This article analyzes how the choice of governance model affects income ratio of between the capital and labor groups and future development in a society. Governance models might be divided into anarchy, regulatory government, centralized government and elected government. The income ratios of between the capital and labor groups and social sustainable developments in four governance models are shown by a basic model. Both anarchy and regulatory government would be unsustainable early or late, centralized government would be uncertain in sustainable development, while elected government would be durative because of equality. Therefore, a governance model should be designed as elected government or centralized government in a society, and if centralized government is chosen, it is necessary to keep it sustainable for us.
