Research on Economic Connection of Shenyang Metropolitan Area Based on the Gravity Model

This paper calculates the economic ties of cities in Shenyang Metropolitan Area using the gravity model, and uses the fracture point model to define the radiation intensity of Shenyang to other cities in the Metropolitan Area. The results show that: (1) From the perspective of the comprehensive strength of each city, Shenyang ranks first. However, the strength gap between other cities and Shenyang is large, exposing the unbalanced development of the metropolitan area. (2) From the perspective of the classification of economic connection among cities, Shenyang Metropolitan Area can be divided into four levels according to strong connection, relatively strong connection, relatively weak connection, and weak connection. Although Shenyang has strong or relatively strong links with other cities, most of the cities in the metropolitan area are weaker. (3) Seen from the location of the fracture points between Shenyang and other cities, they are located at about two-thirds of the distance between the two cities, and both are beyond the administrative area of Shenyang, which shows that it has a strong radiation and driving ability to the surrounding cities. At the same time, the comparative analysis with the provincial capital cities at the same level shows that Shenyang is in an advantageous position in the competition.
