运用理论建模、计量检验、问卷调查及案例分析等方法，以正式规则的制定、实施及演进为主线，考察中国农村土地制度变迁的路径特征、决定条件及影响因素。（1）基于新制度经济学的制度变迁理论及行为经济学的前景理论等构建动态制度变迁模型，将强制性变迁与诱致性变迁纳入统一的分析框架，阐明中国农地制度结构中的正式规则、非正式约束及其实施特征的互动关系，以及制度变迁多重均衡的产生及选择。（2）拓展上述基本模型，重点考察中央正式规则的形成及调整，地方资源禀赋、地方政府行为、农户个体认知等对正式规则实施的影响，以及非正式约束上升为正式规则的条件。（3）在课题组前期研究基础上，进行大样本量的全国农地入户问卷调查，选择典型案例（如HRS改革、征地制度改革、“三块地”试点改革、“确权登记颁证”改革等）进行比较制度分析，对当前中国农地制度结构进行辨识与分析，最终为实现有效的产权正规化改革以及多元化的制度创新提出政策建议。

The objective of this project is to study the characteristics, decision environment, and determining factors of the rural land institutional changes in China. We utilize a wide array of research methods, such as theoretical model building, econometric analysis, surveys, and case studies. Our analysis focuses on the formation, implementation, and evolution of formal rules in order to accomplish the following tasks. (1) Based on Institutional Change Theory (ICT) of New Institutional Economics and Prospect Theory (PT) of Behavioral Economics, we develop a dynamic model of institutional change, unifying imposed institutional change and induced institutional change in a single framework. Our theoretical framework can explain the interactive relationships between formal rules, informal constraints and their enforcement characteristics, as well as the generation and selection of multiple equilibriums in the institutional changes. (2) We focus on the formation and adjustment of central formal rules to extend the above-mentioned theoretical framework. This is achieved by studying the influence of local resources endowment, local government behavior and individual farmer’s cognition on the implementation of formal rules, and the conditions by which informal constraints become formal rules. (3) A large sample of farmer household surveys will be carried out to study agricultural land institutions. Through typical cases (e.g., Household Responsibility System reform, land expropriation system reform, rural land market-oriented reform and rural land rights registration certification reform), we carry out comparative institutional analysis to identify the structure of Chinese rural land institutions, and to provide policy suggestions for effective reform of property rights regularization and differentiated innovation.
