Abstract:

Based on referring to the concept and framework of capacity coupling in coupled wave theory,and from the four aspects of economic growth,economic structure and economic relationship,economic benefit,and economic sustainable development,as well as from the four aspects of income level,consumption level,education and health level,and dwelling level,this paper constructed the evaluation index system for the coupling coordination correlation between economic development and residents life,and introduced coupling degree function and coupling coordination degree function to research the coupling coordination relationship between the two subsystems,namely economic development and residents life,of the 16 prefecturelevel city units in the Yangtze River Delta during 2003-2010.The results show as follows.(1) The degree of coupling coordination between economic development and the quality of residents life of each city in the Yangtze River Delta region covered six grades from Type I to Type VI,and any city in this region maintained a relatively stable coupling coordination degree in the 8 years.But in terms of spatial distribution,Shanghai had the highest coupling coordination degree,and belonged to type II;secondary to Shanghai were Suzhou and Hangzhou,which belonged to type III;the areas in the south of Jiangsu Province,and Zhoushan and Huzhou of Zhejiang Province had the lowest coupling coordination degree,and belonged to type V.(2) As seen from the sequence of improvement in economic development and quality of residents life,the Yangtze River Delta region was mainly embodied as type B and type C,reflecting that each city paid attention to different directions.Wherein,Shanghai,Suzhou,Nantong,Yangzhou,Zhenjiang,Taizhou and Zhoushan were of type C,and paid attention to the synchronous development of economy and the quality of residents life; Hangzhou and Huzhou were of type B,and paid more attention to enhancing the quality of residents life;Nanjing,Wuxi and Changzhou in the south of Jiangsu Province,and Ningbo,Jiaxing,Shaoxing and Taizhou of Zhejiang Province were stable of type B in recent years,and this reflected that,these cities began to pay attention to enhancing the quality of residents life gradually
