西北五省矿业产业偏离份额分析

Shift-share analysis of mining industry in Inner Mongolia、 Shaanxi、Gansu、Ningxia and Xinjiang provinces

我国西北五省是矿业产业大省,其矿业产业的发育直接影响国内工业的发展。本文采用偏离份额分析法研究了2006~2011年内蒙古、陕西、甘肃、宁夏和新疆的矿业产业发展情况,旨在评价这些区域矿业产业的产业结构优劣和竟争力的强弱。研究结果显示:①产业竞争力是推动西北地区矿业发展的最主要力量;②产业结构水平低的劣势是阻碍西北五省矿业发展的关键因素;③西北五省的矿业发展目前以煤炭上游的开采和洗选业为主,并具有较强的竞争优势;④其他矿业产业的竞争优势尚未充分发挥。

The five northwestern provinces in China are strong in mining industries .Their development has deep impact on China's industry .In order to measure the industrial structure and competitive capacity , this paper uses shift-share analysis to investigate the development of mining industry in Inner Mongolia , Shaanxi ,Gansu ,Ningxia and Xinjiang .Our result shows :①Competitive capacity is the driving force of these provinces'mining industry ;② These five provinces are weak in industrial structure ,which hindered the development of their mining industry ;③ Coal mining and washing industry is the key industry in five northwestern provinces which has higher competitive capacity ;④Other industries have less advantage .
