Comparing Study on Approaches of Identifying Indicators' Benchmark for Sustainable Development

Based on literature study, three principles of identifying benchmark were formulated, and four general approaches of benchmark recognition were summarized. We adopted Beijing sustainable development indicators as a sample to test each approach, with which we could compare the results and analyze the characteristics, advantages, disadvantages as well as suitability. The research results showed that indicators with different characters should be treated with different approaches for benchmark identification.
