A Comparison of Eco-city Construction Capability Between Xuzhou and Lianyungang

This paper proposes an eco-city index system by considering the practical features of Xuzhou and Lianyungang, which is then used in a quantitative analysis of correlation and generalized principal components for the eco-city construction and in a comparison of eco-city construction level between Xuzhou and Lianyungang from 1995 to 2004. The study indicates that the economic and social ecosystems in Xuzhou and Lianyungang see a rapid development from 1995 to 2004 and the situation in Xuzhou is better than in Lianyungang, but the environmental ecosystems of the two cities see a decline at first and then a rise, and the situation in Xuzhou is worse than that in Lianyungang. It may be concluded that the whole level of eco-city construction of Lianyungang is better than that of Xuzhou.
