山西省主要农作物产业集中度及产业布局研究

产业集中度是衡量一个产业在一个区域内的集中化生产程度的重要指标。用作物产量与县(小区)之间的关系可以定量地计算出更大区域中各产业集中度。通过对1991～2000年山西省小麦等16种粮食、经济作物的产业集中度及其变化的研究,小麦、大豆等8种作物集中度增加,布局趋于集中,玉米、高粱等8种农作物集中度减小,布局更加分散。进一步优化产业布局,需要运用产业集聚理论,培育16种作物产业集聚区。

On Concentration Level of Crops Production and Distribution of Shanxi Province

The production concentration is an important index to measure gathering level of an industry in certain area.The index can be calculated basing on relation between crop production and counties.16 species of crops such as wheat and so on in Shanxi province were measured initially. The production concentration of 8 species of crops such as wheat was increasing, and that of 8 species of crops such as corn was decreasing. In order to optimiye distribution of crop production, the gathering zones should be fostered to each crop in Shanxi.
