Nanjing is a major city in the Yangtze River Delta of China. Since the 1990s the city space has been expanding rapidly in relation with the fast economic development and urbanization. The policies of land saving and intensive land use has been emphasized by the government to protect the arable land from converting into urban land. After analyzing composition of present policy instrument in Chinese cities, this paper noted that urban planning and land use regulation were the regular basis. The effectiveness of urban planning control and administrative efficiency of growth management efforts were discussed. Firstly, the paper substantively studied the process of urban expansion along two transportation lines based on the remote sensing data of Nanjing obtained in 1986, 1996, 2002 and 2005, and assessed the effectiveness of urban growth management with the efficient index on newly converted urban land (Eg), the cumulatively efficient index (E) and the ratio of idle land area. The E of Nanjing master urban plans was about 70% in the first five years. The Eg was relatively low, being 0.29-0.7. Secondly, the logistic regression analysis with the data of 478 land parcels from the sampling sites revealed that the urban plan significantly decreased occurrence frequency of the idle land parcel (p < 0.001), and the administrative factors were significantly related with the frequency of idle land parcel. Concentration and reserve of rights in land use administration and urban plan management have negative effect on idle land frequency. Finally, some urban planning and land use policies such as enlargement of the urban planning area, rights reserve in urban plan administration and land use transformation approval have been suggested to improve the land use efficiency. The results and suggestions should benefit urban land management in land saving and intensive use of urban land, and the methodology of quantitative assessment on effectiveness of urban growth management should give examples for the similar studies in China.
