- The assessment structure for social-economic risk was established with three indices and 11 sub-indices. The SEA principle was considered as sub-indices in the assessment structure. The AHP method is used to calculate the weights of assessment factors, while fuzzy AHP is used to assess the relative importance degree of the SEA principles. The integration of fuzzy AHP and SEA principles can give a qualitative assessment for social-economic risk in urban development.
- Assessment results show that the management system is the most important factor in urban development. For the six principles in SEA, the optimized relative importance degrees of the factors of sustainable development (A) and monitoring measures (E) are greater than other principles. Therefore, the principles of sustainable development and monitoring measures in SEA should be strictly implemented during urban development.
- In the future, it is recommended that the government establish a unified management system for both urban and rural areas that can ensure the effective implementation of sustainable urban development. The supervision capacity of government authorities to prevent unauthorized rooftop additions also needs to be strengthened. Mandatory regulations for construction projects in China, particularly for private self-constructed work undertaken on house-building sites in rural areas, should be strictly carried out.
