【摘要】The metropolitan resources comprehensive efficiencies (also called

comprehensive

technical

efficiency,short

for

CTE,thereafter),change trends and causes are investigated using DEA and Malmquist index models,respectively,in China during the period 1990-2006.Firstly,the DEA model results show that the metropolitan CTE was just fair to middling with the characteristics of almost declining from the Eastern Coastal to Western China,and only few metropolises were DEA efficient.Secondly,the results also show that the PTE was correlated with the urban population sizes of metropolises negatively,and the SE correlated positively with the urban population sizes of metropolises in 1990,2000 and 2006,that is,with urban population sizes getting larger the corresponding PTE was decreasing accordingly,and the SE was increasing consequently and the increasing rate was smaller with the scale increase.Thirdly,the influencing factors of metropolitan

efficiency

were

SE

and

PTE

in

1990

and

2000,respectively.But the PTE became the predominant influencing
