SUMMARY
This project analyzes the impact of four key macroeconomic and market factors: supply
and demand, fuel prices, political–economic conditions, and weather/seasonal
factors, on the dry bulk import and export activities of Quang Ninh Ocean Shipping
Agency (VOSA Quang Ninh) on the European route during the period 2019–2024.
The study applies the ARDL (Autoregressive Distributed Lag) and ECM (Error
Correction Model) models to identify both long-term equilibrium and short-term
dynamics between these variables and the company’s business performance. The
research findings show that freight rate fluctuations, representing supply and demand,
have the strongest and most direct effect on the profitability of VOSA Quang Ninh,
indicating the firm’s sensitivity to changes in global maritime market balance. Exchange
rate volatility also has a significant impact, as revenues are mainly in USD while
operating costs are mostly in VND. In addition, changes in Brent oil prices increase
operational costs in the short term, while weather and seasonal factors cause
temporary disruptions in shipping schedules and port operations.
Based on these results, the study proposes six solution groups to enhance operational
efficiency and risk management capacity, including: improving supply and demand and
freight rate management; optimizing fleet operation and fuel consumption; managing
exchange rate and financial risks; improving adaptability to weather and seasonal
conditions; promoting management innovation and digital transformation; and
developing human resources and analytical capabilities.
The research contributes to a deeper understanding of how macroeconomic fluctuations
affect logistics enterprises in Vietnam and offers practical policy and managerial
implications for enhancing competitiveness and sustainability in maritime transport
operations.
