Prediction on the developing trend of global electric automobile based on the logistic model

The paper gives the prediction and analysis on the global electric automobile market based on the logistic model, which provides the decision-making reference to the domestic electric automobile enterprises. In the process of parameter estimates, the paper gets the different level of curve estimation by selecting different value of K. Through the compare of the different level of curve estimation and different value of K, the paper selects the best model of curve estimation on the global automobile market. With the compare of the growth curve and S curve, the paper finds the logistic model has the high level goodness-of-fit of curve estimation. Then the paper gives the data prediction and analysis with the logistic model. The predicted data shows that the global electric automobile market will step into the stage of high-speed developing growth.
