Specialization introduction

Major introduction

See the world through data, mastering the core skills to extract value from massive information.

Program overview

Data Science and Big Data Technology is essentially about learning how to "pan for gold" in vast amounts of data. You'll learn to collect, clean, and analyze data, using machine learning, statistical models, and more to predict trends or make decisions. Core courses include Data Structures and Algorithms, Database Systems, Data Mining, Machine Learning, Python/R Programming, Distributed Computing (e.g., Hadoop and Spark), and Probability and Statistics. This major suits those who enjoy mathematical logic and don't mind programming—if you often wonder "why Douyin's recommendations are so accurate" or "how e-commerce knows what I want to buy," you'll likely enjoy studying it. Many Chinese universities (e.g., Tsinghua, Peking, Zhejiang University) invest heavily in this field, with dedicated big data labs and collaborations with companies like Alibaba, Tencent, and ByteDance, giving you access to real corporate data cases rather than just textbooks.

Major prospects

现在全球都在数字化，中国尤其跑得快——从移动支付到智慧城市，背后全是数据在驱动。企业需要有人帮他们理解用户行为、优化产品、降低成本，所以数据人才缺口很大。国际学生可以关注几个方向：一是跨境电商，比如SHEIN、阿里国际站，需要懂多语言用户的数据分析；二是金融科技，像蚂蚁集团、微众银行，用数据做风控和个性化推荐；三是智慧城市项目，比如交通流量预测、环境监测。中国的大数据产业已经形成生态，从底层技术（云计算、数据库）到上层应用（营销、医疗）都有机会。而且很多公司愿意招留学生，因为你们有跨文化视角，能帮他们拓展海外市场。

Career prospects

毕业后路子很宽。最常见的去处是互联网公司，比如百度、美团、滴滴，做数据分析师（分析用户行为，给业务提建议）或数据工程师（搭建数据管道，保证数据能高效处理）。金融行业也很吃香，银行、保险、证券需要数据科学家做风控模型或量化交易。咨询公司像麦肯锡、波士顿也会招数据人才做商业分析。薪资方面，在中国一线城市（北京、上海、深圳）应届生起薪大概15-25万人民币，有2-3年经验后能到30-50万，如果是算法岗可能更高。国际学生如果中文流利，留华工作不难；如果想回国，这个专业全球通用，比如新加坡、欧美也急需数据人才。另外，创业公司或自由职业也行，比如帮小企业做数据可视化或爬虫服务。
