Through the construction of the comprehensive evaluation index system and the coordination degree model of the rural in- frastructure and the rural economic development level, the author carries out an empirical analysis on the rural infrastructure and economic coordinated development in the country's 31 regions. Research shows that the gap between the levels of the development of the rural in-frastructure in China is large, presenting the gradually reducing gradient distribution from the east to the west. The rural infrastructure de- velopment level has significant positive correlation with the level of economic development. For those provinces of the high development level of the rural economy, the infrastructure construction level is also relatively high. From the view of the coordination degree, it presents the obvious "dumbbell" shape, and there are more provinces which belong to the high quality coordination and the serious imbalance, with the coordinated degree in the eastern regions obviously higher than that in the central and western regions. 展开更多
