能源富集区产业结构时空差异及演化

Research on spatio-temporal difference and evolution of industrial structure in resource-rich area

针对能源富集区产业结构时空差异与演化分析不足的问题,该文运用利用HHI指数、空间基尼系数和产业结构差异系数对1995—2014年陕甘宁蒙能源富集区产业结构的时空格局差异及演化特征进行研究。结果表明:1995—2014年能源富集区第二产业比重>第三产业比重>第一产业比重,表现为"二三一"产业结构模式,是典型的以第二产业为主导的产业结构;1995—2014年陕甘宁蒙能源富集区第一产业集聚程度围绕0.04呈现小幅度变化趋势,第二、三产业的集聚程度下降趋势明显;通过考虑经济总量的分析,发现各次产业相对量仍呈集中态势,得出陕甘宁蒙能源富集区县域三次产业相对集中的结论;能源富集区三次产业结构的空间差异性不显著,年际变化较小,能源富集区需要加快推进产业结构优化升级以带动经济的可持续发展。

According to the lack of analysis of the spatial-temporal patterns and evolution characteristics of industrial structure in energy rich area,this paper used the HHI,the spatial Gini coefficient and the industrial structure difference coefficient to study the spatial-temporal patterns and evolution characteristics of industrial structure in Shaanxi Gansu Ningxia Mongolia energy rich area from 1995 to 2014.The results showed that the industrial structure presented a type of＂second〉third〉first＂,the secondary industry was the leading force to promote the economic development of resource-rich area.The industrial concentration degree of the first industry mainly around the 0.04 showed a small change trend,the downward trend of the second industry and the third industry were significant.Considering the economic aggregate of each region,it is found that the relative number of industries is concentration situation,which can get a conclusion is that the industrial structure of resource-rich area of Shaanxi Gansu Ningxia Mongolia Region is relative concentration.The spatial difference of the three industrial structure in resource-rich area is not significant,the inter annual change is small,energy rich areas need to accelerate industrial restructuring and upgrading to promote sustainable economic development.
