中文摘要：

单位制是计划经济时期中国实现现代化而在城市构建的基本工具，其研究是理解历史、解读转型的重要视角，其积极因素将构成规划城市未来的重要理念。单位制研究已有30年的历史，涉及社会学、地理学、规划学等多个学科。总体而言，单位制度研究比较成熟，单位空间和社会研究在研究成果方面相对不足。单位制度起源研究有路径依赖、资源约束等视角，但确切性还不充分。单位制度形成与发展的阶段划分还未形成统一的看法。转型以来，不同类型的单位之间分化明显，不同类型的单位均有研究，但整体的判断还不明确。空间研究中，物质空间研究成果较多，但解释不足，行为空间和社会空间相对缺乏。从单位制社区向城市社区的转型得以广泛关注，但转型的路径、阶段、机理及其影响、优化策略等还有待深入探讨。

英文摘要：

Danwei system is the basic tool constructed in the period of planned economy to achieve Chinese modernity, whose research is an important perspective to understand history and interpret the transition, and whose positive factors will be part of those important urban planning ideas. Danwei system research has experienced a his- tory of more than 30 years, concerning sociology, geography, planning, etc. In general, the institutional research has more achievements, and the researches of Danwei space and Danwei society are still in need. The Danwei sys- tem origin research has perspectives of path dependence and resource constraint, but without enough tangibility. A uniform opinion of the stages of Danwei system formation and development has not come into being. Since the tran- sition, different Danweis have experienced different transitional paths with different effects. Though the existed re- search has covered different Danweis, a general judgment is not clear enough. As for spatial research, material re- search has more achievements but still needs more interpretation. Behavior and social space research is not enough relatively. The transition from Danwei community to urban community has attracted much attention, but the transi- tional paths, stages, mechanism, effects and optimizing strategies still need more study.
