I would like to make some comments here:
(1) would you like to try fitting the data after making logarithm transformation? so that this nonlinear problem becomes linear, and could avoid using stepwise functions. (refer to Logistic Regression)
(2) It seems to me you are pursuing an overfitting in your study, which could miss general underlying relationships. For instance, your discovery may work well only in China case, but not in other countries, say US case.
(3) "70" comes from applying Taylor Series Expansion on (1+x)^n=2, where n denotes # of years, x denotes GDP growth rate. For even more details, please show me the money first.
