It is an irresistible trend for industrial and commercial capital to flow to the countryside.Commercial capital into agriculture is a “double-edged sword”,which has made the community react strongly.At present the policy has only stipulated several principles,thus lacking rigidity and enforcement.We hold a strong belief that rental of commercial enterprises and usage of farmers’ “Family Contracted Land” should be adjusted and regulated through the sound land leasing legal system and the usage of strong legal weapons,and only in this way can we make the prospect of “there’re laws to abide by,there’re laws to comply with,law breakers must be dealt with” come true.This paper is based on the following points:analysis of the current policy and related comprehensive system,analysis and operation mechanism of legal norms of rental,the existing problems of law.Finally,six aspects of the legal countermeasures and suggestions have been put forward as follows to regulate the rental and usage of family contracted land on the part of the commercial enterprises:clearly define the qualifications of the agriculture-related entities and the conditions for the entry threshold,set up examination and approval system,improve the legal restraint mechanism of “Non-food” and “Non agriculture”,lift the mechanism of the leasing contract and reinforce special legislation.
