摘要
我国水产品市场已经出现了区域性、结构性的供大于求及价格持续下降的现象。为此,对水产品价格进行预测是必要的。以1978～1999年数据为样本,利用时序组合模型对2000年的水产品收购价格进行了预测研究。
At present supply of aquatic products had exceeded demand and there appeared territorial and structural disequilibrium in the domestic aquaculture market. As a result the price of aquatic products is continuously down. So that price prediction had became the main problem in fishery economic. In this paper we had predicted farmer price of aquatic products in 2000 via time series decomposed model sampled between 1978 and 1999. [
