使用其他变量构建对此结果的最佳预测,这是创建向上移动性预测的重要步骤,可以在其结果数据可用之前用于后代。我们发现随机森林在这个数据集中表现最好。随机森林有许多优点:在许多当前的数据集中,它比其他算法具有很大的优势,并且表现良好;它可以处理非常高维(特征很多)的数据,而不需要进行特征选择(随机选择特征子集);培训结束后,它可以提供哪些功能更重要;在创建随机森林时,没有偏差估计的泛化误差和模型泛化能力很强。训练速度快,易于制作并行化方法;在训练过程中,可以检测到特征之间的相互作用;实施相对简单;对于不平衡的数据集,它可以平衡错误;如果大部分功能丢失,仍可保持准确性。然而,已经证明随机森林在一些嘈杂的分类或回归问题上被过度指定;对于具有不同值的数据,具有更多值的属性将对随机森林产生更大的影响,因此随机森林对此类数据生成的属性权重不可信。因此,我们需要在其他最新升级的模型(即LightGBM或深度神经网络)上进行测试,我们还可以提出一种新颖的方法来改善性能。

In sum, thanks to professor again for cultivating an academic aptitude for independent thinking and an interest in economic research.

总之,再次感谢教授培养了我独立思考的学术才能和对经济研究的兴趣。

She was a highly engaged and active learner. In our program, I mainly introduced data processing, modeling and testing of R. Miss. S could always complete the tasks I assigned ahead of time, in a high quality. Also, she never hesitated to share her resources with her peers. Miss. S also impressed me deeply with her enthusiasm in academic discussions. For example, while processing economic data, she was confronted with an urgent problem. Despite of continuous efforts, she failed to solve the problem. Thus, she turned to me for guidance. Her open mind enabled her to solve most problems creatively.

可以提前完成我提前分配的高质量任务。此外,她毫不犹豫地与同龄人分享她的资源。也对她在学术讨论中的热情深深印象深刻。例如,在处理经济数据时,她遇到了一个紧急问题。尽管不断努力,但她未能解决问题。因此,她转向我寻求指导。她开放的思想使她能够创造性地解决大多数问题。

Miss. S's final research was concerned to the financing constraints and investment behavior of Chinese listed companies. During the process, Miss. S excelled from a cohort of participators of our program. The structure of her paper was complete, and the logic of writing was very clear. In this project, she adopted a VAR model to make analysis, which was always comprehensive, including strengths, weakness, and additional comments as well as new ideas to the research. It was quite challenging but Miss. S worked it out with her academic intellect and independent thinking ability.

S小姐的最终研究涉及中国上市公司的融资约束和投资行为。在这个过程中,沈小姐从我们计划的一群参与者中脱颖而出。她的论文结构完整,写作逻辑非常明确。在这个项目中,她采用VAR模型进行分析,该分析始终是全面的,包括优势,劣势和其他评论以及研究的新想法。这是相当具有挑战性的,但是沈小姐以她的学术智慧和独立思考能力来解决这个问题。

During the program, Miss. S communicated with me frequently. She was quite clear about her academic interest, and expressed her ideas about pursuing a master degree. Her enthusiasm and dedication along with various notable abilities undoubtedly qualify her potential in furthering her study and research.
