基于省际面板数据,采用区位产值指数、地区专业化指数及空间分离指数,并把2001-2010这10年分成2001-2004、2004-2007及2007-2010三个时间段,分析了中国医药制造业的区域差异和空间集聚状况。研究结果表明,东部地区总体的专业化水平高于西部地区低于中部地区,而且各地区间的专业化水平差异较大,尤其是东部各省市与中西部的比较;另外,地区专业化水平在三个时段呈现“低-高-低”的特点,十年间整个医药制造业的空间集聚程度也表现出“扩散-集聚-扩散”的规律。最后,给出了相应的政策建议。
Based on the inter-provincial panel data, using the locational output value index, regional specialization index and spatial separation index, furthermore dividing 2001-2010 decade into 2001-2004, 2004-2007 and 2007- 2010 periods, this paper analyzes the regional differences and spatial concentration state of China's pharmaceutical manufacturing Industry. The results show that the overall specialization level of the eastern region is higher than that in the western region, which is lower than middle region and that specialization level differs across regions, especially the comparison of the eastern provinces and the Midwest. Besides, the level of regional specialization in the three periods shows the characteristics of "low-high-low", and the degree of spatial aggregation of China's pharmaceutical manufacturing industry, which also shows the law of "diffusion-gathering-diffusion". This paper finally summarizes the conclusion and makes the corresponding policy suggestions.
