Northeast China (or Dongbei) 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. This study takes a perspective of inter-city human movement to investigate the pattern of socioeconomic interactions at a short-term regular basis (e.g., daily or weekly) between cities in Northeast China provinces and in the rest of China. An exploratory flow clustering method, flowAMOEBA, is employed to discover new patterns of interaction from empirical trip data at the individual level. Our research is supported by big data of human movement extracted from mobile device positioning requests that are collected by Baidu Map. Population effects are examined with selective trip clusters detected to demonstrate the potentials of our approach to unveil the true preference of trip making and to help form new hypothesis with discovered patterns.
