以柯布—道格拉斯函数为基础,利用区位熵系数构建模型,测算2005—2013年宁夏三次产业集聚对产出增长的贡献率。结果表明,宁夏三次产业集聚对产出增长具有正向的促进作用,但贡献度很小,都接近于0。因而得出以下结论:产业集聚有利于产出增长,产业集聚程度的增加可以提升产业集聚对产出增长的贡献率,但这种贡献率的大小更多的受到产业集聚程度动态变化过程的影响,而非某一个或某几个特定年份集聚程度的大小。
Based on Cobb-Douglas function, the model of location entropy coefficient was used to calculate the contribution rate of three industrial agglomerations to output growth in Ningxia in 2005-2013. The results show that the three industrial agglomerations in Ningxia have a positive effect on the output growth, but the contribution is small, all close to zero. Therefore, the following conclusions are drawn: industrial agglomeration is conducive to output growth, and the increase of industrial agglomeration can increase the contribution rate of industrial agglomeration to output growth. However, this contribution rate is more influenced by the dynamic process of industrial agglomeration , Rather than the size of one or a few specific years of concentration.
