Made in China? Concepts and Strategies of Urban Brownfield Development for Abandoned Industrial Sites in Chinese Coastal Mega-Cities

该项目研究了废弃的市中心工业用地的棕地再开发的概念和策略，以及在上海、广州和深圳的实施情况。其出发点是针对旧制造基地的积极和差异化升级政策的新政策的演变。由于中国经济正在进行转型，棕地重新开发的进程正在继续或刚刚开始。该项目希望解释尚未系统调查的各种复杂的重新开发战略，以及它们的驱动因素和具体特点。除了地方增长战略，城市发展和城市规划的合理性以及房地产开发余地的变化将被纳入解释方法，考虑到土地使用权和基于改革的租赁制度的土地交易。迄今观察到的动态城市发展似乎遵循一种简单的盈利模式，其特点是密集、增加建筑高度和城市向城市周边地区扩张的力量。该项目想要系统地解释这一领域的具体发展路径，并展示具体的政治和经济参数、治理安排和规划思想的相关性。它将试图证明有一种特殊的“中国方式”，与已知的国际发展战略大相径庭，并产生各种针对特定地点的重建概念。由于国家拯救有价值的农业区的政策，最近在增长地区的市中心加强土地利用的压力有所增加。因此，必须解释为什么以及何时在重建后的旧制造地点仍保持相对较低的建筑密度。在城市规划方面，该项目着眼于行为者如何平衡以下相互矛盾的主张：创造额外的建筑面积、保留具有重要历史意义的工业遗产、改善升级后的开放空间的普遍可达性以及创造与城市营销目的具有一定相关性的城市设计“亮点”。关于城市设计，该项目分析了建筑存量的含义，以及建筑存量如何重新使用、补充、叠加、忽视和更新。它将确定由开发商、土地所有者、使用者和规划机构之间复杂的互动所塑造的城市设计模式和愿景。

The project investigates concepts and strategies of brownfield redevelopment for abandoned inner-city industrial sites and their implementation in Shanghai, Guangzhou and Shenzhen. Its starting point is the evolution of new policies of pro-active and differentiated upgrading policies for former manufacturing sites. As a result of the on-going transformation of the Chinese economy, the process of brownfield redevelopment is continuing or only starting to take off. The project wants to explain the complex variety of redevelopment strategies, which have not yet been investigated systematically, and their drivers and specific features. Besides local growth strategies, the rationality of urban development and urban planning and the changing leeway of real estate development is to be incorporated into the explanatory approach, taking into account land use rights and land transactions based on a reformed leasehold system. The dynamic urban development observed so far seems to follow a simple model of profit-making characterized by the forces of densification, increasing building heights and urban expansion into peri-urban areas. The project wants to explain the specific development paths in this field systematically and to demonstrate the relevance of specific political and economic parameters, governance arrangements and planning ideas. It will try to demonstrate that there is a particular “Chinese way”, deviating significantly from known international development strategies, and producing a great variety of site-specific redevelopment concepts. The pressure to intensify land uses in the inner cities of growing regions has recently increased as a result of national policies to save valuable agricultural areas. Thus, it has to be explained why and when relatively low buildings densities are kept on former manufacturing sites despite redevelopment. In terms of urban planning, the project looks at how actors balance the conflicting claims of creating additional floor space, keeping historically significant industrial heritage, improving the general accessibility of upgraded open spaces, and creating urban design "Highlights" with a certain relevance for city marketing purposes. With reference to urban design, the project analyzes the meanings attributed to the building stock and how the latter is re-used, complemented, superimposed, neglected and renewed. It will identify the urban design models and visions that are shaped by the complex interactions of developers, landowners, users and planning bodies.
