摘要
创新政策试点是增强微观企业创新活力、贯彻落实国家创新驱动发展战略、助推经济高质量发展的重要举措。以国家自主创新示范区创新政策试点为准自然实验,基于对2007—2019年中国A股上市公司及地级市数据的匹配,采用双重差分模型考察了国家自主创新示范区创新政策试点对企业创新的影响机理。研究发现,创新政策试点有利于促进企业创新投入和创新产出增加;区分专利类型的检验结果表明,创新政策试点提高了企业实质性创新产出,对策略性创新产出影响不显著,即创新质量显著提升。进一步地,创新政策试点可通过加强政策激励、促进良性市场竞争、增加企业管理交易成本、降低资本市场交易成本等促进企业增加创新投入、提高创新产出。异质性检验发现:经济发展水平和要素市场发育程度越高的城市,创新政策试点对企业创新的促进效应越明显;相比于国有企业,创新政策试点对非国有企业创新的促进作用更明显;分企业生命周期阶段来看,创新政策试点对成长期与成熟期企业创新的促进作用较为明显。研究结论对于转变创新政策试点未来发展定位,提升国家自主创新示范区建设质量,激励企业创新,具有重要政策启示。
The innovation policy pilot is an important measure to enhance the innovation vitality of micro-enterprises,implement the national innovation-driven development strategy,and boost high-quality economic development.Based on the data matching of A-share listed companies and prefecture-level cities in China from 2007 to 2019,this paper takes the national independent innovation demonstration zone as a natural experiment and empirically tests the impact and mechanism of the innovation policy pilot on enterprise innovation by using the difference-in-differences model.The research shows that the innovation policy pilot significantly promotes the innovation input and output of enterprises.After distinguishing patent types,it is found that the innovation policy pilot mainly promotes the substantial innovation output of enterprises,while the impact on the strategic innovation output of enterprises is not obvious.In other words,the innovation quality of enterprises is significantly improved.Furthermore,the innovation policy pilot encourages enterprises to increase innovation input and improve innovation output by strengthening policy incentives,promoting benign market competition,increasing the transaction costs of enterprise management and reducing the transaction costs of the capital market.The results of the heterogeneity test are as follows.The higher the level of economic development and factor market development,the more obvious the promoting effect of the innovation policy pilot on enterprise innovation.Compared with state-owned enterprises,the innovation policy pilot plays an obvious role in promoting innovation in non-state-owned enterprises.From the perspective of life cycle stage,the innovation policy pilot has an obvious promoting effect on the innovation of enterprises in their growth and maturity stage.The research’s conclusion has important policy implications for changing the future development orientation of the innovation policy pilot,improving the construction quality of national independent innovation demonstration zones,and encouraging enterprise innovation.
