背信损害上市公司利益罪是我国《刑法修正案（六）》新设立的背信类罪名之一，是专门维护上市公司利益而设置的，其目的是为了预防与惩治越来越多的经济犯罪，弥补现行刑法规范之不足。目前，背信损害上市公司利益罪还是个年轻的罪名，根据《公司法》对上市公司的规范，虽然针对上市公司高级管理人员损害公司利益的现象，我国《刑法》已经列举了几种典型的背信行为，但并不具体全面，也没有足够多的司法解释对这些犯罪行为作进一步规范。在司法实践中，因无法准确界定本罪与非罪、本罪与他罪之间的行为差别致使犯罪过程中的相关人员能够逃避刑法的制裁。最高人民检察院、公安部联合出台的《关于经济犯罪案件追诉标准的补充规定》只针对背信损害上市公司利益罪的追诉标准做出规定，并没有进一步界定具体犯罪行为。因此，正确把握背信损害上市公司利益罪的客观行为本质，明确其具体行为方式，深入了解其犯罪行为形态对于司法实践具有十分重要的意义。 本文除了前言与结论外，主要分为四部分。第一部分，介绍背信损害上市公司利益罪的犯罪行为本质。本文通过论述背信损害上市公司利益罪所保护的法益，研究其犯罪行为本质是违反忠实义务。在此基础上，通过比较各国公司法对忠实义务的表述与规范、忠实义务的重要性，以及我国公司法条文对忠实义务的规定，归纳总结了忠实义务的概念及其主要内容。第二部分，根据忠实义务的主要内容以及刑法分则条文的相关规定，结合具体案例，重点阐述了背信损害上市公司利益行为中的五种具体的犯罪行为，并提出其他几种法律法规并未规定但在某些情况下符合违背忠实义务本质的行为。第三部分，论述了本罪的停止形态和共犯形态下的行为。根据背信损害上市公司利益罪犯罪主体身份和职务不同，本文重点阐述了犯罪预备、犯罪未遂、犯罪中止时的行为认定等问题，以及在共犯形态下不同职务的行为人所触犯不同罪名的处理方式。最后一部分，根据上述各部分对本罪的客观行为的研究结果，指出本罪在立法上的不完善之处，并提出几点立法建议。
