In order to study the development of the “fivemodernization synchronization” in China and construct an evaluation index system,this paper uses factor analysis to evaluate and analyze their development situation in China,and then builds the VAR model to make an empirical analysis on the “five coordinations”.The testing result shows that the variable sequences is I(1) and there is a cointegration relationship,but Granger causality test result shows that insufficient integration and lack of interaction among the five “modernization” really exist.Further results,through VAR (1) model,impulse response and variance decomposition,show that the “fivemodernization” are interrelated and necessary.Finally,this paper proposes several policy suggestions such as strengthening the development of “fivemodernization synchronization”,from the following several aspects: promotion of agricultural development by the industry,urban and rural integration development,deepening the “fivemodernization” fusion and advocating innovation and green development way,etc.
