The paper selects Chengxian Street in Nanjing, the ancient capital of six dynasties as an example, which has experienced some regeneration and reconstruction in history. After a long period of development, it has developed into a characteristic street with a variety of functions. This paper is based on the perspective of urban regeneration and urban design with literature, field survey, and other research methods. The paper then mainly analyzes the concepts of regeneration and design, including the classical theories and successful cases. After that, this research divides the evolution of Chengxian Street into stages and analyzes the characteristics, respectively. It shows that Chengxian Street had undergone five stages since the Ming dynasty: First, the period of prosperity 1381–1853; second, the period of destructive destruction 1853–1864; third, the period of restoration and reconstruction 1864–1949; fourth, the period of local regeneration 1949–2010; and now in a period of comprehensive regeneration. The current practice is oriented toward the objectives of organic regeneration. In addition, it also focuses on the problems existing in the recent regeneration and reconstruction of Chengxian Street after two comprehensive regeneration, including lack of traffic calming, several pedestrian spaces are not accessible, lack of public communication, poor street landscape, lack of local characteristic, and some street scale are unreasonable, etc. Finally, the paper gives further thoughts on the regeneration and design of Chengxian Street about traffic optimization, public communication, street landscape, street characteristics, and so on in order to promote the development of characteristic streets.

Through the construction of a population flow and migration relationship matrix, this paper analyzes population flow and migration in the Yangtze River Delta urban agglomeration during the Spring Festival travel rush and daily period. This paper also studies the urban network spatial structure characteristics and the influencing factors from the perspective of inter-provincial population flow and migration. The results show the following: (1) as a central city, Shanghai has a significant siphon effect, with Suzhou, Nanjing, Hangzhou, Ningbo, Wuxi and Changzhou accumulating 86.95% of the incoming population. The Shanghai–Jiangsu cross-border floating population is active and accounts for 40.83% of the total mobility scale in the same period. The population flow and migration network in the Yangtze River Delta urban agglomeration shows obvious hierarchical characteristics. The secondary network relationship during the Spring Festival travel rush is the main migration path, while the first-level network relationship in the daily period is the main flow path. (2) Three indicators, namely, the network density, mean centrality, and control force based on the population flow and migration, consistently show that the Yangtze River Delta urban agglomeration network presents a strong connection state with the formation of a local cluster structure, highlighting that the city tightness in terms of population flow and migration also has dual attributes, which refers to “the restriction of the geographic space effect” and “overcoming the friction of space”. (3) Economic scale, political resources, industrial structure, and the historical basis are important factors influencing the formation of population flows and migration networks. Employment opportunities and labor wages are key guiding factors of the population migration direction, and spatial distance is a conditional factor influencing the formation of population flows and migration networks. The inter-provincial boundary, temporal distance, and transboundary frequency are the decisive factors for the formation of network patterns of population flow and migration.
