Abstract: Abstract:The grouper hatching industry has high-risk and high-profit characteristics, and needs a comprehensive assessment, such as biological, economic and technical factors during the business. The study designed suitable questionnaires in order to realize and collection the data about expenditure and revenue of grouper hatching industry and surveyed hatching farm by random, in Pingdong, Kaohsiung, and Tainan. The result will apply Cobb-Douglas production function, multivariate analysis of variance (MANOVA) and principal component analysis to gain influence factors of operating efficiency of hatching industry.As the result, a Cobb-Douglaps production function indicates production elasticities of grouper hatching industry was 1.47, showed the industry was increasing return to scale. It indicated that the spawn and feed were the major factors afficting profitability. Multivariate analysis of variance indicates the production cost and biological factors were obvious difference due to the legion and farm types. The result of the principal component analysis shows the stocking density is higher and production cycle is longer in Kaohsiung Pingdong, and the result in Tainan is reverse. Profitability is highr in Tainan then in Kaohsiung, and profit intensity of feed is better in Pingdong.
