摘　　要：针对网格资源这一交易市场,提出了一种改进的网格计算经济模型。深入研究了资源提供者和资源消费者在进行交易时的价格策略,涉及到类似现实生活中交易时的供求关系以及资源信誉度对价格的影响。提出了资源调度双方的信誉值算法,并以该算法作为决策记账和支付策略的依据。通过仿真模拟整个模型体系及其策略,与商品市场经济模型相比,模型在系统吞吐量上有所提高,受供求关系的影响较小。Based on the trading market of the resources in grid, an improved grid computing economic model was proposed. The price strategy which was used as a rule during the trading course between the provider （GRP） and the consumer （GRC） of the grid resource was profoundly researched. It was defined by the condition of supply and demand of the grid resources and the influences of the grid resource credit. A formula was proposed to calculate the credit value of the GRP and the GRC, which helps to decide the strategies for accounting and charging. The result of the simulation of the grid computing economic model shows that the model has a higher number in trading, which has little influence on the demand and supply of the grid resources compared to the commodity market computing model.
