Abstract

With the object of improving the validity of Land Price Fluctuation Rate, the present study developed new land supplementary price indexes in order to correct discrepancy between actual land price and the land price index in the current system of surveying and assessing Land Price Fluctuation Rate. As indexes supplementary to the land price index, we proposed land price index for eup, myeon and dong areas, land price sudden‐rise index with adjusted weight regardless of the volume of land trade, and trade frequency index in consideration of the volume of land trade. According to the result of the simulation of the land price index for eup, myeon and dong areas and supplementary indexes, the land price index for eup, myeon and dong areas, the land price sudden‐rise index and the trade frequency index appeared to have a higher discriminating power than the land price index for cities, counties and districts. Utilizing the land price index for eup, myeon and dong areas, the land price sudden‐rise index and the trade frequency index, the government can enhance the promptness and accuracy of its policies and increase the rationality and objectivity of various real estate policies. For the full application of the proposed supplementary indexes, however, it is necessary to execute simulation using more various areas and methods and improve its appropriateness. Thus, the present study made a new proposal of indexes supplementary to the land price change rate, and expects diverse subsequent researches.
