衡量消費者對區域性海洋漁業永續生態標章的需求

Measuring Consumer Demand for Regional Sustainable Eco-labeled Seafood in Taiwan

本研究應用選擇實驗(choice experiment) 問卷調查的方式，探討臺灣消費者對於區域性永續漁業生態標章的需求，分析消費者對以石斑魚、白蝦及透抽產品屬性(如收穫方式、產地、有無永續生態標章認證及價格) 的偏好。實證模型的設定以隨機參數Logit模型(random parameter logit model) 估計每位受訪者對各屬性的成分效用值(part worth)，並計算各屬性的相對重要性(relative important score)。實證結果顯示，針對石斑魚，受訪者較偏好野生捕撈、生態養殖及具有國內永續生態標章認證，各屬性以收穫方式被認為是最重要的屬性，永續生態標章屬性次之，價格屬性的相對重要性最低。對白蝦而言，則較偏好以生態養殖及來源為臺灣國產品，價格高低及有無生態標章並未呈現顯著偏好差異，產地屬性在各屬性中被認為最重要，其次為收穫方式，最不重視的為價格屬性。對透抽而言，受訪消費者較偏好野生網獲、國產品、有永續生態認證標章的產品，各屬性中，永續生態認證標章為最被重視的屬性，價格屬性次之，收穫方式及產地反而最不受重視。

 

In this paper, the authors extend the standard R&D endogenous growth model to incorporate a bargaining structure and consider the related R&D policies. We find that government policies and bargaining process could be potential sources of local indeterminacy. On a high-growth path, directly engaging in R&D activities and subsidizing R&D activities by government may not enhance economic growth. While on a low-growth path, directly engaging in R&D activities and implementing R&D subsidies may induce economic growth.
