Analysis Efficiency Of Urban Land Utilization In Anhui Province Based On Three-stage DEA Model

With the development of urban economy and the continued urbanization drive, cities in Anhui Province gradually exposed problems like tensions between people and land, increasing shortage of land resources and so on. Although the research on efficiency of urban land utilization has aroused extensive attention from the academic community, but the complexity of land utilization system is gradually revealing shortcomings of the classical method, and there are comparatively few works which discuss efficiency of urban land utilization in Anhui Province at the same time. Therefore, with the help of a more scientific and perfect theoretical model, analysis of the current situation of urban land utilization in Anhui Province, and discussing the direction of policy about raising the land use rate, is of great practical significance to promote the process of urbanization in Anhui Province and to ensure a healthy social and economic development.Based on a summary of the domestic and foreign literature, we calculate the efficiency of urban land utilization in Anhui Province based on three-stage DEA model in this paper. What’s more, we not only discuss the current situation and changes of urban land utilization, but also analysis the effects of land policy from the perspective of China’s system, and study the efficiency difference of different cities from the angle of typical city types. The main content includes four aspects as follows:First of all, we will calculate the land utilization efficiency of16cities in Anhui Province (excluding Chaohu) from2000to2012based on three-stage DEA model. In the first stage, the initial input variables, output variables and economic operation environment variables about land utilization efficiency will be put into BCC model in order to calculating the classical DEA efficiency. In the second stage, for the sake of eliminating interference of economic operation environment factors and random errors, SFA will be applied to separate the external distractions. And the initial input variables and output variables about urban land utilization will be adjusted accordingly. In the third stage, the final DEA efficiency will be figured out based on the adjusted input variables and output variables. The final results can represent the efficiency level of urban land utilization in Anhui Province more accurately and objectively.Secondly, we will evaluate the efficiency level which has already been figu-red out. In this part, we’ll evaluate the overall efficiency level of urban land utilization in Anhui Province with spatial and temporal perspectives, and analysis not only the influence of land policies, but also the efficiency changes of different typical types of cities in Anhui Province. The results show that, the spatial distribution of urban land utilization efficiency types in Anhui Province is as the symmetric axis, and most cities in Anhui Province in a slight effectiveness or low effectiveness state. There are three important time points of the efficiency change. And the three important time points have a certain relationship with those important land policies. Moreover, different types of cities have different efficiency scores and different stabilities.Thirdly, the main factors will be analysised based on the panel data regression model and empirical results of economic operation environment factors. During input factors analysis, panel data quantitative analysis will be applied to study the main input variables’influence over the efficiency of urban land utilization in Anhui Province. The results show that urban construction land fixed-asset investment, local financial expenditure and employment in second--dary industry have significant positive influence on the efficiency of urban land utilization. However, the influence of employment in tertiary industry is not significant. At the same time, in the economic operation environment factors, urban infrastructure helps to increase the efficiency of urban land utilization in Anhui Province, while technology environment and degree of foreign trade dependence are not.Finally, after summarize the main conclusions of the study above, we’ll try to put forward policy recommendations to increase the efficiency of urban land utilization, according to the main conclusions and the actual situation of Anhui Province.
