【摘要】：多中心城市被认为是缓解大都市地区职住通勤问题的一种空间模式。但在规划实践中,往往片面强调"田园城市"的分散理念,自足性的职住议题也仅关注就业、居住的总量平衡,忽视了规模集聚的正向外部性、职住空间匹配的结构性问题。基于就业门类的结构性问题,对多中心城市的功能和交通组织进行理论梳理,辨析多中心职住空间的组合模式。研究发现,职住完全匹配的多中心(组团)模式存在明显的理论冲突,无法付诸规划实践,进而提出了非完全结构匹配的多中心职住假说模型:在就业多中心均衡性的前提下,保障通勤距离受限群体的职住邻近性、满足本地居民的就业设施的类型完善,通过就业中心的专门化集聚实现"整体大于局部之和"的多中心优势。并以广州为例,运用假说模型进行了多中心职住匹配的实证探索。
[Abstract]:Multi-center cities are considered to be a spatial model to alleviate the problem of occupational and residential commuting in metropolitan areas. However, in planning practice, the decentralized concept of "rural cities" is often emphasized, and self-sufficient job and housing issues focus only on employment. The balance of the total amount of residence ignores the positive externality of scale agglomeration and the structural problem of job space matching. Based on the structural problems of employment category, this paper makes a theoretical analysis of the function and transportation organization of multi-center cities. It is found that there are obvious theoretical conflicts in the multi-center (group) mode which is perfectly matched between the occupation and residence, which can not be put into practice. Furthermore, this paper puts forward the hypothesis model of multi-center occupation and housing with incomplete structure matching: under the premise of employment multi-center equilibrium, it can guarantee the proximity of the commute distance limited group and satisfy the perfection of the employment facilities of local residents. Through the specialized agglomeration of the employment center, the multi-center advantage of "the whole is greater than the sum of the parts" is realized. Taking Guangzhou as an example, the hypothesis model is used to carry on the empirical exploration of the multi-center occupation and residence matching.
