城市萎缩已成为后社会主义城市的一个共同途径（不仅如此），这对传统的增长导向的空间规划提出了新的挑战。而在后社会主义地区，由于计划文化薄弱，发展不协调，这种情况更为严重。奥斯特拉瓦市的情况说明，在已经支离破碎的城市结构中，基础设施运营和维护效率低下的问题是如何由于城市面积的不断扩大（通过低密度的土地使用）以及人口规模的不断减少（由于向外移民率高）而加剧的。然而，城市内部的收缩在空间上是有区别的。矛盾的是，在财政要求最低的土地使用中，人口下降最严重，而在公共管理最昂贵的土地使用中，人口增长最严重。由于人口和城市结构的发展具有很强的惯性，这种土地利用的发展对城市未来的可持续性构成了巨大的挑战。本文的主要目的是探讨与城市萎缩有关的人口密度模式变化与公共财政可持续性之间的关系。
Urban shrinkage has become a common pathway (not only) in post-socialist cities, which represents new challenges for traditionally growth-oriented spatial planning. Though in the post-socialist area, the situation is even worse due to prevailing weak planning culture and resulting uncoordinated development. The case of the city of Ostrava illustrates how the problem of (in)efficient infrastructure operation, and maintenance, in already fragmented urban structure is exacerbated by the growing size of urban area (through low-intensity land-use) in combination with declining size of population (due to high rate of outmigration). Shrinkage, however, is, on the intra-urban level, spatially differentiated. Population, paradoxically, most intensively declines in the least financially demanding land-uses and grows in the most expensive land-uses for public administration. As population and urban structure development prove to have strong inertia, this land-use development constitutes a great challenge for a city’s future sustainability. The main objective of the paper is to explore the nexus between change in population density patterns in relation to urban shrinkage, and sustainability of public finance.
