空间集聚与网络嵌入对技术创新的非线性影响

Non-linear effect of spatial agglomeration and network embedding on technology innovation

新一代信息技术产业面临技术与市场的双重不确定性,提升产业技术创新能力、激励企业开展技术创新成为理论界和实践界关注的焦点。以上海1966家云计算企业为样本,从地理空间集聚和社交网络嵌入两个维度,运用零膨胀负二项回归模型研究企业外部因素对技术创新的非线性影响。研究发现:空间集聚与企业技术创新间呈现U型关系,结合上海云计算产业城市空间分布情况可知,空间集聚对上海云计算创新的正向激励效应目前尚未显现;此外,以董事兼任构建公司社交网络,发现在环境不确定性较高的云计算市场,网络中心度对企业创新呈现一致性的正向影响。研究结论对云计算产业技术创新激励具有启示作用。

The new generation of information technology faces the dual uncertainty of technology and market. Enhancing industrial technology innovation and stimulating firms to carry out innovation-oriented strategy have attracted attention from both scholars and practitioners. Taking perspectives from spatial agglomeration and social network embedding, this research examines the non-linear effect of firms’ external factors on technology innovation. This research adopts zero expansion negative binomial regression model to analyze data sample coming from 1966 cloud-computing firms in Shanghai. Results suggest that spatial agglomeration and technology innovation show a U-shaped relationship. Combined with the spatial distribution of Shanghai cloud-computing industry, the positive incentive effect of spatial agglomeration has not yet taken its effect. This research develops firms’ social network based on concurrent directors. Analysis shows that the network centrality has a positive effect on technology innovation. Findings of this research have implications for government’s innovation policy and firms’ innovation strategy.
