In this study, our focus is on the estimation of pricing function in the office and residential floor space. That is we would examine the difference in profitability of land uses. In our hypothesis, the social costs emerge when the estimated rent for office use is cheaper than the rent for residential use on the same location. In other words, there is in inefficiency in the land use. Our analysis showed that 14,577 office buildings, 27,58% of 52,890 total office buildings as of 1991, would achieve higher rent if they are converted to residential use in 2004.The total difference of the rents is 35 billion and 981 million yen per year as opportunity loss. Furthermore, we can see through our analysis that the office buildings were converted to residential properties where the rent for residential use is higher than that for office use between1991 and 2001. This result supports our assumption that is the land use would change to another land use which produces higher return.}, pages = {1--29}, title = {土地利用の非効率性─東京都区部・事務所市場の非効率性の計測─}, volume = {21}, year = {2007}, yomi = {シミズ, チヒロ and カラト, コウジ} }
