中文摘要 |
本研究主要目的在於應用新近發展的等值臨界模型,對於國內常見之養殖魚類──吳郭魚在臺北、臺中兩地魚市場進行空間整合檢定,並與另兩種市場整合檢定模型──Engle & Granger(1987)二階段共整合模型和Johansen(1988)共整合模型比較,希望藉此三種不同方法之比較,以了解吳郭魚是否在臺北、臺中兩地間存在資訊、物品自由流通,進而符合單一價格法則,達成空間市場整合,並推論市場間是否存有運銷障礙。根據本研究實證結果,吳郭魚於臺北、臺中魚市場間或市場內尚未發現有重大運銷障礙。比較共整合模型及等值臨界模型時可發現,前者在推論市場整合時並未考慮轉運成本,使得市場整合檢定結果有高估現象;而等值臨界模型則利用常態分配求取價差等於、小於及大於轉運成本等三種市場整合情況之機率值,應更能說明兩地市場整合情況機率,此與共整合模型檢定拒絕或接受僅兩種兩極化的結果相比較,其對市場間整合程度應可提供更多的資訊。
The purpose of this article is to apply the parity bounds model testing aquaculture fish market integration in Taipei and Taichung. Using this result compares with Engle & Granger (1987) causality and Johansen (1988) cointegration so that we could understand the situation between of these two markets. If there are any restrictions between them. As a consequence of this empinical study, it seems market intergration. Compared with the parity bounds model, the cointegration approach would over-elvaluated the result of testing market integration. The parity bounds model proposed more information concerning market integration. |
