The first stage, continuous rising period: from April 2006 to April 2007, the domestic pork price rose steadily, from 9.9 yuan/kg in April 2006 to 13.6 yuan/kg in April 2007, with an increase of 3.7 yuan/kg, with an increase of 37.3%. From May 2007 to March 2008, it was a period of rapid growth, and the price of pork rose rapidly, from 14.3 yuan/kg in May 2007 to 22.8 yuan/kg in March 2008, with an increase of 8.5 yuan/kg or 60.8%. The direct trigger of this round of pork price increase was the outbreak and widespread spread of porcine blue ear disease in 2007, which led to a large number of pig deaths and sow abortions, which greatly hit pig production. In addition, the snowstorm around 5438+ 10 in June 2008 caused a large number of pig deaths. The contradiction between supply and demand of pork in the market has intensified and the price has risen rapidly. At the same time, the rise of feed price, production cost and financial cost is also an important reason for the high price of live pigs. In the second stage, the period of high decline: from April 2008 to May 2009, the domestic pork price dropped sharply, from 22.8 yuan/kg in April 2008 to 14. 1 yuan/kg in May 2009, with a drop of 38.2%, reaching the level of May 2007. At present, the price of pork has fallen sharply, and the number of live pigs has increased, mainly because the supply exceeds the demand. In addition, affected by the economic crisis, the consumer price index continued to decline, and the overall price level was low, which in turn affected the trend of pork prices. The third stage, the upward period of shock: from June 2009 to June 5438+February 2009, domestic pork prices began to fluctuate upward, but the increase was relatively limited. During this period, with the increase of inflation expectations, the prices of agricultural products also rose as a whole. The price of live pigs that consumers are most concerned about began to stabilize after continuous decline, and some areas rebounded. This is only a seasonal increase, and the increase is limited. The fourth stage, the continuous decline period: the domestic pork price has been falling continuously since June 20 10. The reasons for the recent continuous decline in the price of live pigs are not only the short-term factors such as the decline in market demand after the Spring Festival and the epidemic situation in some places, but also the long-term factors such as the periodic adjustment of live pig production has not yet ended and the stock of live pigs is still high. I'm glad to answer the landlord's question. Please forgive me if there is any mistake.
