欧共体法律一体化是对区域经济一体化的回应,是形成统一大市场的客观要求和必然结果,体现为成员国法律的协调和统一,其核心是共同法律意识(法律精神)的培植。文章分别从共同大市场的运作(尤其是商品、资本、人力和服务的跨国自由流通)和共同体制度建设两个方面论证了实现法律一体化的必要性及其意义。 The EU law integration is a response to the regional economic integration, an objective requirement and an inevitable result of the formation of a unified market, which is manifested in the coordination and unification of the laws of the member countries. Its core is the cultivation of common legal awareness (legal spirit). The article demonstrates the necessity and significance of the legal integration from two aspects: the operation of the common market (especially the cross-border free flow of goods, capital, manpower and services) and the construction of the community system.
