摘要

將屏東地區之漁業視為農業經濟體系中的一個產業來看，並且把漁業分成養殖漁業，近海漁業以及沿岸漁業三大項。以投入——產出模式建立產業間之關聯係數表，並且以李昂提夫逆矩陣分析產業之間的聯鎖關係。分析結果歸納如下：1．屏東地區之漁業中，以鮪延繩釣漁業最為重要。2．漁業之區域商數大於1.0，卽屏東縣之漁業，比之於全省來說，更具有地區性及集中性。3．屏東地區漁業之原始投入約為中間投入之4倍左右，意味着對漁業的投入以原始投入佔絕大部份。4．屏東地區漁業之影響度指數以及感應度指數均小於1.0，卽漁業增產的結果，對於其他產業之影響效果低於平均水準。5．屏東地區漁業之向後聯鎖均勻度指數小於其他產業，其中間投入比較均勻分佈於其他產業。6．屏東地區漁業之向前聯鎖均勻度指數大於其他產業，其產品之分配比較集中於少數產業。

In Pingtung County fisheries are considered as an industry of agriculturaleconomic structure.They are divided into three sectors;aquacultural,inshorefishery and coastal fishery.Input-output analysis is used to establish theimpact coefficient matrix.Based on Leontief Inverse Matrix,the results ofinterindustrial linkage analysis are discussed in this paper.The results are as follows:(1)Tuna longline fishery is the most important fishery in Pingtung County.(2)Location quotient of fisheries are larger than 1.0.It means thatfisheriees are more localized(or concentrated)in Pingtung County than inTaiwan area as a whole.(3)Input coefficient of primary input sector of fishery is near 4 times ofthose of interindustry input sectors of fishery.(4)Index of power of dispersion(or standardized mean backward linkagelever)and the index of sensitivity of dispersion(or standardized mean forwardlinkage level)are lower than 1.0.(5)Evenness index of backward linkage(or evenness index of dependenceof interindustry input)of fishery is lower than those of other sectors.(6)Evenness index of forward linkage(or evenness index of distributionof interindustry output)of fishery is higher than those of other sectors.
