The initial minimal effort at turning point model describes the minimal effort on transferring agricultural surplus labor into non-agricultural labor, but did not involve in annual effort.We revised and expanded the initial model, and the new ones include annual efforts.Comparing initial model with revised model and expanded model, we found that the results based on initial model are quite different from the actual conditions, while the results based on revised model and expanded model fit the actual conditions well, especially for the expanded model.Furthermore, using the expanded model to research the effort of tertiary industrialization, we found that the tertiary industrialization is fully developed already in China.
