m中国城市经济随着改革深入面临巨大转型,消费活力成为衡量一个城市经济发展能力和潜力的重要指标。文章以上海为例,利用辛普森指数、相关性分析法、核密度计算,研究了城市消费活力空间分布和热点识别、城市道路网与消费活力的相关性。结果表明:上海城市消费活力在空间密度上主要呈单核扩散模式,即由主城区中心向周边发展的态势;城郊区域出现的热点,可用以识别和评价政府规划的新型城镇中心的崛起和发展;道路节点密度与消费活力水平呈正相关关系,且相关程度较高(相关系数大于0.5);道路密度与消费活力水平呈微弱的正相关关系。总之,上海城市道路网建设对于消费活力形成及发展具有正面的促进作用。这些都可为城市道路规划与合理布局提供理论参考。
As Chinese urban economy faces huge transformation with the deepening of the reform, the consump-tion vitality acts as an important indicator for measuring a city's economic development capacity and potential. Taking Shanghai as an example,we investigated the spatial distribution and hot spot recognition of urban con-sumption vitality,and the correlation between urban road networks and consumption vitality using correlation analysis,Simpson index,and nuclear density calculation. The results show that the urban consumption vitality of Shanghai mainly takes a single-core-diffusion mode in the spatial distribution of density and presents the trend of developing from the main city center to the periphery. The consumption vitality hot spots appearing in subur-ban areas can be used to identify and evaluate the rise and development of new town center planned by the gov-ernment. There is a positive correlation between the node density of the road networks and the level of consump- tion vitality . The value of the correlation coefficient is above 0.5. The correlation between the density of road net-works and the level of consumption vitality is positive,but weak. In short, the construction of city road networks promotes the formation and development of consumption vitality .
