Abstract In this article, the concept of gravitational fields applied to trade is revisited and extended to multiple economic variables, integrated within Moran’s I analysis. Following Isard’s thinking, emphasis is placed on the use of the gravitational model in spatial analysis, with the intent of theoretically developing an econophysical methodology. To map the interactions between the economic forces generated by the individual gravitational fields of various regions, the principle of vector superposition is applied to provide the resulting total field. Through a cross-analysis that employs gravitational fields and Moran's I, spatial concentration phenomena in the American market will be studied. JEL classification: A12, B1, B27, C31, F10, F20, R30.
