Of endogenous variables with the Root-Mean-Square Percent Error between simulated values and actual values less than 5%, and 81. 8% of endogenous variables with RMSPE less than 10%, which implies that the overall goodness of the model is satisfactory.

检验结果表明，动态模拟值与实际观测值的均方根相对误差低于5%的内生变量占全部内生变量的59.1%，而均方根相对误差不超过10%的内生变量占81.8%，说明模型对观测值具有良好的总体拟合性能。

Since the number of trips is a non-negative integer, truncated, and of endogenous stratification, this study empirically analyzes its recreational benefits by the On-site Poisson and truncated negative binomial with endogenous stratification of the Travel Cost Method. Besides, this study adopts TNBES to see how the number of trips disperse and takes the consumer surplus to assess benefits. As to visitors' valuation, this research uses the ordered probit to do empirical analysis and then divides all satisfaction factors by the factor analysis and cluster analysis into four factors and two clusters, which then are taken as explanatory variables.
