环渤海地区产业结构趋同的实证研究

利用产业结构相似系数，从三次产业结构、工业内部结构以及主要工业产品三个不同的层面上对环渤海地区“三省两市”的产业结构进行实证分析之后发现，环渤海地区的省市间只在三次产业机构这样的宏观层面上具有较高的相似系数，而在工业内部以及主要工业产品上相似水平大大降低。因此环渤海地区产业结构间只有一定程度的趋同。不存在严重的产业同构现象，并且这种趋同现象有其内在的必然性。

The Authentic Research on the Industry Structure Convergence In the Bohai Rim Region

After doing the authentic research by using the industry structure similarity coefficient from three industry structure,industry internal structure and the main product three different levels to the industry structure of the "three provinces and two cities in the Bohai Rim region,we can find the provinces and cities in the Bohai Rim region have high similarity coefficient in the macro-level of three industry structure,while have low similar level in the inner part of industry and the main industry product.So the industry structures in the Bohai Rim region only nave a little convergence,not existing serious industry convergence,and the convergence has its inherent certainty.
