The article explores how to evaluate non-market public goods like urban and suburban environments. Researchers modified and applied methods to assess these goods for environmental upgrade programs. They studied various programs, including urban environment enhancement, cultural heritage protection, noise pollution control, wetland restoration, and port pollution cleanup. The Contingent Valuation Method was used to measure citizens' willingness to pay for lost public goods. Findings show that residents in different areas have varying sensitivities to environmental issues, with some preferring mild improvements over drastic changes. The study also assessed volunteers' willingness to participate in cultural heritage reconstruction projects.
