In the view of Three Rights Division,the orderly circulation of land management right and the effective withdrawal of right to land contractual management are two different ways of alleviating the contradiction between rural people and land,and promoting the moderate operation of farmland.Considering the immaturity and limited function of the transfer mechanism of land management right,it’s essential to construct the corresponding exit mechanism.Since the land contract right is a compound right featured by property,identity and social security function,its exit mechanism should be prudently constructed.In legislative style,it’s obligatory to adhere to the statutory principle of quitting the land contract right and clarify the binary mode of “principle prohibition and exception permission” for regain of contracted land,which prohibits the parties’ free behavior by agreement.In terms of legislation contents,it is necessary to improve the types and procedures of voluntary return and regain according to laws.Firstly,returning the contracted land is legally exposited as the contractor abandoning or transferring its right.More precisely,the abandoning is based on the premise of the contractor losing its identity of collective member and the transferring is restrained within the contract period.These two ways are supposed to be the major ways of return.Secondly,there are two legal interpretations for “regain according to law”, identity regain and non-identity regain.More precisely,reasons for identity regain include household registration transfer and death of the contractor's family; reasons for non-identity regain include the contracted land left unused,destroyed or expropriated.To guarantee the pattern of “big stability and small adjustment” in land contractual relationship,it is of vital importance to build legal system and procedures of quitting the contracted land.
