Can socially sustainable development be achieved through homestead withdrawal? A hybrid multiple-attributes decision analysis

Achieving sustainable rural development is essential for countries worldwide to balance development between urban and rural areas; especially, sustainable social development is crucial. In the face of rapid urbanization in China, the withdrawal of rural homesteads (WRH) has become the core policy for attaining sustainable rural development. Compared with the literature that focuses on the economic or environmental impacts of the policy, few studies have evaluated how social sustainability is accomplished through such land-reform policies. Given the consensus that exploring sustainability emphasizes complex causal relationships between multiple dimensions, assessment models must further consider interdependencies. Based on Chinese expertise and perspective, this study proposes a hybrid multi-attribute decision analysis model to evaluate the contribution of WRH policies toward social sustainability. First, the Delphi method was used to build evaluation criteria covering four dimensions—the socio-ecological environment, social welfare, social equity, and social inclusion—and 20 criteria were based on the existing literature. Second, influential network relations maps (INRMs) were constructed based on the fuzzy decision-making trial and evaluation laboratory (DEMATEL), considering complex causal relationships between dimensions and criteria to further identify the key evaluation criteria for the social sustainability of the homestead exit policy. The results show that the five subdimensions are key to achieving sustainable social development through WRH. Based on our results, we propose certain policy recommendations.
