贸易自由化对异质性企业技术创新的影响研究

基于新异质性贸易理论，分析贸易自由化与异质性特征对企业资源配置和创新效应的影响。结果表明：贸易自由化可通过技术溢出效应、市场效应影响企业技术创新，提升我国工业企业的创新能力。同时考虑企业内外部异质性，发现贸易自由化与不同属性的企业的技术创新能力有密切关系，东部地区大型国有企业存在显著技术溢出创新提升。鉴于此，应充分结合贸易自由化对异质性企业的影响效应，提高企业的生产率和降低进入壁垒，优化市场结构。

Research on the Impact of Trade Liberalization on Heterogeneous Enterprise Technological Innovation

This paper explores the impact of trade liberalization and the heterogeneous characteristics on resource allocation and innovation within enterprises in line with the new heterogeneous trade theory. The results show that trade liberalization can affect enterprise technological innovation through technology spill-over effects and market effects, and enhance the innovation performance of industrial enterprises in China. Based on the internal and external heterogeneity of enterprises, it is found that there is a close relationship between trade liberalization and enterprises’ technological innovation performance. Large state-owned enterprises in the eastern region benefit from technology spill-over effects and have significant technological innovation improvements. In view of this, it is necessary to fully consider the impact of trade liberalization on heterogeneous enterprises, improve enterprise productivity, reduce entry barriers, and optimize market structure.
