| Abstract: | Based on the trait of green vegetable selling now, the problem is concerned with the study of the price forecasting of green vegetable in network environment. As the example of the single vegetable species cabbage, its price problem is studied quantificationally in the facts of identification, diagnose, mimic and forecasting by using ARIMA model. As a result, think over the unilateralism of single species, the method which is aim of the weighted average price of 16 vegetable species is put forward. |
