Compared with ancient contract laws, the expansion of the effect of contract is one of important aspects in the changes of modern contractual relations ,and it is fully reflected in the rules of contract laws. Due to the expansion of the responsibilities effect of contract, the nature of the subjects, the contents and the also change. As a result ,the modern rules are different from those based on traditional contract laws with contractual relativity.The essence of contractual relativity is the relativity of the effect of contract. This kind of relativity is expressed by certain facial elements which are the relativity of subjects, the relativity of contents and that of responsibilities Just because of this strict relativity, the civil rules of debt have its own characteristics. The Roman Laws established the contractual relativity leading to the split of creditor's rights and owner's rights which followed by the common law and the Civil Law systems .However, the existed exceptions with its emergence .With the development of contract laws, these rules are becoming more and more obvious. Though the evolving orbit in his tory reflected the national inheritance and creativity, they all originated from the obedience and breakthrough in contractual relativity and demonstrated the value of the ancient rules in modern civil laws.The expansion of the effect of contracts can not be cut off from the development of social relations and theoretical supports. By the analyses of the causes of the expansion of contract and the induction and comparison of the subjects, the contents and the responsibilities of the contracts, we may see that the external expansion of the effect of contract is a.very common phenomenon, Secondly ,we may see the inevitability of the formation of the theories and the rules about the external expansion of the effect of contract finally demonstrate in modern contract laws, the rules of the expansion of the effect of contract has rooted in modern contract legal systems and formed a of contract laws.With the issuance of our unique Contract Law of P. R.C, the principal of contractual relativity come back to the rational orbit in both judicial and legislative aspects. The legalism of the exceptional rules avoided the intimidation of responsibility with the unlimited expansion of the effect of contract.
