This study evaluates the factors affecting digital transformation for small and medium enterprises (SMEs) in Hanoi city. The research team determined the factors affecting digital transformation for small and medium enterprises based on some models such as the Theory of reasoned action (TRA), Technology Acceptance Model (TAM), Theoretical of planned behavior (TPB), C-TAM-TPB model and Unified Model of Technology Adoption and Use. The research results identify the model of factors that affect the argument transformation SMEs in Hanoi city, including (1) Perceived usability; (2) Perceived behavioral control; (3) Social influence; (4) Expected efficiency, (5) Convenient conditions and (6) Risks existing in digital transformation. The results also show that there are 6 factors affecting the implementation of the credit union of SMEs in Hanoi city, of which 5 factors have positive effects and 1 factor has negative effects. In addition, the results also show that there are certain differences in the intentions and decisions of digital transformation between different types of enterprises.

In this article, the research team uses the VAR self-regression vector model to evaluate the impact of exchange rates on inflation and economic growth in Vietnam over the period 2005-2018. With six endogenous variables included in the VAR model: bilateral real exchange rate (Er), money supply (M2), exports (X), imports (IM), GDP at 2010 comparative prices (GDPR), the consumer price index (CPI) and the two exogenous variables, international price (Pw) and US Federal Reserve interest rate (Ifed), the research team examines the impact of exchange rates on endogenous variables in the model and considers the reaction of inflation and economic growth on various shocks. Based on the quantitative results, the research team will recommend some discus-sions to contribute for the improvement of Vietnam's macro environment, trade balance, inflation control, and economic growth support; implementing the goal of macroeconomic stability to suit the period of international economic integration and improving national competitiveness.

The problems of the foreign exchange market and the global financial crisis, the European public debt crisis in 2008-2011 made the economy of Vietnam facing many macroeconomic instabilities. The escalating inflation in 2008 and 2011 posed many challenges for macroeconomic management, especially controlling inflation in Vietnam. The realization of macroeconomic stability and inflation control at a reasonable level from 2012 in Vietnam was assessed to bring about remarkable results. In this article, the authors reviewed the studies of International and Vietnamese inflation, pointed out to the macroeconomic factors affecting inflation in Vietnam. At the same time, the authors used the VAR model to examine the impact of macroeconomic factors including money supply, credit, exchange rates, interest rates, real gross domestic product, international prices, inflation and give some discussions from the VAR model results.

The study examines the relationship between money supply and inflation in Vietnam in the period of 2005-2021. The relationship between money supply and inflation is addressed in economic theories and models and has been studied by many experts in different economies in different periods. To examine the relationship between money supply and inflation in Vietnam in the period of 2005-2021, the research team collected data on money supply and inflation rate, then analyzed this relationship during three periods of 2005-2011, 2012-2019 and 2019-2021. Next, the research team collected data on money supply (MS - total means of payment) and consumer price index (CPI), quarterly data from the first quarter of 2005 to the fourth quarter of 2021 and uses Eviews 8 software for analyzing. The research team uses a linear regression model to evaluate the impact of money supply growth (GMS) on consumer price index (CPI), a variable representing the inflation rate, of Vietnam during the research period. The model results support the view that money supply growth and past inflation are among the factors affecting inflation in Vietnam. From the research results and the actual money supply, the money supply growth rate as well as the inflation rate in Vietnam during the research period, the research team makes some policy recommendations to achieve the targets of supporting economic recovery, controlling inflation, stabilizing the macro-economy in Vietnam after the Covid-19 pandemic.

In this article, the research team systematized the theoretical basis of the monetary transmission mechanism and the impact of interest rate channel in monetary transmission mechanism by Mishkin's approach and used the vector error correction model (VECM) to test the impact of interest rate channel in the monetary transmission mechanism in Vietnam in the period 2005 – 2019. There were 8 endogenous variables included in the VECM model; namely Consumer price index (CPI); Gross domestic product (GDP) at constant 2010 prices (GDPR); Money supply (M2); Refinancing interest rate (ISBV); Average lending interest rate in VND (ILR); Bilateral real exchange rate (ER); Credit to the economy (CRE); VN-Index (VN-INDEX); and, 2 exogenous variables: world consumer price index (PW) and US Federal Reserve interest rate (IFED). The results have shown that: money supply had a clearer effect on average lending interest rate than refinancing rate; Interest rate channel was an important channel to transfer the impact of monetary policy on inflation; Exchange rate and interest rates channel influenced economic growth in Vietnam more strongly than credit and financial asset prices channel did. Besides, the model results also confirm that in Vietnam, inflation in the past played an important role in determining current inflation.
