5、职业道德在社会主义法制建设中有着极其重要的意义。检察官是我国的实施者与维护者，是国家意志与国家权力的主要践行者。检察官良好的法律职业道德对克服司法实践中的司法腐败，维护司法的公平、公正有积极的作用。是国家法律制度顺利实施的保障。它与公民、法人、国家机关工作人员的权利与义务、国家司法机关的清誉、国家政治生活、经济生活及其他社会生活的基本秩序密切相关。本文分为三个部分。第一部分是中国检察官法律职业道德的概括，这一部分为本文的研究指明方向；第二部分是中国检察官法律职业道德存在的合理性。只有研究了中国检察官法律职业道德存在的合理性，才能在此基础上提出培植中国检察官法律职业道德的措施；第三部分是培植中国
