In this paper, we introduce a grid accounting system for the grid economy, called PhoenixAccount. Focuses on the issue that the accounting in the grid economy need not only to motivate the resource contribution, but the control of the resource sharing, PhoenixAccount proposes 1) the close-looped use of virtual currency; 2) a new user payment model with the expression of the time-varying resource utility information and a resource price model which record the resource price in the form of price per time unit for each job; 3) the LOPI funding injection and resource charging model. In the performance experiments, the computational and economic efficiency of user jobs with PhoenixAccount are measured. The experiment results show that PhoenixAccount can support to take the funding as a form of user priority and motivate the resource contribution.
