Social Benefit Evaluation of Shantytown Reconstruction Based on DEA: A Case Study of xI'an, China

In recent years, with the rapid process of urbanization in China, shantytowns have gradually become the bottleneck of urban sustainable development, reconstruction of which is also the urgent desire of the public, especially the residents of shantytowns. In view of previous studies on shantytowns reconstruction generally focused on economic benefits, this study aimed to promote shantytown reconstruction by presenting policy recommendations based on a diagnosis of AHP-DEA with a focus on the social benefits. As a result, Xi'an was taken as a typical city and index system with 7 effects and 23 indicators of social benefit influencing factors was established, which then used in CCR and BCC models. Conclusions showed that the overall level is good, but the output and investment are not balanced, especially for the inconvenient medical education and poor living environment. In the background of new-type urbanization, government, community and self-governing organizations should strengthen the cooperation to play a greater role, and ultimately enhance the social benefits of shantytowns.
