研究发现，当前北京高层老旧小区的老化问题体现在物质空间使用和制度管理维护两个方面，和多层老旧小区相比，这两方面既有共性，也有因人口密度、高层建筑空间特征、产权及社会管理形式不同等原因造成的较大差异。首先，在物质空间使用方面，和多层老旧小区聚焦于电梯不同，高层老旧小区在空间组织、节能改造、公共环境品质等方面均存在较大老化落差，并且，不同年代建设的高层老旧小区彼此之间的需求差异较大，需要有针对性地展开深入调查和研究，进而提出改造重点。其次，在制度管理方面，和多层老旧小区相比，高层老旧小区普遍规模更大、人口密度和总量更高、社区人口组成更加复杂，因此在物业管理、居委会/业委会/物管会组织、以及居民满意度/归属感/参与意愿上存在更大的困难和挑战，所需维护和改造资金缺口和需求也更大。目前已经开展的部分社会资本引入和社区治理等“微利可持续”做出较好尝试和示范，但要进行大面积推广仍需要在制度体制上进行更多研究探索。
Research has shown that the aging problem of Beijing‘s old high-rise residential complexes is manifested in two aspects: material space use and institutional management and maintenance. Compared with multi-storey old residential complexes, these two aspects have both commonalities and substantial differences due to factors such as population density, high-rise building space characteristics, property rights, and social management forms. Firstly, in terms of material space use, compared with multi-storey old residential complexes which focus on elevators, old high-rise residential complexes have greater aging gaps in terms of space organization, energy-saving transformation, and public environmental quality. Furthermore, due to the differences in needs of high-rise residential complexes built in different eras, targeted investigations and research need to be conducted to propose transformation priorities. Secondly, in terms of institutional management, compared with multi-storey old residential complexes, old high-rise residential complexes generally have a larger scale, higher population density and volume, and more complex community population composition, posing greater difficulties and challenges in terms of property management, organization of neighborhood committees/industry committees/property management committees, as well as residents‘ satisfaction/sense of belonging/willingness to participate. The gap and needs in terms of maintenance and transformation funds are also greater. Some social capital introduction and community governance initiatives that seek to achieve "micro-profitability and sustainability" have been undertaken with some positive results and examples, but more research and exploration is needed to promote their wider implementation in the system and framework.
