目的：探索医药制造业创新能力在空间分布中的规律及价值。方法：基于空间计量分析原理，选取2010年的研发人员全时当量和研发经费内部支出作为解释变量，2010-2013年的新产品销售收入作为被解释变量，运用普通计量回归模型（OLS）、空间计量回归模型（空间滞后模型和空间误差模型），应用GeoDa和R软件，对中国医药制造业的研发投入与产出关系进行了研究。结果：医药制造业创新投入产出滞后1年，医药制造业各区域创新能力的全局Moran’s I系数有统计学意义；区域显示上海、江苏存在较高的创新能力和集聚效应，安徽、福建、黑龙江等空间相关性不强。结论：针对不同的区域选择性地加强研发经费的投入，充分发挥高创新能力省区的知识溢出效应，促进技术创新能力不足的省区发展，从而提高我国医药制造业创新能力。
目的：探索醫藥製造業創新能力在空間分佈中的規律及價值。方法：基于空間計量分析原理，選取2010年的研髮人員全時噹量和研髮經費內部支齣作為解釋變量，2010-2013年的新產品銷售收入作為被解釋變量，運用普通計量迴歸模型（OLS）、空間計量迴歸模型（空間滯後模型和空間誤差模型），應用GeoDa和R軟件，對中國醫藥製造業的研髮投入與產齣關繫進行瞭研究。結果：醫藥製造業創新投入產齣滯後1年，醫藥製造業各區域創新能力的全跼Moran’s I繫數有統計學意義；區域顯示上海、江囌存在較高的創新能力和集聚效應，安徽、福建、黑龍江等空間相關性不彊。結論：針對不同的區域選擇性地加彊研髮經費的投入，充分髮揮高創新能力省區的知識溢齣效應，促進技術創新能力不足的省區髮展，從而提高我國醫藥製造業創新能力。

Objective: To explore the law and value of the innovation ability of pharmaceutical industry in spatial distribution.Methods: Based on the principle of spatial econometric analysis, full-time equivalent (FTE) of R&D personnel and R&D internal expenditure in 2010 were selected as explaining variables, and the revenues for the sales of new products during 2010-2013 were taken as explanatory variables. The relationship between R & D input and output in Chinese pharmaceutical industry was investigated by using the common regression model (OLS), the spatial econometric regression model (model and spatial error model of spatial lag) and applying GeoDa and R software.Results: There was 1 year lag between the input and output in pharmaceutical industry innovation and statistical signiifcance in the global Moran I of ‘regional innovation of pharmaceutical industry. Region analysis showed that Shanghai and Jiangsu had a high innovation ability and the agglomeration effect while the spatial correlation in Anhui, Fujian, Heilongjiang and the others was not strong.Conclusion: The input of R&D expenditures should be selectively strengthened and the effects of knowledge spillover in those provinces and regions with high innovation ability should be fully played so as to promote the development of province and regions with insufifcient technology innovation and improve the innovation level of Chinese pharmaceutical industry.
