Built-up land expands with China's economic growth, while it is not utilized efficiently. This study takes capital, labour and built-up land as input factors, and gross domestic product (GDP) as output factor to analyze the technical efficiency of each province from 1997 to 2007 by adopting input-oriented CCR model with Data Envelopment Analysis (DEA). The research results show that the average technical efficiency of most provinces is low, which is consistent with their economic development levels. By calculating the average technological efficiency of each province during two periods of 1997-2002 and 2003-2007, it is found that the technological efficiency in 21 provinces during 2003-2007 is lower than that during 1997-2002. This tendency is in coincidence with the accelerated development of the heavy industry and the chemical industry during 2003- 2007. There is an evidence that the inputs of capital, labour and built-up land are slack,which means those inputs are relatively excessive and not allocated appropriately.

Key words: built-up land, China, data envelopment analysis (DEA), economic growth, efficiency
