数字经济、空间溢出效应与区域创新效率

在经济高质量发展的现实需求下，如何进一步提升区域创新效率对中国加快建设成为社会主义现代化强国具有重要意义。为探究数字经济发展对创新效率的促进作用，本文以中国大陆分地区面板数据为研究对象，采用面板熵值法和随机前沿方法，分别测算了数字经济发展水平与区域创新效率，并运用空间计量模型实证检验了数字经济发展能否通过知识溢出效应促进区域创新效率的提升。研究发现，中国的数字经济发展显著提高了区域创新效率，并且数字经济通过空间溢出效应带动了其他地区创新效率的提升。在考虑了不同的空间距离权重矩阵后，这一结果依然稳健。本文相关结论为充分有效地利用数字经济发展的空间溢出效应，进而促进中国区域创新效率的提高提供政策启示。

Digital Economy, Spatial Spillover Effect and Regional Innovation Efficiency

Under the realistic demand of high-quality economic development, how to further improve regional innovation efficiency is of great significance for China to accelerate its construction into a powerful modern socialist country. Based on the panel data of the provincial area in mainland China, this paper uses the method of spatial econometric analysis to observe whether digital economy can promote regional innovation efficiency through spatial knowledge spillover, after measuring the development level of digital economy and regional innovation efficiency by adopting panel entropy method and stochastic frontier analysis respectively. The research indicates that the development of digital economy in China can promote the increase of regional innovation efficiency obviously, and also leads to the improvement of innovation efficiency in other regions through spatial spillover effect. The results are still robust based on considering different spatial weight matrices. The conclusion of this paper provides policy inspiration for making full use of the spatial spillover effects of digital economy and promoting the overall improvement of regional innovation efficiency.
