政府采购能够促进企业技术创新吗?——来自国家高新产业园的实证检验

Can Government Procurement Promote Enterprise Technological Innovation?——An Empirical Test about the National High-tech Zone

本文以上市公司为样本,探讨了国家高新区和政府采购政策组合对企业技术创新的共同影响。研究发现,国家高新区和政府采购政策组合对企业技术创新数量和质量具有显著激励作用,且"成熟期"的国家高新区和政府采购政策组合的正向影响更明显,但国家高新区和政府采购政策组合对高质量的企业技术创新并无显著的溢出效应。机制检验表明,国家高新区和政府采购政策组合通过缓解融资约束、增加税收优惠等机制促进企业技术创新。本文扩展了公共政策与企业创新的研究领域,丰富了国家高新区和政府采购政策组合的经济后果的文献,并为中国实施创新驱动战略和经济高质量发展提供了有益的政策参考。

This paper takes listed companies as a sample to explore the joint influence of national high-tech zone and government procurement policy portfolio on enterprise technology innovation.The study found that the national high-tech zone and government procurement policy portfolio have a significant incentive effect on the quantity and quality of enterprise technology innovation,and the positive impact of the"mature period"of the national high-tech zone and the government procurement policy portfolio is more obvious,but the national high-tech zone and government procurement policy portfolio has no significant spillover effect on high-quality enterprise technology innovation.The mechanism test shows that the national high-tech zone and the government procurement policy portfolio promote technological innovation by mitigating financing constraints and increasing tax incentives.This paper expands the research fields of public policy and enterprise innovation,enriches the literature on the economic consequences of the national high-tech zone and government procurement policy portfolio,and provides a useful policy reference for China to implement innovation-driven strategies and high-quality economic development.
