Abstract: In view of the problems of cross-regional commuting, such as the difficulty in traditional data integration and the high requirement for data timeliness, first of all, this paper combines the characteristics and trends of cross-regional transportation at home and abroad, and proposes the emerging connotations of regional commuting in the new era, such as functional connection and network structure, as well as the core value of people-oriented transportation travel efficiency and quality improvement.Secondly, based on the big data of Internet location, this paper proposes the concept definition and identification method of commuting in the new era at the regional scale, and further verifies the feasibility of the technical methods from multiple dimensions such as cities, districts and counties, and cross-city.Finally, taking Shanghai and its surrounding cities as examples, this paper analyzes the characteristics of cross-city commuting at different scales such as cities, districts and counties.Generally, it presents features such as “networked convection” and “near-area flowing”, further optimizing and empirically verifying the universality and feasibility of cross-regional commuting methods at different scales.
