Urban Dreams of Migrants: A Case Study of Migrant Integration in Shanghai

[视频介绍]
简介:An unprecedented human mobility has driven the rapid urbanization around the world. In China, the fraction of population dwelling in cities increased from 17.9% to 52.6% between 1978 and 2012. Such large-scale migration poses both significant challenges for policymakers and important questions for researchers. In this talk, I will introduce our study of the process of migrant integration. Specifically, we employ a one-month complete dataset of telecommunication metadata in Shanghai with 54 million users and 698 million call logs. We find systematic differences between locals and migrants in their mobile communication networks and geographical locations. For instance, migrants have more diverse contacts and move around the city with a larger radius than locals after they settle down. By distinguishing new migrants (who recently moved to Shanghai) from settled migrants (who have been in Shanghai for a while), we demonstrate the integration process of new migrants in their first three weeks. Moreover, we further investigate migrants’ behavior in their first weeks and in particular, how their behavior relates to early departure.
