Abstract

Abstract: Ensuring inclusive and equitable quality education is a primary goal in the United Nations' agenda for sustainable development. Under this global initiative, China has been striving to achieve equitable education in rural areas through the planning and development of rural schools. To this end, the paper focuses on the rural school planning issue by proposing an evaluation-optimization-validation framework in a case study in Changyuan, a county-level city in China. Specifically, by focusing on the nine-year compulsory education institutions, including elementary schools, junior high schools, and nursery schools, the paper first identifies the low-school-accessibility areas by a modified Huff three-step floating catchment area (MH3SFCA) method. Then, the paper optimizes the school locations using the maximum covering location problem by the complementary coverage (MCLP-CC) model by improving the equity of school access. Lastly, a comparative analysis before and after the optimization reveals that except for elementary schools, the spatial equality of the school-specific accessibility and that of the overall accessibility have both been improved to a significant degree. The proposed framework provides a new scientific procedure for schools' location planning, and the implementation results can provide insights into future planning initiatives to promote educational equity in rural China and beyond. Highlights: We proposed an evaluation-optimization-validation framework for schools' location planning. By integrating accessibility evaluation and MCLP-CC optimization method, the maximum coverage of schools is optimized. Villages not covered by the junior high/elementary/nursery schools is reduced by 62.55%, 70%, and 84.30% after optimization. In line with the UN SDG goals, the proposed approach significantly improves educational equity in rural Changyuan, China.
