台灣食品及飲料製造業市場結構－－行為－－績效關聯之研究－－兼論研發角色與不同時點比較

Structure-Conduct-Performance Relationships in Taiwan Food and Beverage Manufacturing Industry: Comparison in Different Survey Years and Roles of R&D

本研究主要在探討台灣地區食品及飲料製造業之市場集中度、廣告密集度與廠商利潤率的關聯，及其在不同時點是否有所轉變？並探討研發對此三者的影響關係。本研究建構計量經濟模型，並以1996 年及2001 年食品及飲料製造業廠商資料分析之。實證結果發現台灣地區食品與飲料製造業在1996 及2001 年之市場集中度、廣告密集度及廠商利潤率的關係有所轉變；研發對市場集中度及廣告密集度有正向的影響，但對廠商利潤率的影響不顯著。與相關文獻比較，可知台灣地區食品及飲料製造業之「結構－－行為－－績效」關係有別於整體製造業及其他國家的相同產業。因此政府部門對於此產業的輔導，宜注意其獨有的特色；廠商若能加強其研發，將有助於提高其市場佔有率。

This study is to explore relationships among concentration,advertising, and profitability of food and beverage industry in Taiwan,compare with their relationships in different survey year, and discuss theeffects of R&D on those variables. An econometric model was built up,and survey data of food and beverage firms were applied to estimatethose relationships. The results show that relationships amongconcentration, advertising, and profitability of food and beverage industryare different in 1996 and 2001. R&D has positive effects on concentrationand advertising, but it does not significantly affect profitability. Comparingto the related literatures, the relationships of “structure-conductperformance”are distinct from whole manufacturing industry in Taiwan,and those also differs from other countries. Thus if the government wouldwant to promote the development of this industry, it had better payattention to its unique characteristic. If firms could heighten their R&D,that could raise their market share.
