The advancement of information and communication technology and the reduction of trade costs have promoted the formation of global value chains,while the development of global value chains has promoted the innovation of international trade accounting methods and spawned a new interdis-ciplinary research field.Foreign scholars have not only conducted in-depth research on the conceptual evolution of global value chains,but also conduc-ted detailed analysis on their relationship with global commodity chains,industrial chains,and supply chains.The latest literature focuses on"account-ing methods for global value chains","driving forces behind changes in the division of labor in global value chains",and"the economic impact of global value chains on developing countries",conducting extensive and in-depth economic research.The research finds that innovation,institutional policies,digital economy,COVID-19 epidemic and new protectionism are all important driving factors for the change of the division of labor pattern in the global value chain;at the same time,the development of global value chains will also have a counterproductive effect on innovation,the develop-ment of the digital economy,and institutional policies.Although global value chains can promote the economic growth of developing countries,their im-pact on industrial upgrading remains unclear,and they also have negative effects such as inhibiting corporate independent innovation,aggravating labor exploitation,and intensifying competition.This article systematically reviews and analyzes the classic literature and the latest economic research on global value chains,which has certain positive significance for subsequent research and policy formulation.
