摘　　要：智能制造是我国制造业转型升级的主攻方向,而如何准确客观评价智能制造的实施效果成为亟待解决的问题。从技术创新投入视角,将智能制造试点政策实施视为一次准自然实验,采用2011-2019年制造业上市企业面板数据,通过PSM-DID方法研究智能制造对企业技术创新投入的影响。研究结果表明,智能制造显著影响企业技术创新投入,即通过提升客户集成度、供应商集成度进而提高企业技术创新投入,且促进作用仅发生在民营企业和非高新技术行业中。该发现扩展了现有研究外延,同时,为解决当前国际困局和促进智能制造的持续推广提供了重要实践价值。Intelligent manufacturing is the main direction of China's manufacturing transformation and upgrading,and how to accurately and objectively evaluate theimplementation effect of intelligent manufacturing has become an urgent problem to be solved.In this paper,from the perspective of technological innovation investment,the implementation of intelligent manufacturing pilot policy is regarded as a quasi-natural experiment.Based on the panel data of listed manufacturing enterprises from 2011 to 2019,the influence of intelligent manufacturing on technological innovation investment of enterprises is studied by PSM-DID method.The results show that intelligent manufacturing significantly improves the technological innovation investment of enterprises,and the robustness of this conclusion is verified by a series of methods.Intelligent manufacturing improves the technological innovation investment of enterprises by enhancing the integration of customers and suppliers.Heterogeneity research shows that the promotion of intelligent manufacturing to technological innovation investment is only verified in private enterprises and non-high-tech industries.This research expands the extension of existing research,and provides important practical value for solving the current international dilemma and the continuous promotion of intelligent manufacturing.
