Abstract: Geo-economics was advanced by researchers of Europe and America in 1990s, and then it was speeded over the academics. But there were some different views towards its concept and nature, which has affected the development of the theory. This paper discriminate the nature and connotation of features from the practice of Europe and America of geo-economics background, theoretical origin, the development of schools and so on by a view of embryology. The main research conclusions as follows :(1) Geo-economics of Europe and America has profound theoretic origin. The re-occurrence of geo-economical cooperation around the world is one vital resource and theoretical background of the birth of Geo-economics. Meanwhile, the expansion of several other similar or related economic theories brings about its birth academically and geo-politics is its direct academic resource. (2)As space spread of the geo-economic theory, there are formed a multicentre centers of distinctive theory school such as the USA, Italy and Russia. The interaction among theories, views, and academic schools of different sub-subjects has made Geo-economics rather sophisticated; (3) Although geo-economics has formed its own unique theoretical characteristics different from geo-politics, it is still at the very early stage of its development with obscure research border, yet-to-be-build theoretical foundation and imperfect theoretical system.

摘要： 20世纪90年代初欧美地缘经济学一经诞生，就备受关注、讨论及推崇，但在其性质及内涵的认识上则出现了诸多分歧，已影响到学科理论及实践的进一步发展。从地缘经济理论发生学角度，对欧美地缘经济学的实践背景、理论缘起、发展流派等进行回顾与梳理，以辨析其性质及内涵特征。主要研究结论：（1）欧美地缘经济学具有深刻而丰富的理论渊源。世界范围内地缘经济合作实践二度兴起，成为理论内涵的重要来源及宏观背景。多个相关或相近学科的研究成果，为其提供了理论准备，地缘政治学则是其直接理论来源；（2）随着地缘经济学理论的地域扩散，形成了以美国、意大利和俄罗斯为中心的多个各具特色的理论学派。不同学科及其分支理论、观点与流派之间相互借鉴、交叉与融合，使其变得极为庞博复杂；（3）地缘经济学已形成有别于地缘政治学的理论内涵及特征，不过总体上处于学科理论的初创阶段，其研究边界尚不清晰、核心理论有待建立、学科体系有待完善。
