THE RELATIONSHIPS BETWEEN FOREIGN DIRECT INVESTMENT, STATE-OWNED INVESTMENT, PRIVATE INVESTMENT, IMPORT, EXPORT AND ECONOMIC GROWTH IN VIETNAM

A key component for economic growth is the foreign direct investment (FDI), which drew the attention of researchers worldwide. This study aims to examine the relationship between foreign direct investment (FDI), state-owned investment (SOI), private investment (PI), import (M), export (X) and Vietnam's economic growth (GDP) since the Renovation (1986) to now (2019). The Vector Autoregression Model (VAR) and Vector Error Correction Model (VECM) were utilized to realize the above-mentioned goals. The Johansen co-integration test confirmed that there exists a long-run relationship among the above variables. The Granger causal relationship test found one-way causal relationship from GDP to FDI and PI in the short-run. Besides, the similar causal relationship between export and GDP is confirmed. Also, the two-way causal relationship between PI and export in the short-run is also found in this study. In addition, the impact of a shock of SOI on GDP is more significant than that of an FDI or PI shocks on GDP. By contrast, the response of GDP to shocks of import and export seems are small. Finally, it is certain that FDI plays an essential role in Vietnam's economy.
