The different conditions of big developing countries lead to different spatial structures,such as multiple structure,concentric structure,and gradient structure,etc. As a result,industrial layout in big developing countries ap-pears in three modes: the industrial chain mode based on resources,the industrial developing zone mode supported by policies,and the industrial cluster mode oriented at the market. Different industrial layout modes determine the different economic layout modes; therefore,big developing countries should choose,adapt and upgrade the mode of economic lay-out according to the regional spatial structure.%发展中大国的要素禀赋存在显著差异,由此形成的不同的空间结构:多元结构、圈层结构、梯度结构等,并呈现出非均衡性、适应性等特征,导致发展中大国的产业布局模式表现出三种模式:以资源为依托的产业链条型布局模式、以政策诱导为依托的产业园区型布局模式及以市场引导依托的产业集聚型布局模式。不同的产业布局模式决定不同的经济布局模式,发展中大国应根据区域空间结构合理选择并适时促进经济布局模式的调整和升级。
