Technical efficiency analysis for commercial Black Tiger Prawn (Penaeus monodon) aquaculture farms in Nha Trang city, Vietnam
ForfatterHuy, Dang Hoang Xuan
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 proportion percent of Black Tiger Prawn (Penaeus monodon) DMUo technical efficient of Cam Ranh is 42% due to geographical advantage. The proportion percent of DMUo efficient of Nha Trang and Ninh Hoa is lowest because of nearly populated area and processing factories.
