By constructing an evaluation index system of economic transform capacity of the resource-regenerated cities with 17 indexes, this paper uses the entropy weight TOPSIS method to set index weight and calculates the economic transformation capacity of 11 resource—regenerated cities during 2013 to 2016 in China. Then beta convergence test conducted on the economic transformation capacity of those cities. Results show that about 9 cities have an obvious changes and the ability of economic transforming gap between cities have been narrow. Economic adjustment is a key index that decides economic change. 11 cities economic transformation capacity show they have beta convergence ability, which means that the lag behind economic transformation ability cities have “catch up effect” with developed regions in their developing period. It shows that 11 cities still need to strengthen the economic adjustment, further reduce the gap and improve the ability of the economic transformation.
