中文摘要：

构建了大中型工业企业技术创新能力的评价指标体系，借助spss软件对我国31个省区的客观数据进行因子分析，提取出影响其技术创新能力的三个因子：技术创新效率因子、技术创新扩散因子、技术引进消化吸收因子，并得出结论：我国各区域大中型工业企业技术创新能力强弱不同；我国各省份大中型工业企业在技术创新效率、技术创新扩散、技术引进消化吸收三个方面的发展呈现不均衡状态；我国各省份大中型工业企业技术引进消化吸收严重不足。此研究为提高我国各省区的大中型工业企业技术创新能力提供了决策依据。

英文摘要：

This paper constructs the technological innovation ability evaluation index system of the large and medium - sized industrial enterprise, uses the SPSS software to analyze the objective data of 31 provinces and extracts three factors： technological innovation efficiency factor, technological innovation diffusion factor, and factor of technological import, di- gestion and absorption. It draws the conclusions ： （1）teehnological innovation ability of the large and medium - sized indus- trial enterprises is different; （2）large and medium -sized industrial enterprise＇development on technological innovation effi- ciency, technological innovation diffusion, technology import, digestion and absorption is unbalanced ; （3）large and medium - sized industrial enterprise＇ technology digestion and absorption is seriously insufficient. The research can provide deci- sion - making basis for imnroving the technological innovation ability of large and medium - sized industrial enterprise.
