Analysis of regional comparative advantage and spatial distribution of Jiaozuo Rehmannia

Using the method of aggregated advantage index, this paper analyzes the comparative advantage of Rehmannia areas in Jiaozuo, which are then expressed in the map by GIS software. The results show that there are significant regional differences of Rehmannia production, and the townships of production advantages are mainly located in the central and southern parts of Jiaozuo. According to the principle of comparative advantage, it is suggested that Rehmannia production areas be adjusted, and the rational distribution and specialized production for the Rehmannia production be implemented. At last, reasonable measures and suggestions for the Rehmannia development are proposed.
