研究了利用元分析方法进行游憩经济评估的利益转移方法。由于元回归模型考虑了研究对支付意愿（WTP）估计的一些特定影响，因此使用元分析的利益转移可以对未研究的娱乐资源产生有效的WTP估计。meta分析收益转移的收敛效度使用来自美国的样本外原始研究进行测试，分析使用百分比差异，配对t检验，回归和相关检验进行。结果表明，利用meta分析的收益传递函数（BTF）估计的WTP值与样本外原始WTP值之间的收敛性存在差异。估计的WTP值与原始WTP值之间有相当高的百分比差异（80-88%），通过配对t检验，平均差异具有统计学意义。然而，相关和回归结果一致显示，国家BTF估计值与原始WTP值之间存在显著的正相关关系，表明存在一定程度的收敛。结果表明，在无法进行“最优”评价的情况下，国家主体功能区表现优于区域主体功能区，表明国家主体功能区具有游憩效益转移的潜力。
A benefit transfer approach to recreation economic valuation using meta-analysis is examined. Since the meta-regression model takes into account some of the study specific effects on willingness to pay (WTP) estimates, benefit transfer using meta-analysis could yield a valid WTP estimate of unstudied recreation resources. The convergent validity of the meta-analytic benefit transfer is tested using out-of-sample original studies from the U. S. The analyses are performed using percentage difference, paired t-test, regression and correlation tests. The tests reveal mixed results on convergence between estimated WTP using meta-analytic benefit transfer function (BTF) and out-of-sample original WTP values. There is a fairly high percentage difference between the estimated and original WTP values (80-88%), and the mean differences are statistically significant as shown by paired t-tests. However, correlation and regression results consistently show significant positive relationships between national BTF estimated and original WTP values indicating some level of convergence. The results show that the national BTF outperform the regional BTF indicating a potential of the national BTF for recreation benefit transfer when a "first best" primary valuation study is not affordable.
