我国经济发展的空间分布,客观上形成了东、中、西三大地带。就经济技术发展水平看,基本上是东高西低梯形排列;就丰富的矿产资源和广阔的空间而论,基本上是自西向东呈梯形下降。河南地处中华腹地,位于这两个逆向梯度的中间地带,不但是联系全国东南西北和沟通各地经济技术交流的? The spatial distribution of China’s economic development has objectively formed the three eastern, central and western regions. As far as the level of economic and technological development is concerned, it is basically a trapezoidal arrangement of east, west, low and west. In terms of abundant mineral resources and vast space, the trapezoidal decline basically occurs from west to east. Henan is located in the hinterland of China, located in the middle of these two adverse gradients. It not only links with the southeast, northwest and the whole country in economic and technological exchanges.
