通过构建长江经济带科技创新驱动力指标评价体系，并基于AHP-EVM模型设置主客观综合指标权重，得到科技创新驱动力综合指标，科技创新投入、科技创新载体、科技创新产出、科技创新绩效4个一级指标，以及10个二级指标得分，全面系统地评价了长江经济带110个城市的科技创新驱动力状况。结果表明，以上海、南京、武汉、苏州、杭州等城市为长江经济带科技创新核心驱动力的格局已趋于稳定，成都、重庆、南昌、贵阳等中西部中心城市的排名均有所提升。
By constructing the evaluation system of the scientific and technological innovation driving force index（S&T IDFI）in the Yangtze River Economic Belt，and setting the weight of the subjective-objective comprehensive index based on the AHP-EVM model，this paper obtain the comprehensive index of the S&T IDFI，the input of S&T innovation，the carrier of S&T innovation，the output of S&T innovation，the performance of S&T innovation，and the score of 10 secondary indicators，and comprehensively and systematically evaluate the S&T IDFI in 110 cities of the Yangtze Economic Belt. The results show that the pattern of Shanghai，Nanjing，Wuhan，Suzhou，Hangzhou and other cities as the S&T innovation hubs in the Yangtze River Economic Belt has stabilized，and the ranking of central cities in the central and western regions such as Chengdu，Chongqing，Nanchang and Guiyang has been improved.
