  In recent decades, we have known some interesting applications of Lie theory
in the theory of technological progress. Firstly, we will discuss some results
of R. Saito in \cite{rS1980} and \cite{rS1981} about the application modeling
of Lie groups in the theory of technical progress. Next, we will describe the
result on Romanian economy of G. Zaman and Z. Goschin in \cite{ZG2010}.
Finally, by using Sato's results and applying the method of G. Zaman and Z.
Goschin, we give an estimation of the GDP function of Viet Nam for the
1995-2018 period and give several important observations about the impact of
technical progress on economic growth of Viet Nam.
