Human beings’speech act has a goal driven.As a written discourse,contract has a very clear goal,which is the essence of it.The overall goal of“Contract Law”is to protect the legitimate rights and interests of the contracting parties,maintain social and economic order,and promote the socialist modernization construction.The key incentive for drafting a contract is the underlying goal,thus each term of the contract and every legal rule are derived from the goal.Liao Meizhen first proposed the theory of pragmatic goal-driven principles(GDP)in pragmatics.Under its guidance,contract discourse will be analyzed from four levels,namely,the national contract legal system,specific contracts of economic agents,contract disputes,and court hearing on contract dispute cases to clarify the rights and obligations of the parties,so as to achieve the economic goal of the contracts.
