| 摘 要： | 准确把握专利密集型产业的空间集聚特征及演化趋势,可以为产业合理布局和制定产业政策提供科学依据。本文采用Theil熵、地区集中度、空间自相关检验以及标准差椭圆方法,对我国专利密集型产业的空间集聚特征及演化趋势进行了全面细致地考察。研究结果表明：我国专利密集型产业的集聚水平较高,其细分行业的集聚水平存在明显差异;空间集聚具有显著的正向相关性,集聚模式以高-高型和低-低型为主;区位分布呈东北—西南的空间分布格局,产业中心向西南方向偏移,集聚方向顺时针旋转,西南部地区对专利密集型产业的拉动作用逐渐增强。

The Spatial Agglomeration and Evolutional Trend of Patent-intensive Industries |
| |
| Abstract: | It can provide a scientific basis for rational industrial distribution and making industrial policies by in-depth understanding the spatial agglomeration characteristics and evolution trend of patent-intensive industries. This paper uses the Theil entropy, regional concentration degree, spatial autocorrelation test and standard deviational ellipse to conduct a comprehensive and detailed investigation on the spatial agglomeration characteristics and evolution trend of China"s patent intensive industries. The results show that the agglomeration level of China"s patent-intensive industries is relatively high and there are obvious differences among its subdivided industries. The spatial agglomeration of patent-intensive industries shows remarkable positive correlation, its patterns are mainly high-high type and low-low type. The location distribution presents a northeast-southwest spatial pattern, industrial center tends to shift to the southwest, and direction of the ellipse rotates clockwise. The driving effect of southwest region on patent-intensive industry is gradually strengthened. |
