Existing theories of international relations cannot explain major international issues such as how Chinas rise has changed the world order. The Chinese studies of world politics has provided substantial inspiration, so it is urgent to build a discipline of world politics. The research finds that the world market, which contains technology and capital, and the political thoughts generated by the world market, have connected isolated countries or regions and formed an interactive institutionalized network. Therefore, the units of analysis of world politics should be the world market and political thoughts, which are also the driving force of world political changes. The logic of the evolution of world politics is that social history has led to competitive and antagonistic resource allocation, which in turn has given birth to the world market, while the dominant and the dominated in the world market construct their own political ideas and thoughts, which has changed the political systems and brought about changes in the relations between great powers and in the world order. World politics is a contradictory body, and confrontation has been a constant feature of the history of world politics. Nevertheless, China, a country brought forth by the political history, has entered into the world arena, and its approach to development and its worldview will certainly contribute to the formation of a new form of human civilization.
