Abstract:

The land use status of Nanjing City was investigated by using the crossdata of land, capital and labor in 2009. The C2R model and Data envelopment analysis (DEA) approach were used to quantitatively analyze and evaluate the intensive land use efficiency of Nanjing City in 2012.The results show that intensive land use efficiency of Nanjing has not reached the summit level. In nonDEA efficient area, the land input was sufficient while the land output was not. The scale return of city areas has reached the optimal value while the suburb areas have not. For the structure return of most areas has not reached the optimal value, the land use structure should be optimized to increase the land use intension. While the efficiency of capital input was high, the efficiency of intensive land use was insufficient
