文章以京津冀工业为研究对象,运用空间基尼系数、赫芬达尔指数、行业集中度和区位熵指标,从纵向和横向两方面考察了三省市的工业集聚度。研究发现:2003~2012年京津冀工业集聚度呈波动上升后平稳的趋势,且整体呈“天津—河北—北京”的梯度态势;从横截面分析可知北京、天津和河北的各个工业部门之间互补的同时也存在严重的产业同构现象,大部分高能耗高污染部门集中在天津和河北。据此,提出三省市应加强制度合作,同时联合扩大工业规模,优势互补构造完整产业链的政策建议。
Taking Beijing, Tianjin and Hebei industry as the research object, this paper examines the industrial agglomeration of the three provinces and municipalities from both vertical and horizontal using the spatial Gini coefficient, Herfindahl index, industry concentration and location entropy. The study found that the concentration of industrial agglomeration in Beijing, Tianjin and Hebei showed a steady trend from 2003 to 2012, and the overall trend was “Tianjin-Hebei-Beijing”. According to the cross-sectional analysis, the industrial agglomerations in Beijing, Tianjin and Hebei There is also a serious phenomenon of industrial isomorphism, which is complementary to each other. Most high-energy and high-polluting industries are concentrated in Tianjin and Hebei. Accordingly, it is proposed that the three provinces and municipalities should strengthen institutional cooperation and at the same time, jointly promote the policy of expanding the industrial scale and complementing the advantages of the complete industrial chain.
