在经济学的视野下 ,博弈工具论证了代表法律制度强制力的政府的出现降低了界定和保护产权的费用 ,从而使产权安排得到普遍的尊重 ,但政府并不是合约交易的前提 ,而是合约交易规模经济的结果。政府的出现也是一个交易活动的历史演变过程。博弈模型的继续扩展和现实运用 ,有助于对政府的类型及政府机会主义进行剖析 ,从而推导出契约论宪法观及法治的内核及意义。 From the perspective of economics, the game tools demonstrate that the emergence of a government that represents the force of the legal system reduces the costs of defining and protecting property rights, so that property rights arrangements are universally respected. However, the government is not a premise of contractual transactions but a contract Deal economies of scale. The emergence of government is also the historical evolution of a trading activity. The continuous expansion and practical application of the game model help to analyze the types of government and opportunism of government and derive the core and significance of the contractual conception of constitution and the rule of law.
