Northeast China provinces, including Liaoning, Jilin, and Heilongjiang, have topped the chart in the number of “shrinking cities”, which experience population decline and lagged economic growth in the recent decades of Chinese urbanization. Urban shrinkage can be attributed to factors internal to cities including demographic change and suburbanization; it may also be attributed to economic decline as a mixture of internal and external aspects such as resource depletion, deindustrialization, or a lack of success in inter-city competition for investment. The latter generally leads to net out migration from the city region in search of jobs in the long run and the change of socioeconomic interactions between the shrinking city and other urban areas at a daily basis. In this sense, urban shrinkage can be conceptualized as an empirical phenomenon resulting from the interplay of changing factors of shrinkage at different spatial scales that produces a decline in population at the city level. This study takes a perspective at the inter-city scale and investigate the urban interaction in both short and long runs between cities in Northeast China provinces and in the rest of China. Benefitted from the recent advancement of big data technologies, human movement data at the individual level become widely available to represent a considerable proportion of population due to the proliferation of mobile devices with positioning capability enabled. This paper focuses on exploring the various patterns of human-activity-based interactions between the shrinking cities in Northeast China and the urban areas outside that region.
