Abstract:

The existing studies on potential evaluation of urban land intensive use mainly adopt the multi-index comprehensive evaluation approach, which has defects such as insufficient basis, incomparability of results and difficulty in reflecting dynamic changes. In view of this, this study introduced the theory and method of technical efficiency measurement into the potential evaluation of urban land intensive use. The potential of urban land intensive use can be defined as the land savings or output growths potential brought by the possible improvement of technical efficiency. Based on measuring the technological efficiency of urban land use with the SFA method, this paper constructed the quantitative evaluation models of land saving and output growth potential of urban land intensive use, and then measured and analyzed the scale and proportion of land saving and output growth potential in the Beijing-Tianjin-Hebei region during 2006-2015. The results show that the potential scale of urban land intensive use in the study area is very large and continuously increasing. The annual average of land saving potential scale is 709.80 km 2, and the net increment in the 10 years is 543.96 km 2, while the output growth potential scale is 420.76 billion yuan (the constant price in 2005), and the net increment in the 10 years is 342.86 billion yuan. The results also indicate that the potential proportion of urban land intensive use in the Beijing-Tianjin-Hebei region is quite high and continuously rising. The annual average of land saving potential proportion is 21.80%, or an increase of 10.56 percentage points in the 10 years, while the annual average of output growth potential proportion is 26.12%, or an increase of 14.73 percentage points in the 10 years. The potential ranking between the 13 cities is stable and the gap is widening, showing the general rule that it is more difficult for developed cities and easier for underdeveloped cities to explore potentialities, as well as the Matthew effect that it is easier for the easy and more difficult for the difficult. The research can provide scientific guidance for the practice and management of urban land intensive use and facilitate the dialogue and exchange between intensification evaluation and efficiency measurement.
