中文摘要：

土地产权制度改革在新时期受到了经济社会各方面新的挑战,原有的产权改革理论已经无法适应现阶段土地利用和管理实践的需要。如何在原有产权改革的基础上,将土地产权的政治性质、社会组织性质和法律性质完整地体现到现阶段土地产权制度改革创新的内涵中,并为中国土地产权改革提供路径,是理论研究的主要任务。而这需要将经济学和社会学的理论结合在一起来分析相关问题。Williamson提出的社会科学分析的四层次框架提供了一个新的能够联系产权与资源配置、社会学和经济学的分析逻辑。通过该逻辑能够较全面地掌握中国土地产权制度的性质并作出评价,同时也为现阶段土地产权改革的可能路径提供理论基础,这些都为中国新一轮的土地产权制度改革提供了科学依据。

英文摘要：

The institutional reform of land property rights is confronted with various challenges from all aspects of the economic and social lives in the current stage.The original property reform theory does not agree with the current practical requirement of land use and management.How to fully reflect the political,social,organizational and juristic nature of land property right in the newly-formed concepts of land property reform and its institutional innovation,and further provide a trajectory for future reforms in China,are the main purposes of our theoretical research.It needs to combine together the theories of economics and sociology to analyze related issues.The four-level-social-analysis framework proposed by Williamson provides a good logic to link property right with resource allocation,sociology with economics.Through such a logic,a comprehensive analysis on the nature and the assessment of Chinese land property can be achieved,which can further provide a theoretical basis for the trajectory choice of the current land property reform.The analysis offers scientific references for the new-round of land property reform in China.
