The study examines the relationship between government budget revenues and expenditures and inflation in Vietnam. Using a combination of qualitative and quantitative research methods, the research team demonstrates that state budget revenues and expenditures have a certain impact on the inflation rate in Vietnam during the period from 2005 to 2024. Annual data on government budget revenues and expenditures and the inflation rate (represented by the Consumer Price Index – CPI) were collected and analyzed using EViews 12 software. The regression results indicate the following: There is a positive relationship between government expenditure (CNS) and inflation, with a 1% increase in government spending leading to a 2.193227% increase in the CPI; There is an inverse relationship between government revenue (TNS) and inflation, with a 1% increase in government revenue leading to a 1.491342% decrease in the CPI; There is a positive relationship between budget deficit and inflation, with a VND 1,000,000 billion increase in the budget deficit resulting in a 0.974% increase in the CPI. Based on the research findings, the team proposes several policy recommendations for managing fiscal policy and stabilizing inflation, aiming toward overall macroeconomic stability.
