近年来,我国蔬菜类农产品“卖难”问题层出不穷,“微博叫卖”、“为农户找买家”现象此起彼伏,但治标不治本。对此,文章从造成农产品“卖难”问题的根源出发,通过运用BP神经网络预测模型对我国蔬菜供需量进行了预测,研究发现在蔬菜消费需求量只有微小变动的情况下,其实际供给量连续多年远高于理论供给量。为此,从合理预测供需、指导农业生产的角度提出了一些针对性的对策建议。
近年來,我國蔬菜類農產品“賣難”問題層齣不窮,“微博叫賣”、“為農戶找買傢”現象此起彼伏,但治標不治本。對此,文章從造成農產品“賣難”問題的根源齣髮,通過運用BP神經網絡預測模型對我國蔬菜供需量進行瞭預測,研究髮現在蔬菜消費需求量隻有微小變動的情況下,其實際供給量連續多年遠高于理論供給量。為此,從閤理預測供需、指導農業生產的角度提齣瞭一些針對性的對策建議。

In recent years,the“hard sell”problem of China’s vegetable produce have emerged in endlessly. The phenomenon of“Hawk”and“to find buyers for farmers”happens now and then,but it is just a temporary action instead of total solution. To this,from the root of the“hard sell”problem of agricultural products as the starting point,by using the BP neural network prediction model,the amount of supply and demand of vegetables in our country is predicted. It is found that in the situation with only minor changes in vegetable consumption demand, the actual supply is much higher than theory for many years. Therefore,some corresponding countermeasures and suggestions are put forward from the perspective of a reasonable prediction of supply and demand,as well as a scientific guidance of the agricultural production.
