Urban Land Use Intensity and Efficient Evaluation in X City: Based on Principal Component Analysis

Abstract

In order to assess the performance of urban land use in X City and to identify the problems in land use, principal component analysis is used in this paper to assess urban land use intensive and efficient. By seeking to local Statistical Yearbook, the local government work report, the local government budget and its implementation report and other related information on X City, the study collects land use performance indicators data from 2002 to 2008. Analysis results show that the first principal component score is quite close to the composite score sort, which indicates that the first principal component explains most information of the overall level. Empirical results show that X City urban land use efficiency is increased year by year from 2002 to 2008. That is to say, along with increasing input of urban land use, land-use intensity enhanced, and the continuous optimization of urban land use structure, X City efficient and intensive urban land use has become increasingly prominent. Therefore, we should pay more attention to the development of tertiary industry in aspects of urban land productivity, to further improve the output level of urban land in the future. It should be noted that idle land rate up to 30.7% in 2008 is due to the international financial crisis.
