基于区位熵的区际产业分工模式研究——以东北三省为例

Research on the Industrial Division Mode Based on the Location Quotient——the Erample of Three Northeast Provinces of China

产业分工包括部门间分工、部门内分工和产业链分工。通过三次产业结构比较发现,东北三省存在产业结构趋同现象,但这并不必然意味着区际分工和专业化程度的弱化。本文通过区位熵和自定义的区位熵比值两个指标度量了东北三省27个工业行业专业化程度,发现东北三省产业结构存在"大同小异"。尽管三次产业结构趋同,但在第二产业内部各细分行业存在明显差异,表明东北三省部门间分工在弱化,而部门内分工和产业链分工在强化。为推进产业分工合作,本文研究了东北三省适合参与区际分工的重点行业,并给出了具体的政策建议。

The industrial division includes interdepartmental division, intradepartmental division and in- dustrial -chain division. By analyzing the three industrial structures, the convergence of industrial structures is found in three northeast provinces. But it does not mean that the inter - regional division of labor and the degree of specialization are weakened. In this paper, the specialization degree of 27 industries in the three northeast provinces is measured by location quotient and the ratio of location quotient. The study found that the three northeast provinces have similar industrial structures, but there are significant differences within the sub - sectors of the secondary industry. The interdepartmental division of the three northeast provinces is weak- ened, but intradepartmental division and industrial -chain division are strengthened. In order to promote the cooperation of industrial division, we study the key industries which are appropriate for the inter - regional di- vision in the three northeastern provinces and give specific policy proposals.
