宋代是古代中国土地私有制发展极为充分的一个时期,在“田制不立”、“不抑兼并”的背景下,官田私田化这一政策具有显著特点及研究价值。通过梳理官田私田化的历史概况,建立有限理性的非对称鹰鸽进化博弈模型,并对这一政策的实施及其施政动力做了具体分析,给出了对此政策的评价;并且,继续依循这一问题的方向,提出了当今中国农地产权残缺的思考,以古为今用的理念给出了相应的政策建议。 The Song Dynasty was a period in which the development of private ownership of land in ancient China was extremely adequate. Under the background of “lack of establishment of a system of land” and “no restraint of mergers and acquisitions”, the policy of private ownership of officials in fields is characterized by its distinctive features and research value. By combing the history of Kintetsu’s private ownership, this paper establishes a bounded rationality asymmetric Eagle pigeon evolutionary game model, and makes a concrete analysis of the implementation of this policy and its driving force, and gives the evaluation of this policy. Continue to follow the direction of this issue and put forward the thinking on the incompleteness of farmland property rights in China today, and give corresponding policy suggestions based on the concept of ancient and modern use.
