Abstract: Han River Ecological Economic Belt covered some cities and counties in Hubei,Henan and Shaanxi provinces,and was an important part of the Yangtze River Economic Belt.However,in the actual development process of Han River Ecological Economic Belt,there were some problems,such as obvious regional differences,unbalanced industrial development and serious ecological damage,which seriously restrict the socio-economic development of Han River Ecological Economic Belt.Therefore,on the basis of constructing an evaluation index system of economic development quality,which included four dimensions of economic development effectiveness,economic development innovation,economic development sharing,economic development sustainability with the relevant index data of 14 cities in Han River Ecological Economic Belt from 2010 to 2017,the weight of each index was determined by principal component analysis,and the horizontal comparison and vertical comparison were made.The results showed that although the quality of economic development in the Han River Ecological Economic Belt was increasing year by year,but the innovative and sharing growth of economic development were slow,and the sustainability of economic development showed a downward trend in the later period.Finally,specific suggestions were put forward to improve the economic development quality of Han River Ecological Economic Belt.

Key words: Han River Ecological Economic Belt, economic, economic development quality
