这是我的经济学研究生项目申请文书，我在毕业后准备回国工作，请根据我的文书撰写300单词我准备回国工作的原因：Personal Statement

In 2020, the COVID-19 pandemic imposed significant hurdles on the worldwide economy. I was astonished by the profound interrelation between the economy and the global landscape, as prominent economic institutions implemented strategies such as interest rate reductions and loan concessions to secure survival. Subsequently, I developed an interest in the fundamental reasons and aspired to examine the elements that could influence economic developments. Consequently, throughout my undergraduate studies, I engaged in numerous competitions, particularly in innovative domains such as digital currencies and artificial intelligence, which intensified my interest in economics. I realized that economics is multifaceted and flexible, accommodating various methods and sectors, ultimately coalescing into a significant catalyst for innovation and progress.

The intake of undergraduate knowledge has established a robust foundation in economics, and provided me with exceptional academic literacy. Microeconomics, as a theoretical framework, afforded me a vital perspective, facilitating my comprehension of how economic subject influence the market and attain optimal resource allocation. I also systematically mastered various economic theories, as well as studied market mechanisms, equilibrium prices, and different methods of regulating resource allocation, which promoted me to perceive economics from a more scientific standpoint. Moreover, Econometrics was an opportunity for me to initiate interdisciplinary integration. It imparted me the methodologies of empirical research and inspired me to incorporate statistical and programming thinking to address critical factors that are difficult to quantify. I constructed a model using Stata to investigate the correlation between housing rent and tenants' consumption, and attempted to introduce artificial intelligence algorithms to quantify irrational factors when analyzing the participants’ psychological factors. This made me realize that intricate economic issues often necessitate auxiliary support from other disciplines, and only by integrating disciplinary knowledge can a complete theoretical system be established.

Upon acquiring the ability to employ critical thinking to analyze issues from different viewpoints, I commenced my exploration of the unfamiliar territory of economics through practical application. By chance, I recommended myself to the professor of research method course instructor, became an audience of the doctoral research group meetings. Two years later, I fortuitously assembled an innovation project team and solicited assistance from the instructor. Faced with 60,000 pieces of data, I self-taught Stata code to efficiently and accurately process in batches. In the subsequent construction of regression models, the selection of variables became crucial. To ensure that this cross-border study contained fixed effects across three dimensions, I designed a multiple regression equation and assessed the robustness using instrumental variables. The results demonstrated that the addition of fixed effects significantly enhanced the explanatory power, which served as the impetus for my further development. During the analysis, I also recognized that some factors may exert a greater influence on the model than others, and augmenting the weight of specific elements could produce more sensible outcomes. It indicated that there is a disparity between knowledge and practice, and I need to select appropriate theories based on the situation to guarantee the result's accuracy. This experience has bolstered my confidence in confronting complex phenomena, advanced my mastery of economic data analysis and modeling, and refined my capacity to adeptly employ statistical tools and economic theories.

If scientific research is the empirical verification of theory, then internships are the practical application of theory. Starting from the secondary market that is closely related to daily life, I first conducted two industry research internships. During my internship at Great Wall Securities, I focused on the secondary communication market and independently completed my first in-depth research report. I researched the product line layout and created a chart of equity structure; based on the needs of the upstream and downstream, I also inferred the potential market for the company and made a profit forecast. When dealing with the valuation model, I also searched for the market size of 5G and automotive intelligence, and made assumptions based on conditions such as gross profit margin. This 10 month internship has enhanced my comprehensive analytical skills from macroeconomics, industry dynamics to individual stock performance, allowing me to use a combination of technical and fundamental analysis to capture investment opportunities in market fluctuations. I did learn from this experience, though, that it could be challenging to fully grasp the industry's trends based solely on past data and present market performance. Therefore, I turned my attention to the primary investment market and deconstructed the enterprise value and investment potential from the source.

So, I chose the CICC Capital, and became an investment analysis intern. Compared to the secondary market, I realized that the primary market focused more on the long-term value assessment, capital flow, and commercialization capabilities of enterprises. Throughout the process of participating in due diligence and valuation analysis, I conducted a thorough financial and strategic evaluation. I collected data using Wind, computed the data using SQL formulae, and used tools like the DCF model and relative value approach. It was worth mentioning that in the investment decision for a certain brain interface, I believed that relying solely on financial data was difficult to fully reflect the true value of the enterprise. I therefore gathered current hazards and prospective markets from authoritative websites using my secondary market research experience. Successfully, I discovered that the pre-investment valuation was significantly higher than the market, and there were commercial and R&D risks involved. This experience has deeply impressed me that although the primary and secondary markets have their own focuses, they complement each other and together form the complete picture of the financial market.

My internship experience not only enabled me to master the core elements of the primary and secondary markets, but more importantly, it allowed me to cross market boundaries and integrate the advantages of both. I realize that the secondary market provides immediate feedback signals, while the primary market reveals intrinsic value and growth potential. Only by combining the two can we more accurately grasp the pulse of the market and make wise investment decisions. I believe that the Master of Economics program at the National University of Singapore (NUS) will provide me with an ideal platform to elevate my passion and experience to new heights. My goal is in the Applied Economics track, where I will focus on the practical application of economics. By supplementing the relevant cutting-edge scientific and technological means of artificial intelligence and big data, I will build a more advanced knowledge structure and ensure my career development prospects. At the same time, the program’s solid courses in economics, business and policy are indispensable, which will enhance my understanding of market and policy analysis.

Upon gaining enough expertise, I plan to explore the primary market and focus on investment analysis role in the future. I intend to acquire the VP position within five years, and I will master the team operation mode and cooperation approach. At that time, I will have the opportunity to engage in sophisticated strategic planning, which will enable me to obtain a more macro perspective. Ultimately, I am determined to establish a foundation that focuses on exploring potential investment opportunities and generating the maximum value returns for investors. I will uphold the principles of integrity, professionalism, and innovation, constantly pursuing excellence and success.
