Circulation potential of rural collective construction land based on the view of economic development A case study of Chongqing city

The rural collective construction land transfer is benefit for improving land use rate and increasing construction land stock. It爷s also a significant method to promote the integration of urban and rural land market. The transfer potential measurement is important basis that can quantify the transfer amount of rural collective construction land and arrange construction land indicate properly. Due to the existing calculation model do not consider the differences of economic develop speed and no typical characteristics of protective reserved area, this article used economic analysis and methods to build the potential measurement model of rural collective construction land transfer. Then taking Chongqing as a example and 2011 as the base year, authors predicted relevant modified index data of all counties in Chongqing of 2020 and identified protective construction land ratio according to reclamation correction factor. In this way it could measure the real potential of Chongqing rural collective construction land transfer. The results show that:(1)Chongqing rural collective construction land can reach 19 800.48 hm2 in 2020 and has obvious differences among the counties, those differences exist in one-hour economic circle including Yuxi economic corridor. (2) The update of transfer potential calculation model makes the total amount of land transfer and the distribution order of all counties more accurate, this has a positive significance for improving the accuracy of potential calculation of rural collective construction land.
