| 摘 要： | 进入新世纪,中国区域经济发展的基本格局是将加快北移西进,建设黄河经济带是中国国民经济建设重点北移西进的必然趋势。本文认为,经济带的形成是一个复杂的过程,具有标度不变性或自相似性,即经济带的形成具有分形特征,工商业企业是经济带形成的分形元。从Zipf维数来看,长江经济带比黄河经济带发育较为成熟,因此本文以长江经济带为例,运用形状类似于四角星型的DLA分形模型,从动态的角度来认识这一非平衡过程,从另外一个角度分析了长江、黄河经济带的形成机理。 |

| Abstract: | As the new century enters,the basic structure of Chinese regional economic development is speeding up the North-westward migration.Therefore,constructing economic belt around Yellow River is necessary to make the emphasis of national economy in China's North-westward migration. In this article,it is complex for economic belt to form with scale invariance or comparability,that is,the formation of economic belt has the characteristic of fractal,and enterprise of industry and commerce is the fractal unit which builds the economic belt.From Zipf dimension,the growth of economic belt around the Yangtze River is more mature than around the Yellow River.Thus,this article takes economic belt around the Yangtze River for instance,makes use of DLA fractal model whose shape is similar to foursquare star,and understands this unbalanced process dynamically and analyzes the formation mechanism of economic belts around the two rivers in another way. |
