首先引入双寡头两阶段博弈模型,分析特定区域中企业创新网络与产业创新效率的联系,再以我国专利数据与省级面板数据为样本,综合运用随机前沿面分析方法与面板门槛方法,实证研究了我国企业创新网络对创新效率的门槛效应。研究结果表明:在产业创新效率较低的区域,区域内、区域间及区域整体企业创新网络的密集程度都对产业创新效率有抑制作用;在产业创新效率较高的区域,区域间企业创新网络的密集程度对产业创新效率有促进作用,而区域内、区域整体企业创新网络的密集程度与产业创新效率呈倒“U”型关系;区域内企业创新网络的密集程度比区域间高的地区拥有更高的产业创新效率。
Firstly, the duopoly two-stage game model is introduced to analyze the relationship between enterprise innovation network and industrial innovation efficiency in a specific region. Taking the patent data and provincial panel data in our country as samples, the random frontier analysis method and panel threshold method are used in the empirical study The threshold effect of innovation network in China’s enterprise innovation network. The results show that: in the regions with low efficiency of industrial innovation, the intensity of the whole enterprise innovation network in the region, region and region all have an inhibitory effect on the efficiency of industrial innovation; in the regions with higher industrial innovation efficiency, the inter-regional firm innovation network The intensity of the industrial innovation has a positive effect on the efficiency of industrial innovation. However, the intensity of the overall innovation network of enterprises in the region and the region is inversely related to the efficiency of industrial innovation. The intensity of the innovation network in enterprises in the region is higher than that in the region The region has a higher efficiency of industrial innovation.
