The connotation of power undergone an evolution from the general"ability"and"influence"to the strict"coercive will"and"unequal relationship".There are some reasons why the concept of"power"in Western jurispru-dence has long been attached to"right".Immanuel Kant,Jeremy Bentham,and Austin John,on the basis of inheriting Roman law's view of power as the dominant force,recognized for the first time that"power"is different from"right".Salmond and Hohfeld's detailed analysis of the concept of legal power focused on distinguishing between"power"and"right"in private law,which echoed Locke and Montesquieu,who emphasized the power of public law.Subsequently,Friedman et al.deepened and linked the theories of private law power and public law power to make the concept of"pow-er"more legal and holistic.The concept of"power"in China,Japan and other Eastern countries is different,but it has not yet gained the status of an independent category in the field of jurisprudence,whether in the West or the East.
