京津冀地区工业结构趋同现象及成因探讨

利用我国第一次经济普查数据分析京津冀地区工业结构趋同现象,并采用计量模型探讨工业结构相似的影响因素。总体而言,京津冀区域内13个城市间工业结构存在一定的相似性,但相似程度随产业细分而显著下降。北京—天津—廊坊和唐山-邯郸-邢台是该区域内工业结构相似性最强的两个地区,前者同构主要发生在利润率高和市场潜力大的产业上,但中小类产业已呈现一定的分工格局;后者同构则主要发生在资源密集型产业上,同构在产业中类层面仍相对严重。统计分析表明,相似比较优势、国有资本比例过高带来的贸易壁垒以及地理区位等因素是京津冀区域内不同城市之间工业结构趋同的重要原因。

An Empirical Investigation of Structural Convergence in the Area of Beijing-Tianjin-Hebei

This paper investigates the convergence of industrial structure in the area of Beijing-Tianjin-Hebei using the data complied from the first economic census conducted at the end of 2004.Overall,there are some evidences to show the convergence of industrial structure in the area,but the evidences are weaker at the disaggregated industrial level.The convergence of industrial structure appears markedly in the region of Beijing-Tianjin-Langfang and Tangshan-Handan-Xingtai.The common industries are characterized by high profit margins with large market potential in Beijing-Tianjin-Langfang while the common industries mainly concentrate on resource-based industries in Tangshan-Handan-Xingtai.Statistical results suggest that similar comparative advantages,trade barriers coming from decentralization,and the neighboring location are the important reasons which lead to the convergence of industrial structure in the area of Beijing-Tianjin-Hebei while globalization and economic development level play a very marginal role.
