【摘要】：在黑龙江大豆种植面积锐减和自然灾害加重的背景下,掌握大豆种植格局和相应的纯费率对制定大豆种植政策和保险政策,保障大豆粮食安全有重要意义。本研究依据1993~2012年黑龙江13个地市和农垦总局(ARB)20年的播种面积和产量数据,运用统计学和单产分布模拟推导法分析了黑龙江播种面积和分布格局变化,并厘定了相应的大豆保险纯费率。结果表明:黑龙江大豆播种面积在2009年达到最大,随后逐年锐减,2012年为260万hm2,仅为2009的53.5%。2012年,齐齐哈尔、黑河和农垦总局为黑龙江大豆三大种植区,占全省的56.85%,费率分别为6.52%、3.96%和2.29%,全省13个地市和农垦总局的费率范围是2.29%~8.79%,平均值为5.06%。齐齐哈尔种植规模大,费率相对较高,在灾害防御投入、财政补贴等方面宜优先考虑。
[Abstract]:Under the background of the sharp decrease of soybean planting area and the aggravation of natural disasters in Heilongjiang, mastering the soybean planting pattern and the corresponding pure premium rate is of great significance for making soybean planting policy and insurance policy, and ensuring the safety of soybean grain. Based on 20 years' sowing area and yield data of 13 cities and ARB in Heilongjiang during the period of 1993~2012, the sowing area and distribution pattern of Heilongjiang were analyzed by statistics and yield distribution simulation deduction method, and the corresponding pure premium rate of soybean insurance was determined. The results showed that the soybean sown area in Heilongjiang reached the maximum in 2009, followed by a sharp decrease year by year, 2 million 600 thousand Hm2 in 2012, and only 53.5% of 2009. In 2012, Qigihar, Heihe and Nongken Bureau were the three largest soybean planting areas in Heilongjiang Province, accounting for 56.85% of the total Province, the rates were 6.52%, 3.96% and 2.29%, respectively, and the rates of 13 cities and reclamation offices in the whole province were 2.29%~8.79%, with an average of 5.06%. Qigihar has large scale and relatively high rate, which should be given priority in disaster defense input and financial subsidy.

【正文快照】： 中国自2001年加入世贸组织(WTO),实行农产品贸易自由化后,进口大豆逐年增长。2005年,中国成为世界上最大的大豆进口国,进口达2 659万t。2013年大豆进口总量6 338万t,创历史新高。黑龙江省在大豆进口和收益低效的冲击下,种植面积锐减,格局也发生了较大变化。在此背景下,近年来,
