Technical efficiency of marine fish cage culture in Cam Pha - Quang Ninh: Data envelopment analysis approach

Abstract

     This research estimates technical, scale efficiency and its determinants of marine fish cage culture in Cam Pha - Quang Ninh by applying data evelopment analysis (DEA) approach based on cross sectional data of 56 household's farms in 2011. Regression analysis was used to investigate relationship between technical efficiency and its determinants as experience, the number of year schooling of fanner and evironmental area (dummy variable). The results showed that technical efficiency under constant return to scale and under variable return to scale as well as scale efficiency of marine fish cage culure in Cam Pha - Quang Ninh are 0,91; 0,94 and 0,96, respectively. The regression analysis revealed that techn'ical efficiency was influenced significantly by experience of famer and evironmental area.
