本文采用偏离-份额法分析了河南省县域经济产业结构变动趋势。研究发现:1工业增长较快的县域产业结构偏离分量和竞争力分量相对较高,和全省产业变动趋势相同,表现出较强的产业结构竞争力;2县域产业结构及其竞争力变化大。在宏观经济快速增长的背景下,传统农业县产业结构容易由第一产业为主向第二、第三产业为主转变,但发展到一定程度后产业结构很难有质的突破,竞争力下降,而对于工业化较早的县域,产业结构未能持续升级,竞争力很难维持。而依靠旅游、特色农业和矿产资源开发的新兴县域产业结构表现出较强竞争力。3探索出河南产业结构竞争力空间“热点”和“冷点”。少数产业结构竞争力上升县域和下降县域分别在豫西地区、豫西北地区集中连片分布,而多数县域产业结构竞争力不变并集中分布在豫东平原地区,呈现出空间相关性。县域产业结构多样化增加,在全省工业化加快趋势下,工业发展较快的县域产业结构更容易表现出较强的竞争力,同样,农业发展形成的产业特色也可以增强产业竞争力。
In this paper, deviation-share method is used to analyze the changing trend of county economic structure in Henan Province. The results show that: 1 The deviation of industrial structure in the county with relatively rapid industrial growth is relatively high, and the trend of industrial changes in the province is the same, showing a strong competitiveness in industrial structure; 2 The industrial structure and competitiveness of counties vary greatly . In the context of rapid macroeconomic growth, the industrial structure in traditional agricultural counties tends to shift mainly from the primary industry to the secondary and tertiary industries, but it is hard to have a qualitative breakthrough in the industrial structure after development to a certain extent, resulting in a decline in competitiveness , While for the earlier industrialized counties, the industrial structure failed to escalate and its competitiveness was hard to maintain. However, the emerging county industrial structure relying on the development of tourism, special agriculture and mineral resources has shown comparatively strong competitiveness. 3 to explore the competitiveness of Henan industrial structure “hot spot ” and “cold spot ”. The competitiveness of a few industrial structures increased in the counties and descend counties in the western Henan and northwestern areas, respectively. However, the competitiveness of most industrial counties in the counties remained unchanged and concentrated in the plain areas of eastern Henan Province, showing a spatial correlation. With the diversification of industrial structure in counties, under the accelerating industrialization in the province, the industrial structure in the county with faster industrial development is more likely to show stronger competitiveness. Similarly, the industrial features formed by agricultural development can also enhance the industrial competitiveness.
