英文摘要：

The regulations governing stock repurchase in Japan have experienced three phases in their history, that is, from prohibition to exceptional permission to permission in principle, while the relevant legislation in China at present finds itself at the exceptional permission phase. Drawing on the successful experience of Japan, it is advisable for China to further relax the restraints and, at the same time, prevent malpractices that may result from doing so, and set up a complete system of regulations which should include the examination of qualifications, disclosures, manners and the sources of funds.
