| Abstract | This article study the internal relationship between network and information, found the characteristics of the network information gathering and information pool, put forward the concept of time duplicate, build duplicate economic model, reveal the principles which the value of the network information pool and social welfare of the time duplicate through the analysis of the general equilibrium between time reproduction and monetary income, and demonstrate network synergies effect and endogenously scale economy. In this paper, on characteristics of network information pool (no-wear, no-crowded and no-dimension etc), and the concept of time duplicate (network time duplicate to create time and its degree of freedom), network synergies effect and endogenously scale economy, and so on, whose results can give the fountain found for studies about the network and information, the network economy and network economics development and research. The duplicate economic model which is set up in this article provides a basic analysis method for those. |
