Abstract: The power of cyberspace is a tool with which the social actors take advantage of information technology and information resources to control and dominate others. Relying on technology and discourse as the dual support， the Internet has reshaped the settings of human production and living. It links the world as a field between the global and local conflicts， where power flows among different countries or individuals. With the shaping of information technology， the power of cyberspace has presented its operating characteristics with the unity of decentralization and centralization， being productive rather than repressive. The developing countries should not only use the new opportunity to develop information technology and actively participate in the global Internet management， but also construct their own ideological system so as to fight against the erosion of global discourse into national culture power.

Key words: cyberspace, technology, power, discourse power
