基于“结构-行动”分析框架的宅基地退出机制研究——以宁波市为例

基于“结构-行动”分析框架和面板数据模型，以宁波市为例，对宅基地退出机制进行了实证分析。结果显示：（1）2000—2015年，宁波市宅基地规模和退出潜力持续增长；（2）人口和劳动力转移、耕地保护是驱动宅基地退出的主要机制。虽然农户个人建房受到一定限制，但是农户收入的增长推动了宅基地规模持续扩张；（3）宅基地退出机制缺失主要表现为正式制度的不完善和治理制度的低效。研究表明：符合土地市场机制的土地产权制度设计、多主体行动协同的退出模式构建和空间规划引导是宅基地退出机制完善的努力方向。

Homestead Exit Mechanism Based on "Structure-action" Analysis Framework:A Case Study of Ningbo City

Based on "structure-action" analysis framework,dpanel data model,take Ningbo City as an example,this paper studies the homestead exit mechanism to make an empirical.The results show that:(1) from 2000 to 2015,the scale and exit potential of Ningbo homestead increased continuously,and the evolution process of exit potential was characterized by strong negative decoupling model；(2) the transfer of population and labor force and the protection of cultivated land are the main mechanisms to drive the exit of homestead.Although farmers' personal housing construction is limited,the growth of farmers' income has promoted the continuous expansion of homestead scale；(3) the lack of homestead exit mechanism is mainly manifested in the imperfection of the formal system and the inefficiency of the governance system.The research shows that:the design of land property right system in accordance with the land market mechanism,the construction of multi-agent coordinated exit mode and the guidance of spatial planning are the direction to perfect the homestead exit mechanism.
