中文摘要 | 本文引用Adelaja(1991)的分解性成分法分析有色雞與白肉雞對價格變動 所作的長、短期反應,及評估關稅化對養雞業者所得或產值之影響。方法以 Koyck反應函數式及似乎無相關迴歸分析法來推估肉雞供給反應式。實証結果顯 示白肉雞與有色雞在短期均缺乏彈性,且白肉雞的價格彈性小於有色雞的價格彈 性。但在長期則白肉雞與有色雞均富於價格彈性,且白肉雞的彈性卻比有色雞彈 性大,可能原因為:(1)資本密集;(2)專業程度;(3)資金融通能力;(4)進出障礙大 小。對於自由化貿易的價格變動白肉雞與有色雞有不同的價值反應,白肉雞是先 增後減,而有色雞則先減後增。 |
英文摘要 | By applying Adelaja's method to decompose the broiler supply elasticity into the elasticities of the broiler and the colorful broiler in Taiwan. The impacts of price changes on the short-run/long-run outputs or revenues responsiveness of the colorful broilers and the broilers are examined, while the effects of tariff on their income or revenue are also evaluated. The Koyck response function and seemingly unrelated regression method are used to estimate the broiler model. The results are shown that the elasticities of the broiler and the colorful broiler are inelastic in the short-run, and the broiler is less price responsive. But in the long-run their elasticities are elastic, and the broiler is much more price responsive. The reason can arise from differences in (a) degrees of capital intensity, (b)degrees of specialization, (c)financial ability, and (d)magnitudes of barriers to entry and exit. The effects of free trade on the broilers and the colorful broilers are different, the broiler is shown to increase price responsive first and then decrease with time, but the corlorful broiler is decrease first and then increase with time. |
