我国养殖水产品供给反应研究

Study on supply response of aquaculture in China

论文依据2000-2013年我国淡水养殖、海水养殖水产品产量和价格数据,应用Nerlove模型,对我国淡水、海水养殖供给反应进行了实证分析。结果表明,前期养殖产量对养殖水产品供给的影响作用较大;价格对淡水养殖产量影响不显著;海水养殖产量受价格影响显著,但是短期、长期供给缺乏价格弹性。因此,为确保我国水产品长期有效供给,满足日益增长的水产品需求,需完善养殖渔民的补贴政策,加大信息服务建设,加强水产养殖业的科技推广力度。

Based on the Nerlove model, the product output and price data of freshwater aquaculture, marine aquaculture of 2000-2013 yearswas used to analyze the supply response of freshwater and marine aquaculture in China. The results showed that the effect of the early output on the supply of freshwater aquaculture was relatively high, and the price had no significant effect on the yield of freshwater aquaculture. However, the price had a significant effect on the yield of marine aquaculture. Therefore, in order to ensure the long-term effective supply of aquatic products to meet the growing demand for aquatic products, the subsidy policy of fishermen and the construction of information services need to be improved, the promotion of science and technology of aquaculture should be strengthened.
