Abstract
This study has used minimizing input-oriented CRS DEA model with two output and five
input variables which use theory of technical efficiency. It mainly has used Nha Trang‘s
data (64 samples) to analysis, data from other areas in Khanh Hoa province (33 samples
in Ninh Hoa district, 33 samples in Van Ninh district, and 36 samples in Cam Ranh
district) only use to compare to Nha Trang to find the worst factors for technical
efficiency, improving these factors in section conclusion. All these data was collected
from data primary of Ph.D Pham Xuan Thuy when he did Ph.D thesis which he inquired
in Khanh Hoa province in 2004
There are 25% performances of Black Tiger Prawn (Penaeus monodon) DMUo is
efficient and 75% performances of DMUo are inefficient in Nha Trang city. We can put
to conduct for each of the inefficient. These are the units that management would focus
on to improve input factors or resource reduction.
Camparing among Cam Ranh, Nha Trang city, Van Ninh district, Ninh Hoa district the
propotion percent of Black Tiger Prawn (Penaeus monodon) DMUo technical efficient of
Cam Ranh is 42% due to georgapical advandtage. The propotion percent of DMUo
efficient of Nha Trang and Ninh Hoa is lowest because of nearly populated area and
processing factories.
