Although large volumes of empirical studies on assessment of biodiversity valuation have been and are being carried out both at home and abroad, results of the assessments that so far have been done vary quite sharply, thus it is more difficult to use results of the assessments in policy-making on biodiversity conservation and in implementation of the policies. The meta-regression technique has been used for reexamining the factors that determine the study-to-study variance and exploring the variables that explain the variation based on the findings of the researches at home and abroad on biodiversity valuation. It has been found that the estimated effect-size of biodiversity valuation is significantly related to type of value, valuation method, time of the study conducted, economic or income level, as well as type of the publication, while the research scales and sources of literature did not make much difference. It is suggested that while making use of research findings available in assessing biodiversity valuation, it is essential to pay attention to source of the deviation of the assessment using meta analysis, and that in view of the fact that no much difference is found between the researches at home and abroad, it is advisable to use findings of the researches abroad as reference in unfolding researches on assessment of independent valuation.

Key words: meta-analysis, biodiversity, valuation
