摘　　要：基于城市投入产出指标,采用超效率DEA、Malmquist指数和耦合度分析法,对长江经济带110个城市的城市投入产出效率及其与生态环境的耦合关系进行研究,结果显示:1)2001年~2015年上海在城市资源要素投入产出效率方面明显优于其他城市.攀枝花、六盘水等一些工业城市的城市效率得分低于0.626.城市效率相对低的城市主要由川西北、皖南等地分布转移到川西南、鄂北等地区分布.2)从时空格局演变看,2001年~2015年间长江经济带城市的tfpch值平均每年提升0.8%.长江下游沿海地区城市和多数沿江城市的tfpch值要明显大于其他城市.3)攀枝花、马鞍山等资源型城市的生态环境得分最低,并且得分逐年下降,表明在资源开发时对当地的生态环境破坏较为严重.整体上,长江经济带城市的生态环境状况呈现先恶化后稳定的状态.4)从时空格局演变看,2001年~2015年长江经济带的城市投入产出与生态环境耦合协调性呈现先降低后升高的态势.低度耦合型城市由长江中下游的湘北、苏北等地区转移到鄂西北、湘南等地区.This paper calculated the input-output efficiency of 110 cities＇ of Yangtze River economic belt （YREB）, then evaluated the relationship between efficiency and ecotope by Super-efficiency DEA and Malmquist index and Coupling Analysis model, which based on the urban input-output indicators. Four major results were obtained. First, Shanghai＇s resources input-output efficiency eas superior to other cities from 2001 to 2015. The urban efficiency scores of some industrial cities such as Panzhihua and Li upanshui are lower than 0. 626. The distribution of lowest efficiency cities mainly transfered from the northwest of Sichuan and the south of Anhui Province to the southwest of Sichuan and the north of Hubei Province. Second, The tfpch of YREB was increased by 0.8% per year on average from the perspective of Spatiotemporal pattern evolution from 2001 to 2015. The tfpch values of coastal cities which lie in the lower reaches of Yangtze River and most of the cities along the Yangtze River were significantly greater than oth er cities. Third, the resource-based city such as Panzhihua and Maanshan had the lowest ecotope scores, and the scores declined year by year, which indicates that the ecotope has been damaged severely while developing the mineral resources. The ecotope of YREB emerge a deteriorating and stable trend as a whole. Fourth, The cities＇ coupling coordination between input-output and ecotope of the YREB descended first and then ascended on the perspective of Spatiotemporal pattern from 2001 to 2015. The low cou piing type cities transfered from the north of Hubei and north of Jiangsu area to the northwest of Hubei, Hunan and other regions which lie in the middle and the lower teaches Yangze River.
