A Comprehensive Measurement of the Utility of Land Use of 16 City-regions in China
从能力、结构和强度三个维度构建指标体系，用熵权法赋权并聚类，测度了16个中国城市区域的土地利用效用，发现整体中等、沿海与内陆差异明显。
The utility of land use of city-regions,which is defined as the comprehensive performance of the socio-economic activities that utilize the land,proves crucially significant in sustaining the development of city-regions.It can be measured in three dimensions,i.e.capacity,structure and intensity.Following that conceptual framework,we conducted a comprehensive measurement of the utility of land use of 16 city-regions in China by building up a hierarchical index system,scoring the three dimensions weighted by the entropy of the indices,and systematic clustering the 16 city-regions based on the three groups of scores.The results show a moderate utility of land use of city-regions in China as a whole and highlight the spatial discrepancy from the coast to the hinterland.High-utility city-regions perform well in the capacity and intensity dimensions.Moderate-utility city-regions score high in the capacity dimension,remain inferior in the structure dimension and enjoy a huge intensity potential to be tapped into.Some of the low-utility city-regions,however,reach an above average level only in the structure dimension.
