The city region has emerged as an important form of regional development and governance. However, the dynamics of spatial inequality in city regions are misunderstood. This study examines the Yangtze River Delta (YRD) to determine the spatiotemporal evolution of regional inequality across prefecture-level municipalities from 1990 to 2018. It finds that regional inequality has steadily increased since the 1990s but has declined somewhat in recent years. This is associated with faster growth and higher upward mobility of central regions in the early reform period and increases in the upward mobility of the periphery in recent years. The gradient-distance curve of the Shanghai-centered economy sharpened and then flattened, indicating the polarization of growth in the core regions, followed by the diffusion of development and improved regional integration. However, the core-periphery remains stronger within provinces between provincial capitals and other regions. Despite regional integration and peripheral development, the problem of spatial exclusion and core-periphery structures persists. More attention needs to be given to the core-periphery relationship and the development of peripheral regions to promote regional integration and reduce spatial polarization. [ABSTRACT FROM AUTHOR]

Most existing studies on shrinking cities focus on identifying and characterizing population contraction at the city scale and lack an in-depth exploration of the mechanisms of population contraction and daily life scenarios at the street scale. To fill this gap, this study employed semi-structured interviews and participant observation to analyze the street vitality and mechanisms of operation of Dongda Street in Rugao County of Jiangsu Province in China. The study found the following. First, the interspersed urban renewal has allowed residents to retain their original lifestyles and time-space routines, and they continue to enact an endogenous street ballet. Second, new residents gradually develop new lifestyles and time-space routines in the streets, showcasing an exogenous street ballet. Third, both groups jointly perform hybrid street ballets in their daily lives through close public interactions. These findings suggest that while Dongda Street is an aging neighborhood, the survival of the original street pattern and old buildings has allowed the neighborhood to retain its historical flavor. Additionally, the moving in of creative industries and merchants injects new vitality into the neighborhood. These findings examine daily street life in the context of population contraction and help break the stereotypes of population contraction. • The interspersed urban renewal has allowed local residents to retain their original endogenous street ballet. • New residents gradually develop time-space routines in the streets, showcasing an exogenous street ballet. • Both groups jointly perform hybrid street ballets in their daily lives through close public interactions.

Abstract The rapid increase of temporary migrants in large Chinese cities has led to the need for a nuanced and comprehensive understanding of the factors contributing to the influx. However, previous investigation into this subject has been undermined by an oversimplification of the concepts and measurements related to settlement intentions and migrants' social network. This study uses a combination of data from a 2013 nationwide survey and multilevel logit regressions to investigate the settlement intentions of 12,807 rural-urban migrants across eight cities in China. It especially focuses on the ways in which social ties between migrants and people in their destination cities shaped their intention to settle there. This study makes an innovative contribution to the literature in three ways. First, it distinguishes between migrants' ties to non-residents (other migrants from the same place of origin), kin residents (local residents who are kin), and non-kin residents (local residents who are not kin). Second, it distinguishes between interactive social ties and supportive social ties. Third, it uses multiple indicators to measure the intention of migrants who decide to permanently settle, as well as hukou transfer and housing ownership. Findings from our analysis indicate that the newly formed intergroup ties of migrants and their existing intragroup ties exert different impacts on their intention to settle. Specifically, migrants' newly formed ties with non-kin residents are positively linked to their settlement intention, while their ties to non-residents are negatively associated with their settlement intention. Our findings also indicate that the social ties of migrants have different effects on the different dimensions of their settlement intention. The social ties of migrants play an important role in their permanent settlement and housing ownership intentions, but their effect on hukou transfer intentions is relatively weak. Additionally, our research discovered that supportive social ties play a more important role than do interactive social ties in shaping migrants' settlement intention. Highlights • Rural migrants who retain kin-based and home-based ties with other migrants in destination cities tend to have a weaker intention to settle in cities. • Rural migrants who maintain kin-based ties with local residents or actively construct social ties with non-kin local residents tend to have a stronger intention to settle in cities. • Compared to interactive social ties, supportive social ties play a more significant role in influencing migrants' settlement intention. • Rural migrants' social ties play different roles in different patterns with regard to settlement intention.
