In a general sense, openness pertains to the economic relations between nations. From a Chinese perspective, opening up involves the economic relationship between China and the rest of the world. From a practical logic perspective, China’s opening up has evolved from initially passive participation in the global economic cycle to progressively taking the initiative in reshaping global economic relations. Theoretically, the division of labor and exchange constitute the foundational logic of an open economic system. However, capitalist economic globalization, which regulates global resource allocation through the law of international value, ultimately leads to a polarized global development landscape. An unjust international monetary system has fostered an economic relation pattern characterized by “control-plunder”. The essence of high-level opening up lies in restructuring China’s economic relations with the world, with the goal of achieving dynamic equilibrium in economic fl ows between China and other countries or economies. The mechanism for realizing this involves the global allocation of resources through internationally combined labor to achieve internationally combined productivity.
