Along with the steady growth of population and economic
development, together with the rocketing of land price, urban
lands are forced to be developed increasingly intensitive.
Associated with large scale developments, excessive demands for
infrastructure and public services are then created. Based on
the concept of "paying for growth", development impact fees
(DIF) are imposed in U.S. in order to internalize the external
cost, land use are controlled indirectly through the market
mechansim. In Taiwan, most related previous studies dealt with
environmental impact assessment and the caculation of impact
fees. In this study, it is focused on the analysis of various
DIF imposition effects in terms of economic, equity and land
use aspects. In addition, feasibility of different imposition
methods in Taiwan is investigated. In terms of methodology and
content in this study, alternative imposition methods of DIF
are formulated firstly, and then evaluation criteria are
identified to set up an AHP (Analytic Hierarchical Process)
based evaluation framework. Finally, a sample of government
officials are surveyed, sensitivity analysis of the surveyed
results are also followed. From the evaluation, it is found
that construction and mitigation by developer (donation of
physical objects) is most prefered by government officials
under different weighting scheme, paying fee and land donation
are the next. To achieve the best function of the impact fee
system, it is argued that imposition methods should be flexbily
exercised in different local areas. It is finally suggested in
this research that land donation should be imposed in short
term because of its on-site exaction ease, cash payment and
donation of physical objects can then be introduced gradually
in the long term.
