The methodology is Path analysis model. The objective is to study how
Index of Industrial Production (IIP) of five City-provinces in the
Southern in Vietnam effect each other on these City-provinces’ GDP.
How GDP of each City-province effects on Vietnam’s GDP. Results are
Vietnam’s GDP is positively indirectly effected by IIPs of Ho Chi Minh,
Binh Duong, Binh Phuoc, Tien Giang and is negatively affected by Tay
Ninh’ s IIP. Besides, while GDP and IIP of Tay Ninh have negative general
effect on GDP and IIP of other City-provinces and GDP of Vietnam, GDP
and IIP of Binh Phuoc have the strongest general effect on GDP and IIP
of other City-provinces and GDP of Vietnam. Next, GDP and IIP of Binh
Duong have the second strongest general effect, GDP and IIP of Ho Chi
Minh are the third strongest general effect, GDP and IIP of Tien Giang
have the smallest general effect on GDP and IIP of other City-provinces
and GDP of Vietnam. Therefore, we suggest that Tay Ninh should have a
specific support mechanism. In particular, promoting development of
science and tech in Ho Chi Minh to achieve the ""spillover effect"" to the
other four City-provinces.
