摘要: 数字经济政策是政府推动数字经济发展与制造业企业创新的重要工具。利用中国2012—2018年数据的实证研究表明,数字经济政策适宜性供给显著促进了制造业企业创新,在经过一系列稳健性检验后,上述结论依然成立。数字经济政策适宜性供给的创新激励效应在高技术企业、中部地区企业以及非国有企业的样本中更显著。机制分析结果表明,数字经济政策适宜性供给通过促进分工深化、优化创新要素配置以及促进高端生产性服务业多样化集聚从而提升了制造业企业的创新水平;此外,数字经济政策适宜性供给对企业税负具有显著的抑制作用。这表明,企业新增创新投入的部分资金可能源于数字经济政策适宜性供给的减税降负效应。当数字经济发展水平达到一定阶段时,数字经济政策适宜性供给的创新激励效应显现,而“大水漫灌”式的数字经济政策供给对制造业企业创新呈现抑制效应。

Abstract: The digital economic policy is an important tool for the government to promote the development of the digital economy and the innovation of manufacturing enterprises. The empirical research based on China's 2012-2018 data shows that the suitable supply of the digital economic policy has significantly promoted the innovation of manufacturing enterprises. After a series of robustness tests, the above conclusions are still valid. The innovation incentive effect of the suitable supply of the digital economy policy is more significant in the samples of high-tech enterprises, enterprises in the central region and non-state-owned enterprises. The results of a mechanism analysis show that the suitable supply of digital economic policy can promote the innovation of manufacturing enterprises through the three paths: promoting the deepening of the division of labor, optimizing the allocation of innovation factors, and promoting the diversified aggregation of the high-end producer service industries. In addition, the suitable supply of digital economic policy has a significant inhibitory effect on corporate tax burdens, indicating that part of the company's new investment in innovation may be derived from the tax reduction effect of the suitable supply of digital economic policy. When the development level of digital economy reaches a certain stage, the innovation incentive effect of the suitable supply of digital economy policy appears, however, the“flooding”type of digital economy policy supply has a restraining effect on the innovation of manufacturing enterprises.

Key words: digital economic policy, corporate innovation, suitable supply
