医药制造高技术产业时空演化研究

Spatial and temporal dynamics of medical and pharmaceutical products manufacturing of China

采用我国医药制造高技术产业主营业务收入,运用信息熵、行业集中度、Theil熵、空间集中度和空间自相关等方法研究了我国2000—2013年医药制造高技术产业的时空演化规律。研究结果表明,在时间序列上全国医药制造高技术产业演化可以大致划分为3个阶段,即"均衡→不均衡→均衡"的过程,医药制造高技术产业主要集中在化学药品制造和中成药生产两个行业,主营业务总收入超过了整个医药制造业的85%;在空间上,全国医药制造高技术产业呈现较强的地理集中现象,主要分布在山东、江苏、浙江和河北等省,形成了长三角和环渤海医药制造高技术产业聚集区,这种地域分化的现象具有显著的空间正相关性。

Based on the revenue from principal business of medical and pharmaceutical products manufacturing in 31 spatial units,this paper analyzes the spatial and temporal dynamics of medical and pharmaceutical products manufacturing in China from 2000 to 2013 by using information entropy,concentration ratio,Theil index,spatial concentration ratio and Local Moran I index.The results indicate that from time dimension,the pharmaceutical industry evolution in China can be divided into three stages with the character of＂balance→unbalance→balance＂,and medical and pharmaceutical products manufacturing is mainly chemical medicine and production of finished traditional Chinese herbal medicine.Moreover,revenue from principal business accounts for more than85% of the medical and pharmaceutical products manufacturing.From the space dimension,the pharmaceutical industry of China is geographically concentrated mainly in Yangtze River delta and Bohai bay,including Shandong Province,Jiangsu Province,Zhejiang Province,Hebei Province and so on.The phenomenon of regional differentiation has a significantly positive correlation.
