Taiwan is currently introducing the Growth Management
Mechanism in order to prevent its cities from inappropriate
development. To find the best directions for city growth
management, urban planners should have comprehensive
informationpertaining to the advantage and disadvantage aspects
of different city developmenttypes. It is the purpose of this
paper to introduce efficiency as an index forevaluating these
development types; "efficiency" is expected to help producing
the right course of development. In this study, we set up a city
efficiency evaluation model based on the DEA theory, toghter
with previous researches ofcity development types, we conducted
an evaluation of efficiency of the overallTaiwan area and a
comparative analysis of the efficiency of different city types.
The area of this study includes ninety cities whose population
is over fifty thousands. Empirical evidence revealed that
most cities【n Taiwan fell in the non-efficientlevel and only
about one third reached the relatively efficient level in 1991
and 1995. Technical efficiency and scale efficiency reveal that
some cities fell in thenon-efficient level because of its wrong
size. Slackness analysis reveal that lack of output is the main
reason for non-efficiency, the influence of input indexis more
little. Sensitivity analysis reveal that closing of each local
governmentand amount of citizen''s income have a great influence
to efficiency. Analysis ofthe return to scale reveals that most
cities are in the stage of Increasing Returnto Scale. Second,
this study used multi variable analysis in combination with
growthmanagement relative indicator to classify city. According
to factor analysys,we get four factors, includes development
strength of housing and business, levelof economics development,
growth of population and function od industry, and quality of
institution. Empirical evidence revealed that cities in
Taiwan can be divided into fivetypes, includes ordinarily
cities, growth cities, center cities, the city whoseinstitution
had better quality, and Statellite cities of the metropolitan
areaor local center cities. To comparative analysis and test
of efficiency of different city types, theresult demonstrated
different efficiency. It showed that higher rank or big
sizecities have better efficiency level.
