本研究從產能成本與消費者價值的觀點出發，經由服務可用性與網路服務品質，聚焦在集權式與分散式的無線網路服務商業模型。我們發現集權式商業模型的結果特色與過去在機制研究上的結果一致；但是，分散式商業模型的結果特色與過去研究的結果相異。這個現象是由於在分散式商業模型的服務利益水準與貢獻者數目正相關。除此之外，當提高每個存取點的服務品質要求時，我們建議採取集權式的服務供應商能考慮將網路流量統一處理以降低產能成本；類似地，在分散式的商業模型底下，若採取較高的服務品質要求時，鼓勵所有訂戶作為存取熱點的策略不一定是最好的策略。

This study concentrates on the operation of mechanism design in centralized and decentralized business models for wireless services under the aspects of capacity cost and consumer valuation in terms of service availability and Quality of Service (QoS). We find that the features of the results in the centralized business model are consistent with those in prior studies in the mechanism design; however, the features of the results in the decentralized business model are contrary to those in prior studies. This phenomenon is caused by the fact that the level of service benefit in the decentralized business model is positively associated with the number of contributors. In addition, when imposing high QoS requirements on each access point, we suggest that a service provider adopting the centralized business model can consider aggregating data traffic to reduce capacity cost; likewise, encouraging all subscribers to serve as access points cannot be an optimal strategy for service providers adopting the decentralized business model with high QoS requirements.
