However because the resource is of exhausting character, this means that the region has hidden troubles of economic depression. The paper analyzes the formation of resourceful region and the law of resourceful regions economic development, and then the paper brings forward that the resourceful region has a potential danger of economic depression. Considering Chinas economic development practice, the paper puts forward a basic way of thinking. That is: we must attach importance to the problem of industrial structure when we pay attention to existing resource advantage in order to avoid the simplification of regional industrial structure and to avoid entering a vicious cycle.展开更多

文摘The resource advantage of resourceful region has made the region develop very fast. However because the resource is of exhausting character, this means that the region has hidden troubles of economic depression. The paper analyzes the formation of resourceful region and the law of resourceful regions economic development, and then the paper brings forward that the resourceful region has a potential danger of economic depression. Considering Chinas economic development practice, the paper puts forward a basic way of thinking. That is: we must attach importance to the problem of industrial structure when we pay attention to existing resource advantage in order to avoid the simplification of regional industrial structure and to avoid entering a vicious cycle.
