果菜批發市場為一需兼顧公益及私利的經營單位,其主要收入來源僅為固定費率之管理費收入。在費率受限於「農產品批發市場管理辦法」規定,無法調升下,唯有盡量降低經營成本,並另闢財源,以彌補財政上入不敷出的窘境。 本文以台北農產運銷公司為例,透過結合價值鏈與最適整合階段的概念,分析探討果菜批發市場是否能藉由水平與垂直整合相關業務,進一步降低其平均成本。利用1997-2002年月別資料進行實證研究,實證結果顯示,台北農產運銷公司水平經營台北市第二果菜批發市場,可因享有規模經濟,使平均成本由水平整合前每公噸541元降為水平整合後每公噸531元。若同時垂直經營停車場、冷藏庫與供銷服務中心等相關業務,可使台北農產運銷公司獲利上升,累減成本下降。累減成本可進一步由每公噸531元依序降為519元、513元、486元。
The present study aims to incorporate the concept that combines the value chain with the optimum degree of vertical integration and to use the econometric model to further analyze how the average cost of Taipei Agricultural Products Marketing Company changes after it horizontally integrates The Taipei Second Fruits and Vegetable Wholesale Market and vertically integrates parking lots, cold storages, and the the packing of fruits and vegetable The results have shown that if only Taipei Agricultural Products Marketing Company is operated, the average cost is NT541 per ton; if Taipei Second Fruits and Vegetable Wholesale Market is horizontally integrated and operated, the average cost decreases to NT531 per ton because of economies of scale; if it vertically integrates parking lots, cold storages as well as the packing of fruits and vegetable, degressive average cost decreases further to NT519, NT513, and NT486 per ton due to the fact that these value activities can continue to create profits.
