《罗马条约》是欧洲一体化的法律基础。在欧洲一体化的过程中,法律对欧盟多样性联合起着重要作用,主要是提供制度框架,确立制度标准;直接促成共同市场的形成,促进了欧盟内部的自由贸易;欧盟法律促进了“欧洲认同”;利益平衡与定纷止争。同时,欧盟法的超国家性质带来了有待解决的新法治课题。 The “Treaty of Rome” is the legal basis for European integration. In the process of European integration, the law plays an important role in the EU diversity alliance, mainly providing the institutional framework and establishing the system standard; directly leading to the formation of a common market and promoting free trade within the EU; and the EU law has promoted the “ European identity ”; balance of interests and disputes will be determined. At the same time, the supernational nature of the EU law has brought about a new subject of rule of law to be solved.
