长江经济带高质量发展需要经济效率的全面提升,而精准的效率测度有利于把握经济发展中出现的问题。运用三阶段DEA研究方法,修正外部环境因素与随机误差项等因素的干扰,对2012-2016年间长江经济带12个中心城市经济效率进行实证分析,结果发现:长江经济带中心城市经济非效率是由纯技术效率和规模效率走低共同导致的,但总体上规模效率的影响大于纯技术效率,环境因素的影响程度减弱;产业结构升级、地理环境对经济效率有正的影响,而城镇化、经济开放度、城乡差距不利于经济效率的提高;长江经济带中心城市效率值从下游至上游呈梯度递减。因此,要在提高投入规模基础上推进技术进步,继续优化资源配置减少投入冗余,以"一盘棋"战略思维统筹长江经济带发展。

The high-quality development of the Yangtze River Economic Belt requires an overall improvement in economic efficiency, and accurate efficiency measures are conducive to grasping the problems arising in economic development. Using the three-stage DEA research method, this paper analyzes the economic efficiency of 12 central cities in the Yangtze River Economic Belt from 2012 to 2016, and corrects the interference of external environmental factors and random error terms. The results found that: The economic inefficiency in the Yangtze River Economic Zone is caused by the combination of pure technical efficiency and scale efficiency, but the overall scale efficiency is greater than the pure technical efficiency; The development of industrial structure and geographical environment have a positive impact on economic efficiency, while urbanization, economic openness, and urban-rural disparity are not conducive to economic efficiency; The efficiency value of the central city of the Yangtze River Economic Belt is gradually decreasing from downstream to upstream. Therefore, it is necessary to increase the scale of investment on the basis of advancing technological progress, narrow the gap between urban and rural development in the process of promoting new urbanization, and coordinate the development of the Yangtze River Economic Belt with the strategic thinking of"one chess game.
