Abstract: The vocational education policy in China since 1978 has undergone three stages:adjustment of secondary education structure(1978-1995), exploration of vocational education (1996-2010), and establishment of modern vocational education system (2010). Using different orientation analysis models,the authors argue that the evolution logic in the development of vocational education policy can be summarized as follows:the dynamic mechanism by means of management system adjustment, the policy value orientation of vocational education goals, the process assurance of the implementation of vocational education policy based on specification of people and property, the cultural rules of vocational education policy discourse dominated by economic discourse. Finally, the paper discusses the future trend of vocational education policy. First, the formation mechanism should be changed from "ambiguity of power and duties" to "unified coordination". Second, the value orientation should be changed from "single utility" to "multi orientation". Third, the policy of vocational education should be changed from "lack of supervision"to"strict supervision". Fourth, the policy discourse should be changed from "government-oriented" to "public participation".

Key words: vocational education policy, dynamic mechanism, value orientation, process support, culture rules
