| To promote the economic development of the population flow and service demand of urban growth, and promote the business economic activity.Business activities plays an important role for urban elements accumulation and economic control and decision-making have important influence Firstly, from the research background of the real estate business, this paper analyzes the present research in this field in China and the current situation of the development of the real estate business, and literature research, the research questions, research methods and significance are briefly introduced. And then to construct the theoretical basis of this paper, including land rent theory, the hedonic price theory and statistical theory. Based on the research framework and theory as the guide, taking Chongqing city as a research sample, using the survey to collect data and spatial analysis and statistical software, build Chongqing city commercial real estate rental model, including the traditional hedonic price model(OLS), spatial error model(SEM), spatial lag model(SLM). To verify the use of econometric theory precision of the three models, in order to validate the model, using cross validation method. Finally, through the optimization model, the spatial error model prediction accuracy is better goodness of fit, and finally analyzes the variation law of Chongqing city commercial real estate rental space by using Kriging interpolation method, and provides some constructive suggestions on the planning of Chongqing city business district.Through the above research, this paper draws the following conclusion:①From the rent of regional distribution point of view, Chongqing central commercial real estate rents is high, surrounded by low trend. At the same time, Monument for Liberation, Nanping and Jiangbei District business rents overall high, Shapingba, Jiulongpo, Dadukou business rental growth trend is relatively slow.From the spatial structure, Chongqing city commercial real estate showed a "multi center, the structure characteristics of fan", and the existence of radial structure with CBD as the core.②Compared with the traditional hedonic price model, spatial hedonic price model has better explanatory ability. In the model selection, spatial error model’s goodness of fit and prediction precision is the best. This model can be widely used in the research of commercial real estate rental model.③The model regression results show that the district level, financial services, hotel have the highest influence on the rent. The density of road network, medical service and bus stations have the weakest influence on the rent. It also reflects that unlike the residential real estate,commercial real estatepays more attention on the business function rather than life function. |
