服务业企业开展合作创新对其创新产出水平影响机理探究——创新信息获取渠道的中介作用

The Research on the Influence Mechanism of Cooperative Innovation of Service Enterprises on Their Innovation Output Level: The Meditating Effect of Innovative Information Access Channels

服务业企业开展合作创新提升其创新产出水平的机理部分在于拓宽创新信息获取渠道,即开展合作创新的服务业企业因能够从更多渠道获得创新信息而促进其创新产出水平提高。笔者以中关村海淀科技园服务业企业为研究样本,对接了2014年企业创新调查数据与第三次全国经济普查数据,采用多元线性回归方法、倾向得分匹配法及工具变量法检验服务业企业开展合作创新对包含产品创新、服务创新、流程创新在内的企业创新产出水平的影响,并进一步考察创新信息获取渠道数量在此影响过程中的中介效应。研究发现:服务业企业开展合作创新提升了企业自身的创新产出水平,且创新信息获取渠道数量增加部分中介了服务业企业开展合作创新对其创新产出水平的正向影响。本研究探讨了合作创新如何影响服务业企业创新产出水平,在理论上揭示出二者内在联系的机理,所得结论拓展了合作创新、创新信息来源的研究边际,为服务业企业通过合作创新提升创新产出水平提供了理论依据。

The mechanism for service enterprises to carry out cooperative innovation to improve their innovation output is to broaden the access to innovation information, that is, service enterprises carrying out cooperative innovation can obtain innovation information from more channels and further promote their innovation output.Taking the service enterprises in Zhongguancun, Haidian Science Park as the research sample, this paper matches the data of enterprise innovation survey in 2014 with the data of the third national economic census.We use multiple linear regression method, propensity score matching method and instrumental variable method to explore the impact of cooperative innovation of service enterprises on their innovation output including product innovation, service innovation and process innovation.We further test the meditating effect of the number of innovative information access channels.The research results show that the cooperative innovation of service enterprises improves their own innovation output, and the increase in the number of innovation information access channels partly mediates the positive impact of cooperative innovation on their innovation output.This study discusses how cooperative innovation affects the innovation output of service enterprises, and theoretically reveals the mechanism of the internal relationship between the two.The conclusions expand the research margin of cooperative innovation and innovation information sources, and provide a theoretical basis for service enterprises to improve the innovation output through cooperative innovation.
