摘　　要：本文利用DEA模型、层次分析法和耦合度模型分析了1980-2010年长江三角洲16个地级市的城市化效率、经济发展水平,以及城市化效率与经济发展水平的耦合度,并对其耦合关系进行了理论初探,提出了概念模型。结果表明:①30年间,长三角城市化效率与经济发展水平的耦合度总体经历了缓慢上升—急剧上升—缓慢下降—急剧下降的过程,呈倒"U"型发展;②不同发展阶段的经济发展水平和城市化效率耦合关系不同,在一定时期,提高城市化效率可以提升区域经济发展水平,区域经济水平的发展也可提高城市化效率;但当城市化效率和经济发展达到一定的水平时,城市化效率的提高不再成为提升区域经济发展水平的重要因素,而区域经济发展水平的提升也不会过多地影响城市化效率;③城市化效率与经济发展水平存在动态耦合关系,经济发展水平较高的城市会首先摆脱城市化效率带来的促进作用。This paper used the DEA model,analytic hierarchy process and a model for coupling degree to analyze urbanization efficiency,economic development level,and the coupling relationship between the two for the 16 cities in the Yangtze River Delta from 1980 to 2010.As a result,theoretical exploration was conducted and a conceptual model was proposed.The results showed that：（1） During the 30 years of evolution,the economic development level in the Yangtze River Delta has been in a upward trend;regional development reached a balanced stage,and the coupling relationship between urbanization efficiency and economic development level exhibited an overall inverted ＂U＂： shaped pattern of ＂slow rise-sharp rise-slow decline-sharp decline＂.（2） In different developmental stages,economic development level had different relationship with urbanization efficiency.In a certain period of time,improvement of urbanization efficiency enhanced the regional economic development level,and vice versa.Once both reached a certain level,increase of urbanization efficiency is no longer an important factor to enhancement of the regional economic development level,and,again,vice versa.（3） There is a dynamic coupling relationship between urbanization efficiency and economic development level.Those cities with higher economic development level are the first to be independent of the effect of urbanization efficiency.
