ABSTRACT
Since, a certain degree of subjectivity exists in determining of weights in gray relational analysis and the DEA analysis can only evaluate whether the unit is efficient, but the effective unit cannot be ordered, data envelopment analysis (DEA) and weighted grey correlation have been combined to achieve fairness and objectivity of the evaluation results. An evaluation system from the perspective of input and output for the coordination of urban ecosystem has been established and an empirical application of urban ecosystem in Shanghai has been carried out to verify the validity of this method.
