基于熵的多样化指数显示生物医药产业集聚趋势不断加强。以产值份额为变量构建空间变系数面板模型，研究29省生物医药产业竞合关系。结果显示：空间变系数面板模型能较好检验区域产业竞合关系；相邻效应显示，10个省生物医药产业显示为对周边省份竞争效应，11个省生物医药产业显示为对周边省份合作效应，8个省生物医药产业与周边省竞合净效应不显著。整体效应显示，9个省竞争力较强，12个省竞争力弱，8个省处于中等。

Using the entropy - based diversity index , this paper finds that competition in bio pharmaceutical industry becomes to strengthen .Using output ratio for the variable ,it applys spatial panel data models for studying the competition and cooperation of the bio pharmaceutical industry between 29 provinces for the first time . Results : spatial panel data models can be applied to study the competition and cooperation of regional industries ; adjacent effect shows that 10 provinces' bio pharmaceutical industries show competitive effect on the surrounding provinces ,11 provinces' bio pharmaceutical industries show cooperative effect on the surrounding provinces ,and 8 provinces' bio pharmaceutical industries' competition and cooperation effect on the surrounding provinces are not significant .The overall effect shows strong competitiveness in 9 provinces ,12 provinces' bio pharmaceutical industries' competitiveness are weak , and 8 provinces are in the middle .
