本研究通过面板数据分析，考察了创新过程中的研发和信息通信技术，以及这两者是如何相互结合进行创新的。这些调查是在2012年2月和2017年3月进行的。将创新数量作为结果变量，通过因子分析从相关问题中提取与R&D和信息通信技术相关的解释变量。由于误差项可能包含异方差，估计了带有辅助变量的固定效应稳健模型。研发自主性和研发自主性与信息通信技术的交叉项显著，表明信息通信技术通过研发自主对创新做出贡献。
This study examines R&D and information and communication technologies (ICTs) in the innovation process, and how these two are integrated with each other for innovation by panel data analysis. The surveys were conducted in February 2012 and March 2017. The number of innovations is taken as an outcome variable, while explanatory variables related to R&D and ICTs were extracted from related questions by factor analysis. The fixed effect robust model with an instrumental variable is estimated, since the error term may contain heteroscedasticity. R&D autonomy and the cross-term of R&D autonomy and ICTs are significant, indicating that ICTs contribute to innovation via R&D autonomy.
