The interdependence of economics among countries has been distinctly enhanced due to the end of the Cold War and the intensification of globalization. In terms of its content and form, geo-politics has shifted from a "high political area", which focuses on safety, to a "low political area", which emphasizes economics, making geo-economics the focus of the researches. Using tools including Exploratory Spatial Data Analysis (ESDA), Fragmentation Index and Revealed Comparative Advantage Index, this paper revealed China's evolutionary characteristics of geo-economic connections at the global scale, and explored its internal mechanism by grey relational analysis. The results show: (1) China's geo-economic connections have undergone 4 periods of "Inoculating - Sprouting - Rising - Flourishing", which were significantly correlated to economic development and the industrial restructuring. (2) Labor-intensive industry is currently dominant in China, but capital-intensive and technology-intensive industries are gradually developing, and the disadvantages of primary goods is prominent. (3) China's economic power is heterogeneous across space. The geo-economic connections could be identified as global powers' agglomeration and geographical proximity, but it became homogeneous through time and the diameter of economic power has continuously expanded. China has not only maintained stable geo-economic connections with developed countries like the United States of America, Japan and some European countries, but also strengthened connections with developing countries in Africa and South America. (4) Capital, technology and labor endowments are the main internal driving forces behind the spatial-temporal evolution of China's geo-economic connections, among which capital endowment is the key driving force, technology endowment is the important impetus and labor endowment is the fundamental advantage.

This paper tried to understand the global geopolitical economic base from the view of Krugman geographical natures. By collecting the added value in the financial and manufacture sectors of the world's major 21 countries or regions from 2000 to 2012, the authors applied a location quotient model to analyze quantitatively the and concentration status of the world's major countries in both sectors, compared with the situation of resources output in countries and regions. The paper obtained a clustering catalogue list, i.e. "Three Worlds" in globalization era: financial-leading countries (areas) such as USA, UK, Switzerland, Singapore and Hong Kong (China), manufacturing-leading countries (areas) such as Thailand, China, South Korea, Germany, Japan, Vietnam and Taiwan (China), and resource development leading countries (areas) such as Canada, Russia, Indonesia, Malaysia, Australia and Mexico. Some countries like India and France, surfaced in equivalent development and might be defined as transitional countries. This classification of economic division may be a guidance for the standing points in each country in geopolitical and geopolinomical sense.
