本文基于我国30个省市2002-2015年的面板数据，探究了产学研合作、国内技术购买、国外技术引进三种知识获取方式对区域创新能力的影响，以及吸收能力在其中的中介作用。研究发现：从各省市看，产学研合作、国内技术购买、国外技术引进这三种知识获取方式对区域创新能力均具有显著的正向影响；吸收能力在产学研合作、国内技术购买对区域创新能力的影响关系中均具有部分中介作用，在国外技术引进对区域创新能力的影响关系中具有完全中介作用。从各省市组群看，各知识获取变量对区域创新能力的影响存在差异；中创新能力省市组群中的吸收能力在产学研合作、国内技术购买与区域创新能力之间均具有部分中介作用，而高、低创新能力省市组群中的吸收能力在各知识获取变量与区域创新能力之间均不存在中介作用。最后，有针对性地提出了相关的策略建议。

Based on the panel data of 30 provinces in China from 2002 to 2015, this paper explores the impact of three ways of knowledge acquisition, including the industry-university-research collaboration, the purchase of domestic technology and the import of foreign technology, on regional innovation capacity, and the mediating role of absorptive capacity. We have found that, viewing from all the provinces, all the three ways of knowledge acquisition significantly and positively affect regional innovation capability, and absorptive capacity has a partial mediating role in the relationship between both of the industry-university-research collaboration and the purchase of domestic technology and regional innovation capacity, and has a fully mediating role in the relationship between the import of foreign technology and regional innovation ability. For the groups of provinces and cities, the impact of the three ways of knowledge acquisition on regional innovation ability are different; absorptive capacity has a partial mediating role between both of the industry-university-research collaboration and the purchase of domestic technology and regional innovation capacity in the groups of provinces and cities with medium innovation capacity, while has no mediating effect between all ways of knowledge acquisition and regional innovation capacity in the groups of provinces and cities with high and low innovation capacity. Finally, this paper puts forward the relevant strategies and suggestions.
