区域间技术交易网络、吸收能力与区域创新产出——基于电子信息和生物医药领域的实证分析

Interregional technology transaction network,absorptive capacity and regional innovation output:Analysis based on the electronic information and biological medicine fields

借鉴社会网络理论中的濡染模型,将网络节点行为变量引入知识生产函数对模型进行扩展,基于扩展后的模型考察我国电子信息和生物医药领域的区域间技术交易网络、吸收能力与区域创新产出的关系。研究表明:(1)区域间知识溢出模式具有明显的技术领域特征,在电子信息领域,不同区域节点是通过模仿结构相似的竞争者的行为获取外部知识;在生物医药领域,不同区域节点是在互惠网络中获取新知识。(2)在不同技术领域,知识吸收能力对区域间技术交易网络与区域创新产出关系的调节作用存在差异。但是,吸收能力高的区域和吸收能力低的区域,都可以通过嵌入区域间技术交易网络,实现区域创新能力的提升。

Based on the contagion model of social network theory,using China's 31 provinces' technology market contracts of electronic information field and biological medicine field in 2006- 2010 as data,this paper expands the knowledge production function by introducing variables of network node behavior,then examines the influence of interregional technology transfer network on regional innovation output,and discusses the moderate effects of regional absorptive capacity,so as to reveal the relationship among interregional technology transfer network,knowledge absorptive capacity and regional innovation output. The results show that:( 1) There are differences of interregional knowledge spillovers in different technology fields,regions tend to acquire new knowledge through imitating the behavior of competitors with similar structure in electronic information field,while regions trend to acquire new knowledge in mutual cohesion network in biological medicine field.( 2) Knowledge absorptive capacity has different moderate effects on the relationship between interregional technology transfer network and regional innovation output in different technology fields; however,regions with high and low absorptive capacity can both achieve regional innovation capability through embedding into interregional technology transfer network.
