基于手机信令数据的上海五个新城独立性动态特征与趋势研究OA北大核心CHSSCDCSTPCD

Becoming independent and comprehensive nodes is one of the important requirements of Shanghai's 14th Five-Year Plan for the development of the five new towns.Based on the cell phone signaling data in 2014 and 2020,this paper measures the independence characteristics and trends of the five new towns in Shanghai in terms of commuting and non-commuting activities.The results show that although the scale of job and housing are balanced,the actual job-housing feature tends to deteriorate.The proportion of commuting and living trips from certain new towns to the central city reaches more than 20%.The five new towns are becoming more attractive to the surrounding areas for employment and activities,but remain less attractive to the central city.In addition,rail transit may have enhanced the residency of the new towns,but it has not enhanced the attractiveness of the new towns to the central city.It is found that the five new towns are still in the stage of transformation from semi-independent towns to self-balancing independent new towns.The independence of the five new towns still has much room for optimization.
