在城镇化迅速推进的过程中，社区作为城市的基本单位，集中反映了城镇化进程中的问题，社区建设也从单一的物质环境建设逐步走向完整社区建设。在现阶段我国社区建设中，建设的主体逐渐由单一的政府力量走向多元，开发商转型走向社区运营，居民社群不断成熟，社区组织力量开始出现，社区公众参与成为当前社区建设的一个重要议题。然而，不同的社区在规模、性质、发展阶段等上都呈现出明显的特殊性，其社区公众参与的实践也表现出不同的参与方式和成熟度。在这样的背景下，本文选择了三个带有典型特征的社区作为研究公众参与的案例，通过亲历式的社区考察和案例分析，紧扣社区自身特征，研究单个案例在社区公众参与全过程中的关键问题，分析不同社区在公众参与方面的表现及其内在逻辑，判断其参与实施机制的目前状态及包含的发展趋势。在此基础上，一方面，通过要素和维度的三社区对比，讨论影响社区公众参与表现的关键因素和关键事件，梳理三种典型的社区参与模式；另一方面，研究使用个案拓展的研究方法，在案例本身分析之上进一步深入讨论案例中蕴含的更具有社区普遍意义的结论，探讨当今社区建设中社区公众参与的局限性和不同的应对方式。

In these days, with the diversification of community governance, we break through traditional government-driven mode by degrees. Real estate developers try to turn themselves into community operators. Lots of changes follow: the communities grow to maturity; the organization forces emerge. In the meanwhile, the public participation becomes a topical issue. However, the scales, properties and developing stages of different communities are entirely distinct，the practice of public participation also happens in different ways.In the context, this paper selects three typical communities as the cases in the study of public participation. This study aimed to estimate the state and trend of participation mechanism with personal experience by analyzing the different characteristics of different projects in different communities and closely examining the critical issues in the cases.On the basis of the study, on the one hand, this paper summarizes the key factors and critical issues that affecting the public participation through the comparison of the three cases in the terms of factors and dimensions and generalizes three typical modes of community participation. On the other hand, this paper, aimed to carry out intensive research to discuss universal conclusions for all kinds of communities and explore the limitations of China’s public participation, is also expected to find out some specific measures to improve the performance of today’s community construction.
