對于締約責任的性質，有四種學說，分別是侵權行為說，法律行為說，法律直接規定說和誠實信用說，筆者更傾向于誠實信用說，因為這是締約過失責任這一特殊階段要求的，當事人進行民事活動時必須具備誠實善良的內心狀態，其他學說都有些牽強。對于締約過失責任成立的場合，傳統的觀點是只承認合同不成立、無效或被撤銷的場合。筆者認為也應包括合同成立的場合，因為他同時也侵犯了非違約方的固有利益，雖然這部分利益不佔重點，但我們不能否認她們的存在，比如標的物有瑕疵，締約人違反保證等。Performance requirements and test methods for non - directional radio beacon
