中文摘要：

伴随城镇化建设的迅速推进，我国城市群和中心城市周边出现了大面积“新增空间”。由于地处城乡结合带，人口结构复杂、城乡文明交融，城市“新增空间”很容易成为“风险集中带”，大量风险矛盾向社区层面挤压。调研发现：生长于旧乡村的新城区，面临城镇新市民融城之难、治理主体权利互损之险、社区治理滞后之乱等风险。引入无缝隙政府和整体性治理的视角后分析得出：城市新增空间的社区风险是上游政府职责缺失问题在下游社区的集中爆发，社区治理面临“政府职责脱嵌”与“政府社会失联”的“双重缝隙”。为推进社区治理，应当构建“前期土地审批规划—中期质量监管—后期社区管理和自治”的无缝隙职责体系，强化政府社会之间的整体性治理。

英文摘要：

With the rapid process of the construction of urbanization, China’s city clusters and the peripheries of central cities have emerged large area of“newly-increased spaces”, which is easy to become“risk-focused areas”because they are located in urban-rural integration areas having complex population structure and integration of urban＆rural civilizations, so a lot of risks and contradictions put pressure on communities. The result of the survey shows that new urban area originated from the old countryside is faced with such risks：the difficulty of integrating new urban citizens with the urban;the crisis of mutual harm among the rights of all governance subjects;the mess of the hysteresis of community governance, etc. From the perspective of seamless government and holistic governance, it can be concluded that the community risk of the newly-increased space in the city is the concentrated bursts in the downstream community for the problem of the upstream government’s lack of duties and responsibilities, and the community governance is faced with“double vulnerabilities”, i.e.“the separation among governmental duties and responsibilities”and“the disconnection between government and society”. In order to promote community governance, the seamless system of duty and responsibility, i.e.“the land examination and approval in the earlier period—the quality supervision in the medium period—the community administration and self-government in the later period”, should be built, and the holistic governance between government and society should be also reinforced.
