If you want to make a budget, I suggest studying engineering management. Because the knowledge closest to the root budget is cost, economy, law, construction and structure in turn.
So far, no university has enrolled students as a major alone, but some majors include budget courses, such as finance, accounting, financial management and so on.
If you get good grades and want to learn professional budget knowledge, then consider finance.
Main courses of public finance: political economics, western economics, monetary banking, international economics, public finance, national budget, tax management, international taxation, state-owned assets management, etc. Usually, the institutions offering finance are the same.
Other accounting and financial management are very common majors in two universities.
