碩士 / 國立臺灣海洋大學 / 應用經濟研究所 / 102 / The milkfish is the main species in Taiwan’s aquaculture and its production ranked second in the consumption markets in 2012. Besides, the aquaculture area of the milkfish was 11,438 hectares and accounted for 21.91% of the whole farming area in Taiwan in the same year. The milkfish industry which significantly impacted on Taiwan’s fisheries was also on the early harvest list of ECFA.
This thesis introduced aquaculture and milkfish industry in Taiwan. We observe many spreads in different markets. The spread between distributor’s purchasing price and sales price are known as the distributing margins; the spread between wholesaler’s purchasing price and sales price are known as the wholesaling margins; the spread between retailer’s purchasing price and sales price are known as retailing margins. In this study, we will simply call these players operators and define the ‘market margins’ as the spread between the production price and the consumption price.
This study references the regression model in Schroeter and Azzam (1991) to understand the market margins in Taiwan milkfish industry through separating the market margins into four elements: marginal processing cost, oligopoly and oligopsony price distortions, and output price uncertainty. We use the local date from 2000 to 2012.
Empirical results show that the origin of milkfish market structure is perfectly competitive market while the retail market is not perfectly competitive market structure. The Lerner Index is 0.8803, indicating milkfish market provider has bargaining power for the retail market. The average of the market margin in the milkfish industry in Taiwan is 9.3183 yuan spread / kg, and the average marginal cost is -4.4246 yuan / kg, accounts for -47.48% current spreads. The oligopoly power is 43.0068 yuan / kg, which accounts for 461.53% of the spread. The average risk of output price uncertainty is 1.1033 yuan / kg, accounting for 11.84% of the profit spread. Wages, shipping fee, ice cost and retail prices are the factors that impact significantly on the market spreads.
Key Words： market margins, ECFA , market structure, price risk elasticity.
