论所有权保留制度中的买受人期待权

在所有权保留买卖制度中，期待权为民法特别是合同法理论十分关注的问题，国外研究相对较多，并且已经形成了多种学说。尽管我国《合同法》第134条规定了所有权保留制度，但对买受人的期待权未明确规定，理论研究也不够深入。对所有权保留买卖中买受人期待权的性质、效力、转让以及保护等问题进行阐释并作进一步探讨，有利于更好地解决司法实践中不断出现的纠纷。

The Expectant Right of the Buyer in the Retention of Title Sale

In system of Retention of Title, expectant right is the key point of the Civil Law, especially in Contract Law theory. At present, foreign research is relatively rich and has formed a variety of doctrines. Although the 134th article of the Contract Law of China stipulates the system of Ownership Retention, but the buyer''s expectant right has not been stipulated. The theoretical research about it is not deep enough. It is helpful to solve the disputes in judicial practice to do further studies on nature, effect, transfer and protection of expectant right in Retention of Title.
