In recent years,China's service industry has flourished,and service contract disputes have also increased accordingly.Therefore,it is necessary to clarify the current legal provisions relat-ed to service contracts and provide legal support for dispute resolution.In terms of the legislative model of service contracts,the current typology model at different abstract levels is more appropriate compared to general provisions for service contracts.The reason is that general provisions tend to o-verlook the specificity of various contracts and require judges to undertake the work of concretization and typology during the judgment process,which would undermine legal stability.When applying le-gal provisions related to service contracts,typological thinking serves two purposes:guiding the ap-plication of law and finding points of comparison in similarity judgments by analogy.Typological thinking has different emphases in ius dispositivum and ius cogens when used to guide the application of the law.When applying ius dispositivum,typological thinking can fill contractual gaps;while when applying ius cogens,it can help to realize corresponding legal values.
