全球各地，有组织的都市房地产拥有者，正以国家主权去设计一个新政府型式以保护其利益。经由此力量来征税及提供共同的服务，倡导的人主张商业改善区域可有效地维护户外公共场所的清洁及安全。相较之下，我们更应该检查此种公开捐赠、私人管理的机构，及质疑他们对政治、经济、社会所做贡献与对都市空间破坏的程度。

Organized urban property owners in contexts throughout the globe are using state authority to create a new form of government to protect their interests. With the power to impose taxes and provide collective services, proponents claim that business improvement districts (BIDs) effectively clean and secure outdoor public spaces. In contrast, it is important to examine the proliferation of such publicly endowed and privately managed organizations and question the extent to which they contribute to the political, economic, social and spatial fragmentation of the urban realm.
