本研究利用台灣雲嘉地區養豬業之生產成本資料,利用迴歸分析探討台灣雲嘉地區一貫場、母豬場與肉豬場之成本結構。本研究結果顯示,不管是一貫場、母豬場或肉豬場,上市頭數對養豬成本都有正面且顯著影響;就一貫場而言,教育水準愈高,及批次場飼養方式均可降低生產成本;而批次場經營模式之生產成本亦低於傳統經營方式。在邊際成本方面,不論是一貫場、母豬場或肉豬場,批次管理之飼養成本均低於傳統經營模式,其中批次一貫場之飼養成本較傳統一貫場邊際成本低696元/頭;批次母豬場的飼養邊際成本較傳統母豬場低186元/頭;而批次肉豬場之飼養邊際成本比傳統肉豬場低806元/頭。另由本研究估算後發現,在各種不同上市規模下,批次場之獨占力程度均高於傳統養殖場,而相同經營模式下,規模愈大,獨占力程度越高,故以營運成本考量,批次管理經營方式應是未來養豬產業較佳的經營選擇。
The purpose of the study is to evaluate the production cost of pig farms in Taiwan. Set forth on their production cost and economic analysis approach. The production cost function, marginal cost function and Lerner’s degree of monopoly power are estimated for various type of pig farms. The estimated results show that marketed pig number has significantly positive impact on the production costs of farrow-to-finish, sow, and fattening. Adopting batch management lowers the production cost in farrow-to-finish as well. The marginal costs in batch management also generate lower marginal costs than those of traditional one. The marginal cost of farrow-to-finish with batch management is 696 NT/head lower than that with traditional management. The marginal cost of sow and fattening with batch management are 186 NT/head and 806 NT/head less than their counterparts. Our results also suggest the larger the marketed number of a farm, the higher the degree of monopoly power. With the same marketed sale, the batch management has higher Lerner’s index. According to the research findings, when the production cost is the main concern, the batch management is a better approach for the development of Taiwan’s Hog industry.
