The degree of coordinated development of rice mechanization and regional economy (CDME) is related to the sustainable development of regional economy, but there is little research on the coordination between the two. This paper constructs an evaluation index system for the coordinated development of rice mechanization and regional economy based on the relevant research. Then this paper obtains the weight of each index combining the entropy method and the analytic hierarchy process. Finally, this paper conducts an empirical analysis on the coordinated development of rice mechanization and regional economy based on the coordination degree model in the country from 2008 to 2018.
