北京城市总规中“两轴”的现状产业特征和空间集聚态势分析

Characteristics of Industrial Development and Spatial Agglomeration of "Two Axes" in Beijing Urban Master Plan

在北京市历次总体规划中,长安街和中轴线作为北京重要的城市轴线被给予重点关注,但是对于两条轴线产业发展状态的定量分析相对不足。以经济普查的微观个体企业数据为基础,利用GIS空间分析方法,对"两轴"范围进行界定,并分析"两轴"产业特征及产业空间集疏规律。结果发现:(1)"两轴"核心区域在北京经济发展中占有重要地位,尤其是长安街轴线;(2)"两轴"的经济活动强度存在明显的"东高西低,北高南低"空间特征,且空间发展不平衡有进一步扩大的趋势;(3)"两轴"出现了金融化的趋势。

In all of the Beijing’s master plans, Chang'an Street and the central axis, as important urban axes, have been given great attention, but the scientific data analysis on the industrial development of the two axes is relatively inadequate. This study employs unique dataset from the economic census and kernel density estimation (KDE) to define spatial range of the “two-axis”. Based on this, characteristics of industrial development and spatial agglomeration of micro-enterprises in “two-axis” are analyzed. The results show that:(1)"two axes" play an important role in the economic development of Beijing, especially the axis of Chang'an Street;(2) the "two axes" have obvious features of imbalanced development, which is "high in the east and low in the west;high in the north and low in the south", and importantly, the gaps among those areas are growing;(3) high-end services have been gradually dominated in the "two axes" in Beijing.
