Empirical Research on Planning Cultures in the Context of Open Space, Housing and Retail Development in Shrinking Cities and City Regions

拟议项目的目的是在从以增长为导向的规划向适应多维收缩过程过渡的过程中，从理论上和经验上寻找地方和区域规划文化变化的答案。具体而言，将获得新的见解，了解由指导决策和行动的价值和规范、意义分配和感知模式组成的非正式体制结构的持续和变化。在这里，需要调查政治话语的适应性、行动的逻辑和行动模式与新规划概念、工具和程序的创造和应用之间的相互关系。考虑到发展路径以及行动的不同空间参考水平及其相互依赖性，将分析正式制度世界（作为正式行动框架的各自规划系统）与非正式制度世界（包括话语和行动认知维度的非正式操作框架）之间的复杂相互关系。为此目的，将使用从制度和行动理论中得出的模型，通过基于四个案例研究（Gelsenkirchen, saarbr<e:1> cken, Halle, Chemnitz）的比较分析来探索城市和区域一级规划文化的配置和动态。通过三种不同的方式进行比较：首先，通过选择开放空间、住房和零售开发，在机构设置和参与者组合方面不同的规划部门领域将被转移到焦点。因此，根据对收缩条件下的部门适应情况的比较，预期会有关于规划文化变化的部门差异的新发现。其次，通过比较前西德和东德的案例研究，该项目将确定在统一后基于冲突的政治制度以及不同的经济和人口框架的规划文化中不同的发展道路对适应萎缩的影响。第三，通过比较旧联邦州（Gelsenkirchen和saarbr<e:1> cken）和新联邦州（Halle和Chemnitz）的两个类似收缩发展路径的案例研究，将研究特定的地方和区域规划文化对收缩适应策略的影响，以及由于共同的正式和非正式的规划制度世界的相似性。

The aim of the proposed project is to find theoretically and empirically grounded answers to the question in what sense a change in local and regional planning cultures takes place during the transition from growth-oriented planning towards adaptations to multidimensional shrinking processes. Specifically, new insights will be gained into persistence and change of informal institutional structures being composed of values and norms, assignments of meanings and perception patterns which guide decision making and action. Here, investigations into the adaptation of political discourses, logics of action and action patterns in interrelation with the creation and application of new planning concepts, tools, and procedures are needed. In consideration of development paths as well as different spatial reference levels of action and their interdependencies, the complex interrelationships between the world of formal institutions, which is the respective planning system as the formal framework for action, and the world of informal institutions, which means the informal operational framework comprising discourses and cognitive dimensions of action, will be analysed. For this purpose, using a model derived from institutional and action theories, configurations and dynamics of planning culture at the municipal and regional level will be explored by comparative analysis based on four case studies (Gelsenkirchen, Saarbrücken, Halle, Chemnitz). The comparison is designed in three contrasting ways: Firstly, by selecting open space, housing and retail development, sectoral fields of planning that differ in terms of institutional settings and constellations of actors will be moved into focus. Therefore, based on a comparison of sectoral adaptations under conditions of shrinkage, new findings with regard to sectoral variations of change in planning culture are expected. Secondly, by comparing case studies from the former West and East Germany, the project will identify implications for adaptation to shrinkage due to divergent development paths in planning cultures based on conflicting political systems as well as different economic and demographic frameworks after reunification. Thirdly, by comparing two case studies with similar development paths of shrinkage in the old federal states (Gelsenkirchen and Saarbrücken) on the one hand and in the new federal states (Halle and Chemnitz) on the other hand, the influence of specific local and regional planning cultures to adaptation strategies towards shrinkage will be examined alongside similarities due to common formal as well as informal institutional worlds of planning.
