Abstract: A resource allocation method based on inframarginal analysis in distributed computing environment is presented to describe the resource allocation framework based on its comparative advantage, which maximizes the system utility by the global balance resulting from corner analysis, with the IRD(inframarginal-analysis-based resource allocation model for distributed computing) model for free transaction and IRDL(IRD limited) model for transaction limitation both developed. Differentiating from the neoclassical economic theory which studies how to improve the resource utilization ratio, the new classical economic theory studies how to decrease the resource scarcity through the division of labor so as to achieve the Pareto Optimality entirely by regulating the network dynamically. Simulation results showed that both the models developed are effective and rational though the IRD model is more suitable for the distributed computing environment.
