辽宁省制造业及其关联行业集聚格局与效应分析

制造业及其关联行业的空间集聚对区域竞争力的提升、区域经济空间格局的塑造具有重要的意义。基于产业集聚测度指标、改进引力模型及投入产出分析,对辽宁省制造业及其关联行业的空间集聚格局及其空间经济效应进行评价,并与全国进行对比。研究发现：辽宁省制造业以资源及资本密集型行业专业化优势最明显,但1995—2016年间在全国内的比较优势整体上有所减弱;制造业的关联行业个数小于国民经济各行业的平均值,辽宁省制造业关联行业拓展空间较大;沈阳、大连与鞍山是全省制造业空间分布以及制造业产业链空间联系的中心城市,但多数制造业行业与其关联行业的共同集聚特征并不明显;经济效应方面,2002—2012年间辽宁省的制造业对全国国民经济的推动效应有所减弱,制造业产业链对国民经济的拉动作用有较大提升空间。

The cluster pattern and effect analysis of Liaoning manufacturing industry and its related industries

The spatial agglomeration of manufacturing industry and its related industries is of great significance to the improvement of regional competitiveness and the shaping of regional economic spatial pattern. Based on industrial agglomeration measure index, modified gravity model and the input-output analysis, this article evaluated the spatial agglomeration pattern and spatial economy effect of the manufacturing industry and its related industries in Liaoning, and made comparsion with the whole country. The following conclusions can be drawn: Liaoning is most prominent in resources and capital intensive manufacturing industries, but during 1995-2016, the comparative advantage of Liaoning manufacturing industries in the national scale decreased; the number of related industries in manufacturing is smaller than the average of all industries in the national economy, the related industries of manufacturing in this province had a great potential of development; Shenyang, Dalian and Anshan are central cities of spatial distribution on manufacturing industry and spatial connection of manufacturing industry chain.As for most of manufacturing industries, the common agglomeration characteristics with their related industries are not obvious; in terms of economic effect, the driving effects of Liaoning manufacturing on the national economy weakened during 2002-2012, the pulling effect of manufacturing industry chain on the national economy had a large expansion space.
