摘　　要：将双循环理论引入两阶段技术创新过程,通过构建网络DEA模型测算2012-2020年中国区域技术创新内循环和外循环的阶段效率,结合SDM分析各影响因素对技术创新效率的溢出效应。计算结果表明:双循环视角下中国区域技术创新整体效率偏低,技术创新内循环效率高于外循环效率。内循环效率由东向西呈倒U型特征,外循环效率由东向西递减,且在2015-2017年政策过渡期后呈显著上升趋势。内循环效率在出口依存度上呈正向溢出效应,在进口依存度上呈负向溢出效应。外循环效率在社会经济资源丰度和出口依存度上呈现正向溢出,在外商直接投资上呈现负向溢出。研究结论为如何提升技术供给体系对国内需求的适配性提供理论支持和决策参考。The dual-cycle factors are introduced into the theoretical framework of technological innovation. The achievement transformation stage is subdivided into internal cycle stage and external cycle stage, which constructs a network DEA model to measure technological innovation efficiency. The SDM is used to analyze the spillover paths of influencing factors on technological innovation efficiency. The results indicate that the overall efficiency of regional technological innovation in China is low from the dual-cycle perspective, and the internal cycle efficiency is higher than external cycle efficiency. The internal-cycle efficiency shows an inverted U-shaped characteristic from east to west, and the external-cycle efficiency decreases from east to west, and shows a significant upward trend after the policy transition period of 2015-2017. The internal-cycle efficiency shows a positive spillover effect on export dependence and a negative spillover effect on import dependence. The external cycle efficiency shows positive spillover on socioeconomic resource abundance and export dependence, and negative spillover on foreign direct investment. The findings of the study provide theoretical support and decisionmaking reference for how to improve the suitability of the technology supply system for domestic demand.
