The Civil Code of PRC has not set up an independent part of general provisions of law of obligation.The absence of any part of general provisions of law of obligation within a Civil Code makes it all the more urgent for the inclusion of general theory into the science of civil law.The identification of the general provisions of law of obligation in the Civil Code of PRC is of great use in at least four ways:first,it aids the judicial bodies in their formulation of an accurate and comprehensive basis for judgment;second,it helps the legislative branch find the right direction to improve the obligation law system in the future;third,it provides more options in the mode of private behavior;last but not least,it lays a good foundation for the teaching and research of civil law.In order to identify the general provisions of law of obligation,we should truly grasp the essence of the obligatory relationship and the legislative technique of common factor method.In a substantial sense,the Civil Code of PRC includes such general provisions of law of obligation as their subjects,objects,effects,preservation,assignment,and extinction.In order to provide guidance on their correct application,the interpretation of these provisions,especially their connotations,should be strengthened.
