Marine Ecosystem Service Value Re-valuation in China Based on Hierarchical Meta-analysis
Based on stated preference valuation studies of China's marine ecosystem services,carried out between 1996 and 2021,this paper presents a meta-analysis of marine ecosystem services benefit estimates using a Hierarchical Linear Modeling(HLM)approach.Results indicate a range of factors that influence the estimated economic values of China's marine ecosystem services,including ecosystem area,type of ecosystem,respondent's identity,regional GDP per-capita,ecosystem services being valued,valuation method and hypothetical scenario being employed.The meta-regression results also indicate that willingness to pay for marine ecosystem services in China depends largely on people's perception of the importance of the ecosystem services,which is influenced by national policies,educational levels,and the degree of connection between these services and people's lives.This is evidenced by the fact that people have a higher willingness to pay for coastal wetlands and recreational services.Furthermore,it was found that people are most willing to pay for conservation scenarios,contrasting with lower willingness for environmental compensation scenarios.These findings contribute to research on the valuation of marine ecosystem services in China and to the incorporation of the results into ecosystem-based management decisions by clarifying the effects of different factors on the valuation estimates.
