Abstract: Defining the concept of value from the perspective of the conditional theory,it is thought that value is the result of the comprehensive effect of various conditions.The constitutive requirements of the conditional theory are one kind of existence form,two factors,three links,and two standards,and value is a dynamic process.Conditional theory of value not only enriches the theoretical content of the value theory,but also the three-dimensional thinking form of the research method extends the thinking space for the value study.
