中文摘要：

本文从技术生态的视角，选取20个指标拟合构建高技术产业技术生态位评价体系，采用主成分分析和区域空间多维结构模型．对中国高技术产业技术生态位“宽度”和“深度”进行测评并进行了深入剖析。结果显示：区域高技术产业技术生态位宽度拓展创新水平和发展深度均呈现出由东部地区向中、西部地区依次递减的分布态势，且各区域内部存在明显差异。同时，技术生态位成长环境空间分布差异明显，不平衡状态相当严重．高技术产业投入与产出效率、技术创新生态系统适应度呈现出正相关关系。

英文摘要：

From the ecological perspective of technology, the paper selected 20 targets fitting to construct the high-tech industry technology＇s ecological niche appraisal system. It used the principal components analysis and the regional space multi-dimensional struc- tural model to assess high-teeh industry technology ecology position＇s ＂width＂ and ＂depth＂ of China, and carried on the thorough anal- ysis. The results shows that width innovation level of regional high-tech industry technology＇s ecology niche and depth of development are appearing in decreasing in turn from the East to Midwest areas. Within various regions interior, there exists significant differ- ence. Environment space distributions of technology＇s ecological niche are difference： Imbalance is serious; High-tech industry input and output efficiency, technological innovation eco-system are showing a positive correlation.
