摘要:
随着网络的快速发展,实体商业的模式和业态面临着巨大压力和挑战,导致城市形态和城市结构随之产生变化。长期以来,课题组通过Web数据挖掘对长春市城市商业中心的空间效率进行客观性研究。本文针对长春市商业中心空间效率的研究,首先依据2016全年大众点评网的餐饮数据,对商业中心的空间分布形态进行剖析,特别是通过空间句法的理论与方法对点评数据进行相关性分析;其次,结合空间句法对城市形态的定量分析,剖析长春市商业空间分布与现状城市形态结构之间的矛盾;最后提出了疏解原有城市形态中心功能以完善中心城区空间结构的建议,以期增强长春市中心城区的空间效率。

Abstract:
With the rapid development of Internet, the patterns and forms of entity business is facing great pressure and challenge, lead to urban form and urban structure changes accordingly. For a long time,our research group study objectively of space efficiency of Changchun commercial centers through web data mining.In this paper, based on catering data from dianping.com in 2016, a study of commercial center of Changchun City was carried out.In addition, space syntax was used to analyze the urban morphological center of Changchun City. First of all,Through comparison between urban commercial center and urban morphological center based on Dianping Data and space syntax theory and method, an obvious correlation between them was found.Secondly,combined with quantitive space syntax analysis, some deviations of their exsiting space structure and distribution of commercial centers in Changchun was found. Therefore, this study gave a suggestion about the untwining measures of the original functions of urban morphological center and the present space structure melioration of urban commercial center, in order to increase the space efficiency of Changchun city center.
