碩士 / 國立臺灣海洋大學 / 水產養殖學系 / 99 / An economic analysis of tilapia farming in Taiwan was studied to evaluate the effect of farming size and farming experience on the input intensity and the varied profitability of tilapia farming. Thirty-nine farms were maintained for further studying after carefully examining and excluding outliers. For this study two sets of variables were carefully determined. The first set was the biological type which consisted of stocking density (SD) and survival rate (SR) whereas the second set was the economic type which consisted of input intensity and varied profitability.
The type of multivariate statistical analysis was used which included multivariate analysis of Variance (MANOVA), Principal Component Analysis (PCA), Discriminant Analysis and Canonical Correlation . The Cobb-Douglas production function was further used to study the current status of Taiwan tilapia production system. As the result, only the farming size had a significant effect on the input intensity but neither the farming experience nor their interaction on that. In regard to the varied profitability, neither the main effects of the farm size and the farming experience are significant nor their interaction. Finally, the Cobb-Douglas production function analysis showed an increasing return to economy of scale which means that a doubling of all inputs will more than double output.
