ABSTRACT
The economic value of goods and services provided by ecosystems is progressively revealed by estimation using the contingent valuation method and conjoint analysis (TEEB 2010). However, this value is not yet reflected in GDP or national accounting, and there are few studies on the contribution of ecosystems and biodiversity to GDP. One example is the econometric analysis with the time series data of ecosystem services and GDP conducted by Richmond et al. (2007). In this analysis, the contribution to GDP of net primary production, which is perceived as an alternative to ecosystem services, was estimated using the Cobb-Douglas production function. As a result, it was demonstrated that a 1 percent increase in the rate of change of net primary production will raise the actual GDP growth rate by 0.09 percent.
