To improve the income of vegetable producers and understand the influences on vegetable producers because of the rising in the vegetable prices, adopted the anonymous sample to do an investigation, the results are shown as follow. Firstly, most of vegetable growers think that vegetable prices should rise and continue to rise, and the rising in vegetable prices will lead to the increasing incomes. Therefore, some vegetable varieties that their prices are increasing obviously will be enlarged in planting the next year. Next, because of the increasing in logistic costs and production costs, partial vegetable producers get meager profit even though the vegetable prices are increasing. Besides, most of vegetable growers have high expectation on the price tendency and their productive process is short of plan and prospect. Finally, the sown area of a single vegetable is always determined by the market in the last season. Aiming at the influences on the vegetable producers behavior as the rising in the vegetable prices, their thinking model should be transformed, the information platform of rural area should be perfected, and the production base should have more investments. Hence, the incomes of vegetable producers can be improved
