国家高新区对外贸易、高新技术企业占比影响创新效率的实证研究

加快推进国家高新区发展，是提高创新竞争力、实现经济高质量发展的重要途径。运用超效率DEA模型测算2013-2017年国家高新区创新效率，利用面板数据模型考察对外贸易、高新技术企业发展与创新效率的相关关系及地区差异。研究表明：我国东部地区国家高新区创新效率相对较高，中部地区、西部地区、东北地区高新区创新效率差异明显；国家高新区对外贸易、高新技术企业占比对高新区创新效率提升具有显著正向促进作用，且存在显著正向时滞效应；国家高新区对外贸易、高新技术企业占比对国家高新区创新效率的影响存在地区差异。新时代全面提升国家高新区创新效率，应以高新技术企业为主体，以进一步扩大开放为路径，注重开放贸易、高新技术企业发展相关政策的阶段性与针对性调整。

An Empirical Study on the Influence of Foreign Trade and High-tech Enterprises in National High-tech Zones on Innovation Efficiency

Accelerating the development of national high-tech zones is an important way to improve China's innovation competitiveness and achieve high-quality economic development.The ultra-efficient DEA model is used to measure the innovation efficiency of the national high-tech zone in 2013-2017, and the panel data model is used to examine the relationship and regional differences between foreign trade, high-tech enterprise development and innovation efficiency.The research shows that the innovation efficiency of the national high-tech zones in the eastern part of China is relatively high, and the innovation efficiency of the high-tech zones in the central, western and northeast regions is obviously different.The proportion of foreign trade and high-tech enterprises in the national high-tech zones is significant for the innovation efficiency of the high-tech zones.Positive promotion, and there is a significant positive time lag effect; the national high-tech zone foreign trade, high-tech enterprises accounted for the regional high-tech zone innovation efficiency has regional differences.In the new era, we should comprehensively improve the innovation efficiency of the national high-tech zones.We should take high-tech enterprises as the main body, further expand the opening up as a path, and pay attention to the phased and targeted adjustment of policies related to the development of open trade and high-tech enterprises.
