由于历史原因,长期以来,我国城市工业企业布局分散,且与居民住宅区、金融商贸区、风景旅游区高度混杂。随着城市化进程的加快,这些企业与周边环境的反差日益强烈,也严重影响了所在城市综合地位的提升。针对这一现状,许多大中城市相继制订了中心城区工业企业实施腾笼 Due to historical reasons, for a long time, the distribution of urban industrial enterprises in China has been decentralized, and it is highly mixed with residential residential areas, financial and business districts, and scenic tourist areas.

In response to this situation, many large and medium-sized cities have successively formulated central industrial enterprises to implement cages.
