[006] Research on the construction of urban land price index in Taiwan
Keywords:Base, Metropolitan area, Land Price Index
Taiwan currently has a land price index compilation method, which uses urban areas as the release range, and uses the Fiji formula to select the mid-price segment as the target land price for evaluation, and conduct index calculation. However, in practice, if the land price grades are reclassified, it is necessary to re-select the mid-price segment, and collect transaction cases in the segment to compile the land price index, which leads to many issues. In particular, for the future application of land price benchmarks and with a large number of computerized valuation techniques, the suitability of the current Fibonacci formula for compiling the index is also worth discussing. Therefore, this research empirically uses the benchmark land to replace the regional land price index, conducts the trial calculation of the national and residential area, commercial area, and industrial area land price index, and further analyzes the trend of the residential price index, and finally compares the differences under the compilation of different indexes. , based on the research and development of land price index improvement strategies and suggestions. According to the results of this research, the "Laplace formula method of weighted median benchmark land price and area" is used to set the base period of the construction of benchmark land price data in 103 as the base period, and the revised growth to 106.59 in 2010 (an increase of 6.59%) in the following year, Then the 105-year index was 104.63 (1.96% down from the previous year), the 106-year index was 103.25 (1.38% down from the previous year), and the 107-year index was 102.24 (-1.01% down from the previous year), It has been slightly revised down year by year, until 2010, due to the influence of the real estate market, the index trend was revised down significantly to 94.57 (a decrease of 7.66%). To put forward relevant suggestions and improvement strategies, so as to provide a reference for improving the compilation of the land price index in the future.
