中文摘要：

通过因子分析法对各项指标进行浓缩的基础上，运用动态分布滞后模型、误差修正模型、脉冲响应和预测方差分解等方法进行了实证分析。结果显示，二者存在耦合关系，技术创新态势稳定，但高技术产业高端化的波动幅度较大。提出了优化高技术产业高端化与技术创新耦合关系的对策建议。

英文摘要：

This paper abstracted the main variables of high-tech industry achieving high-end and technological innovation with factor analysis method .Empirically analyzed the degree of coupling and deviation with dynamic distributed lag model , error correction model and variance decomposition methods .The results show that there exist the coupling relations between them, technology innovation is stable , but the volatility of high-tech industries achieving high-end is larger .
