2. Rupture or continuity: A debate with an open end
The introduction of the term urban renewal has not really been
accompanied by a clarification of its contents. The urgency of the
problems in the large high-rise social housing estates has led to a particular,
and restrictive, interpretation. But a review of the laws SRU
and Borloo on the one hand, and the observation of the practice of
urban renewal on the other, indicate two different approaches to
urban renewal that exist alongside each other Table 1.
2.1. Urban renewal through the market mechanism
The first approach is to be found in operations of urban renewal realised
in line with a logic of reinserting the areas into the land and real
estate market. Usually, these operations are not officially labelled
urban renewal. They are realised by the local planning authorities
with local funding and using common procedures of urban (re)development.
Such operations mainly concern run-down brownfield and
mixed areas near city centres, where the possibilities of a rupture with
the old situation and of an inversion of the downward spiral seem to
be more realistic. Because these areas are situated in the proximity of
urban centres, and because they can rather easily be connected to
urban transport systems, they have a certain potential to attract private
investors.
2，破裂或连续：一个结果开放的辩论
以明确内容的方式，对专业术语“城市革新” 的介绍还没有真正地完成。在大型高层社会住宅小区的紧急问题导致了一个特定而有限制的解释。但一方面重审法律SRU 和Borloo，另一方面对城市革新的实践进行观察，显示了城市革新的这两种不同的方法相互依存，如表一。
2.1，通过市场机制来革新城市
第一种方法是在以符合逻辑地将此区域重新插入土地和真实的房地产市场来有秩序地实现城市革新的操作。通常情况下，这些操作没有被正式地贴上城市革新的标签。它们以地方规划当局用当地资金和使用常见的城市(重新)发展程序来实现。这样的操作主要关系到破旧的棕色地带和城市中心附近的、有因为陈旧而可能破裂的、恶性循环的倒置显得更为现实的混合区域。因为这些区域接近市中心，且易于被连接到城市交通系统，所以它们有一定的潜力吸引私人投资者。
怎么不给好评？？？？？？？？？？？？？
