西陇海兰新经济带节点城市的发展方向与产业分工

西陇海兰新经济带是我国西部大开发战略重点区域“两带一区”的重要组成部分。本文分析了西陇海兰新经济带节点城市发展与布局的总体特征,采用多层次多目标综合测度模型定量评价经济带上全部城市的综合竞争力,并把西安、兰州、乌鲁木齐确定为经济带上的一级节点城市,把咸阳、嘉峪关、宝鸡、酒泉、克拉玛依、哈密、石河子、库尔勒、天水、奎屯共10个城市确定为经济带上的二级节点城市。进而以此为依据,对西陇海兰新经济带各级节点城市进行发展方向定位和产业分工。

The development orientation and the industrial division of the node cities along the Western Long Hai-Lan Xin Economic Zone

The Western Long Hai-Lan Xin Economic Zone is an important part of the "two zones and one district" in the great strategic development of western China. The authors analyze the overall characteristics of the node cities along the Western Long Hai-Lan Xin Economic Zone, and considers that though the cities are distributed concentratively and the urbanization level is higher than that of the western region and the whole country, yet the metropolises are far away from each other and no big cities lying between them. So three weak zones come into being along the Western Long Hai-Lan Xin Economic Zone and the cities' spatial distribution of "point-axis" type will still exist. According to multi-hierarchical and multi-target comprehensive measurement model, all the cities' comprehensive competitiveness along the zone is evaluated. Xi'an,Lanzhou and Urumqi are considered as the first class node cities along the zone and Xianyang,Jiayuguan,Baoji,Jiuquan,Karamay,Hami,Shihezi,Korla,Tianshui and Kuytun are considered as the second class node cities along the zone. Based on this, the development orientation and the industrial division of the node cities along the Western Long Hai-Lan Xin Economic Zone are put forward. Xi'an-Xianyang metropolitan district is considered as the first class key node city in western China and the east of the Western Long Hai-Lan Xin Economic Zone, which should be constructed as the core of the Guanzhong Economic District and Guanzhong New High-tech Industrial Development Zone. Lanzhou-Baiyin metropolitan district is considered as the first class subordinate node city in western China and the first class key node city in the middle section of the Western Long Hai-Lan Xin Economic Zone, which should be constructed as the core of the multi-nationality economic zone in the upper reaches of the Yellow River. Urumqi-Changji-Miquan-Fukang metropolitan district is considered as the second class key node city in western China and the first class key node city in the western section of the Western Long Hai-Lan Xin Economic Zone, which should be constructed as the core of the northern Tianshan Mountain economic zone. Baoji,Tianshui,Jiuquan-Jiayuguan-Yumen,Hami,Kuytun-Dushanzi-Usu are considered as the second class subordinate node cities in western China and the first class subordinate node cities in the Western Long Hai-Lan Xin Economic Zone, which should be constructed as the five “piers” in the weak zones of the continental bridge to support the whole economic zone.
