Abstract: With the globalization of the world economy, the industrial development is gradually extended from the domestic realm into the world arena, thus the global value chain comes into being, it is the outcome that the developed countries reorganize and consolidate the global essential elements. However, behind the global value chain there is the global technology chain where the transnational corporation groups from the developed countries integrate and utilize the intellectual resources in the world, but they grip the high end of the technology chain, keep the industrial kernel technology in their palms, update the industrial technology standards, and forge industries into barriers continuously. The global technology chain presents the chained distribution in both horizontal and vertical directions. The essence of the industry update is the updating technologies. Therefore, the analysis of the distribution of the technology chain and the path of the technology updating contributes to the successful merging of the developing nations into the global technology chain, promoting their own industrial levels, narrowing the industrial technology gap, and enhancing the industrial competitiveness.

Key words: global value chain, global technology chain, evolvement, update
