所謂「預測」，是建立在對特定事物認識的基礎上所做出的預估，而預測的準確與否關鍵即在於預測者對資訊的掌握程度。長久以來，由於未來一直是人類亟欲征服與掌握的目標，因此預測也成為一普遍存在的行徑。有別傳統預測方法的諸多限制，「預測市場」藉由網路參與者主動參與價格為訊息加總等特色，可以更全面的涵蓋不同來源的資訊並進一步轉換為一個量化的指標，以達到更準確的預測。本研究藉由「未來事件交易所」中兩岸相關協議的個案分析，發現市場在預測的過程當中，價格除了藉由公開資訊的反映出來以外，其中亦包含了大量私人資訊的反映，兩者反映所有資訊次數的比例大致維持著4：6的關係，而這結果也代表了在兩岸議題當中資訊並未大幅被揭露，欲準確預測事件的結果仍須多方仰賴私人資訊的貢獻。此外，根據個案分析的結果，本研究也發現兩岸協議確實適用於兩岸議題的應用。 / Prediction is an anticipation based on specific events. The key point of correct prediction depends on the level controlled by predictors. For a long time, future has been a target for human to control and overcome. Thus, prediction becomes a way to explore future events. “Prediction markets” is different from traditional way. It gets rid of many restrictions. It transfers all diverse information from participators into a quantification index to predict more correctly. This research analyzed by Cross-Strait Agreements on Xfuture.com finds that market price is reflected by not only public information but also private information. The ratio of public information to private information is 4 to 6. The result indicates that information is not disclosed completely in Cross-Strait Agreements. By solving this problem, we should use private information to predict more precisely. Furthermore, Cross-Strait Agreements certainly applies to Cross-Strait Affairs according to this paper.
